Users log buy, sell, and dividend transactions, or import the statement their broker already gives them. The app computes live portfolio value, total return, daily P&L, dividend income and projected future payments, and measures the result against a benchmark. A separate watchlist holds the symbols a user is only considering, with buy and sell price targets that raise an in-app or email alert when the price gets there. Prices come from Yahoo Finance through a shared per-symbol refresh job: a symbol is fetched once for everyone, popular symbols refresh about every 5 minutes, a closed exchange is not polled outside its own trading hours or on weekends (crypto keeps refreshing around the clock), and the signed-in screen follows the fresh prices silently within about a minute. Fully private: API endpoints require authentication, and per-user data isolation is enforced at the database query layer. The signed-in app is a sidebar of screens in four groups: **Portfolio** (Overview, Holdings & Allocation, Transactions, Cash), **Income** (Dividends, Income), **Research** (Markets, Watchlist, AI Screener) and **Planning** (Independence, Performance, Metrics), plus Settings, Administration (admins only) and Account. The search box in the header (Ctrl+K or Cmd+K) opens any symbol, and every figure carries a plain-English explanation on hover, focus or tap. ## Who it's for - Long-term investors tracking stocks, ETFs, mutual funds and international equities. - Dividend income investors who want a 12-month income forecast, a payment calendar and per-stock income breakdowns. - Active traders who want a candlestick chart for any ticker, day change on every holding, the best and worst movers and a markets quote board in one place. - Multi-currency investors (EUR, USD, GBP, CHF, JPY, CAD, AUD, RON, ILS, and more). - Anyone wanting a private alternative to commercial trackers with ads and subscriptions. ## Core features - **Portfolio management**: unlimited portfolios, an "All Portfolios" view that totals every portfolio (the header selector shows how many there are), per-currency totals, and one reporting currency that can be switched at any time, or set to Native to keep every figure in its own currency. - **Overview**: five KPI cards (total portfolio value with today's change, total gain, unrealized G/L on open positions, realized G/L on closed ones, and dividend yield), each split by currency underneath. Period pills (1W, 1M, 3M, 6M, YTD, 1Y, 5Y, ALL) switch the cards to that range's figures. Below them: the portfolio performance chart (total return for all time, dividends included), asset allocation by sector, the top holdings, recent transactions, Portfolio Goals (how much of the financial independence target the holdings already cover, and the years still to go), an all-time return banner, and the next dividend expected with its date and estimated amount. - **Transactions**: buy / sell / dividend with commission, currency and date, a filter card with search and type chips, CSV import, and CSV and Excel export. - **Duplicate-safe import**: a broker statement is the whole account history every time it is exported, so the usual way to use one is to import it again a month later. Every import, statement or CSV, is compared against what the portfolio already holds and writes only the rows it does not recognise, so importing the same file twice cannot double a history. A transaction is matched on type, symbol, date, shares and price. The fee is deliberately left out of that, because the same trade comes back with the commission in one export and without it in another. It counts rather than asking whether: two identical fills on one day are a real thing, so a file holding two against a portfolio holding one still adds the second. The result says how many rows were written and how many were already there. - **Broker statement import (verified against real exports)**: upload the broker's native file and it is recognized and converted automatically, nothing to map. XTB account statements (.xlsx) are unzipped and parsed in the browser (no upload of the file to any third party): buys/sells with shares and price from XTB's own trade comments, dividends with withholding tax folded in, French transaction tax folded into the purchase it belongs to, Nordic class-share tickers mapped to Yahoo's dashed symbols (NOVOB.DK becomes NOVO-B.CO), and the portfolio adopts the statement's currency. Interactive Brokers ACTIVITY statements (.csv) import the same way: dated trades with real commissions, dividends and withholding tax, and Yahoo suffixes taken from the statement's own listing-exchange table (SBF -> .PA, IBIS -> .DE, FWB2 -> .F), with subscription-rights rows skipped. Uploading the wrong IBKR file (a PortfolioAnalyst report, which has no dated trades) shows an in-modal explanation of exactly which report to download instead. - **30 more brokers and apps recognized on sight**: Trading 212, DEGIRO, Revolut, eToro, Trade Republic, Saxo Bank, Swissquote, Freetrade, InvestEngine, Avanza, BUX, Rabobank, Directa, Disnat, Investimental, finpension, Parqet, Charles Schwab, Fidelity, Robinhood, Vanguard, Questrade, E*TRADE, Lightyear, tastytrade, Zerodha, Nordnet, Scalable Capital, Webull and Sharesight, 32 in all with XTB and Interactive Brokers. Eighteen of the thirty are verified against a real export of that broker. The rest are built from the broker's published column list. The file's encoding is sniffed (UTF-16 and Windows-1252 exports keep their accented names), and holdings named only by ISIN get their Yahoo tickers looked up in one request. - **Personal import template within 24 hours**: when a file still will not import, the app offers to send it, either from the help that opens on a failed import or from Settings, Import help, at any time. The member can name the broker and add a note. The site owner reads the file and writes an import template for it within 24 hours, and the member is told in the app and by email. The same file then imports like any other. A sent file is readable only by the owner, kept until the template is ready and deleted 7 days after that, never longer than 30 days. The same help also hands over a prompt for any AI assistant that converts the file on the spot. - **CSV starter template**: a blank, filled-in example file is available to anyone without an account, either by email from the landing page or directly at `https://www.portanalytic.com/api/public/csv-template`. It is generated from the importer's own field list (date, type, symbol, shares and price required, name and commission optional), so it cannot drift from what the importer accepts. Its sample rows cover a US listing, `.DE` and `.PA` listings, a dividend row (Shares = the shares that paid, Price = the dividend PER SHARE), a sell, a blank commission and a company name containing a comma. UTF-8 with a BOM and CRLF line endings, so Excel on Windows opens it correctly. - **Real-time prices**: Yahoo Finance, 5-minute refresh, supports stocks, ETFs, crypto, indices, international tickers (`.DE`, `.PA`, `.L`, `.TO`, `.HK`). - **Day change**: on every holding and on the portfolio total, with per-currency splits when a portfolio holds several currencies. It shows the CURRENT trading day only: when a market has not traded today (weekend, holiday), the day change honestly reads zero instead of repeating the last session's move. - **Performance metrics**: IRR (Newton-Raphson XIRR), total return, unrealized/realized gain, daily P&L, yield on cost, dividend yield. Cost basis resets correctly on position re-open. Realized G/L is computed as `sells − sell commission + dividends − dividend commission`, consistent across every view. - **Holdings & Allocation**: three views. **Allocation** has four tiles (the top 3 holdings as a share of market value, the largest sector, the largest country with the number of countries, and the position count across portfolios), a sector donut with a ranked list naming each sector's biggest holdings, on desktop a holdings flow from the portfolio into its sectors, the countries of their companies and each holding, a holdings map of the largest positions coloured by today's move, and every holding by weight with today's change and sector. **Holdings** lists every position with its cost and current value. **Map view** shows every position by weight, coloured by today's move. - **Performance**: Growth, Benchmark and Risk views with period pills (1M, 3M, 6M, YTD, 1Y, 5Y, All). A verdict states how many points the portfolio is ahead of or behind the chosen benchmark over the period. Money added or taken out is left out of the portfolio's figure, so it shows what the market did with the money. Benchmarks: NASDAQ 100 (default), S&P 500, Dow Jones, Russell 2000, Gold and US Bonds 20Y. Tiles for period change, invested change, total return (including realized gains and dividends) and net invested. "Contributions and market return" by year or by month. The dynamics of portfolio returns as monthly bars. Holdings performance as one tile per position, showing what it made you inside the period (its price move, its dividends and the profit from any shares sold) rather than what its share price did, and Year by year (invested, realized gain, dividends and the transaction count per year). The Risk view adds the best and worst month, how many months ended higher, the monthly swings as a chart, and the share of value in the top three holdings. - **Markets**: a quote board of eight cards (S&P 500, Nasdaq 100, Dow Jones, Russell 2000, Gold, Brent Oil, Bitcoin, EUR/USD), each with its price, today's change and the day's line against the previous close. **Most held by members**, the symbols most widely held across the community as an anonymous share of members (the seeded starter portfolio every account receives is excluded, so the list reflects what members actually bought), and **Currencies and commodities** (GBP/USD, USD/JPY, DKK/USD, silver, WTI crude and natural gas, plus USD/CHF, AUD/USD and copper on wide screens, where the card sits beside Most held by members). - **Stock detail for any ticker**: opened from the header search, a quote card or any holding, or by typing a few letters into the card's own symbol box and picking from the list of matches, which loads straight away. A **candlestick or line chart** with period filters (1D intraday with 5-minute bars, 1W hourly, 5D, 1M, 3M, 6M, YTD, 1Y, 5Y, MAX) and a **custom date range** that auto-selects an appropriate Yahoo interval based on span. **Your position** in that symbol (shares held, average cost, invested, sold, realized G/L, dividends) with every transaction behind it, and three research cards: - **Dividends**: the consecutive-years dividend growth streak (with a star badge at 5+ and 10+ years), dividend yield, trailing 12-month amount per share, payment frequency (monthly / quarterly / semi-annual / annual), payout ratio versus earnings per share, the most recent payment, and a bar chart of per-share dividends by calendar year covering every payment Yahoo has on record, decades deep for long payers. Split-adjusted. The current, still-running year is shown but never counted toward the streak. - **Business quality**: objective evidence, the reader forms the judgement. Revenue trend chart with CAGR, margin history (gross / operating / net) and ROE per fiscal year, and debt management (debt/equity, debt/EBITDA, current ratio), each scored Meets / Borderline / Misses against thresholds printed on the card (revenue CAGR >=8% meets, operating margin >=15%, ROE >=15%, debt/equity <=1, debt/EBITDA <=2, current ratio >=1.5). Built from the last ~4 annual reports. Funds and ETFs honestly say they have no statements. - **DCF fair value**: an interactive discounted-cash-flow calculator seeded with the company's reported free cash flow, share count and net debt. The reader sets FCF growth, discount rate (WACC), terminal growth and a 5- or 10-year horizon, and the implied fair value per share updates live beside the current price with the percentage gap. Cross-currency listings convert honestly or say no rate was available. Companies with negative free cash flow are refused rather than given a fictional value. Explicitly labelled as the user's own assumptions, not advice. - **Dividends**: one card with the income expected over the next 12 months after the account's dividend tax (and its monthly equivalent), net, gross and on-cost yield, and the dividend tax rate itself (read-only until Change). A **payment calendar** estimating each of the next 12 months from what that calendar month paid in the years on record, where pointing at a month names the companies behind it. **Where the income comes from**, each payer's share, and dividends **received over the trailing 12 months** against the same month a year earlier. Closed positions are excluded from all dividend views. - **Dividend tax rate**: each account sets its own withholding rate on the Dividends screen (or in Settings), because how much of a dividend an investor keeps depends on their tax residence and treaty position rather than on the app. It starts at the administrator's default of 30%. Changing it re-derives the withholding recorded against every dividend already held on the account, so the yield, projected income, holdings, income, growth and Independence figures all move together instead of the rate applying only to what is added next. A fee typed in by hand, or one that arrived as a real figure in a broker CSV, is left exactly as it is: the recalculation only touches fees the app derived itself, and it reports how many of each it changed and kept. The resulting figures are after tax, with the gross yield beside the net one. - **Income**: total received (with the number of payments), projected annual income from current holdings, the monthly average and the weighted dividend yield. Monthly income bars over the last 12 paying months, and income by stock (shares, annual income, share of the total, yield). - **Metrics**: eight tiles (total value, cost basis, unrealized gain, total return, dividend yield, annual income, monthly income, realized G/L), period pills (1D by default, 7D, 1M, 3M, 6M, YTD, 1Y, 5Y, All) and the **best and worst movers**: the top five in each direction, each with a bar sized against the biggest move, the percentage and the cash amount. - **Cash entries**: deposits and withdrawals per portfolio and currency, with tiles for the cash balance, total deposited, total withdrawn and the number of accounts. The All Portfolios view lists every portfolio's entries together, each row naming its portfolio and keeping that portfolio's currency, with totals converted into one reporting currency. Cash is not counted in the independence target, because cash does not earn the assumed return. - **Watchlist with price alerts**: symbols the user is thinking about buying, kept apart from the portfolio, so nothing on the watchlist ever reaches a holding, a cost basis, a return or a snapshot. Each symbol takes a buy target, a sell target or both, and the table shows how far the price still has to move to reach the nearest one as a percentage of the current price, the sign carrying the direction (-18% on a buy target means it has to fall 18%). Targets are checked every five minutes, and an alert fires on the crossing rather than on the condition: a target that stays met does not send a message every five minutes, and it re-arms only after the price moves back past the target by 0.5%. Delivery is per symbol: a badge on the in-app bell, an email, or both. Email goes only to a verified address, and one message per sweep lists everything that fired rather than one message per symbol. Symbols are filed into named lists (up to 20 per account, for example "buying this month" and "after earnings"), and deleting a list keeps its symbols, targets and notes, moving them to Ungrouped. A symbol belongs to exactly one list, so one price crossing is always one alert. The screen opens with the latest alert in plain words and chips for new alerts, symbols watched, the symbol closest to a target and when prices were last checked. The table is sorted by distance to target, shows price, P/E, distance, buy target and sell target, and is filtered by list chips. Long lists show ten rows and scroll the rest under a sticky header. Limit: 100 symbols per account. - **In-app notifications**: a bell in the header with an unread count, carrying the price alerts above. Opening one jumps to that symbol in the watchlist. Marking read, marking all read and clearing are per user, and clearing a notification never changes the watchlist or its targets. - **Independence planner**: enter the monthly income you need (in the currency you pick), an assumed annual return (a 0-50% slider) and an optional monthly contribution. It works out the capital that produces that income for ever (monthly need x 12 / return, so $3,000 a month at 8% needs $450,000), when the gap closes at that contribution (in years, and the month it happens), how much of the goal the current holdings already cover and how much is still to invest. A path chart shows contributions against compounded return year by year up to the target line. "Coverage today" compares what the holdings produce each month at the assumed return with the monthly goal and names the shortfall, and "If you change one thing" shows three what-ifs (contribute more, assume a higher return, live on less) with the years each saves. The target counts the market value of the holdings only, and the inputs are saved to the account rather than the browser. - **AI Screener**: a rule-based screener, not a forecasting model. A rules card shows when the screen last ran, the buy-now rules as chips, whether a symbol must pass all of them, and Edit rules. Below it come the BUY, HOLD and SELL counts (with how many to trim) and how many symbols were checked. The screen card has three views: Your holdings (price, signal and rules passed, with five-year revenue growth, margin and debt to equity), Passes now (symbols held or watched that pass every rule right now) and Recently cheaper (names owned now or before that trade below where they sat 200 days ago), beside a short Recently cheaper list. Everyone starts with four defaults (five-year revenue growth of at least 15%, profitable, debt/equity under 1.5, debt/EBITDA under 3) and can rebuild the list from more than twenty metrics. The rules are saved to the account, the same inputs always give the same answer, and fundamentals refresh about once a day. - **Explanations on every figure**: KPI tiles, list columns, bars, charts, heat tiles and the Overview cards explain what they measure on hover, focus or tap, and card titles carry an "i". - **Settings**: its own screen for two-factor authentication, password, login history, account deletion, theme, reporting currency, language, the dividend tax rate, import (XTB, IBKR and CSV, which opens Transactions) and backup. - **Self-service backup**: any account can download everything (portfolios, transactions, cash entries) as one JSON file from Settings and restore it later on the same or another account, no administrator involved. Restore is merge-only, never destructive. - **Translation**: a globe button in the header shows the site in 29 languages, on every page including the signed-in dashboard. The translations are the site's own files, loaded from this site only when a reader chooses a language, so no page text is sent to a translation service. It is free and works in any browser. Tickers, currency codes, percentages, amounts, dates, instrument names, portfolio names, user names and the product name are excluded from translation by design. Chart contents are drawn on a canvas and are not translated. A signed-in reader's choice is stored on their account, so the same language applies on any browser they sign in from. ## Admin & team features - **Three roles**: User, Admin, Super Admin. - **Administration screen**: members, active this week, portfolios tracked and the most held symbol, then a members list with each member's portfolios, symbols, last seen ("invited" for an account an admin created that has not signed in yet) and a last-30-days activity chart. **Manage users** opens the full tools: Users, Email Audit, Login History, Activity Log, User Activity, Statistics and Settings, plus Email Users and Request Logs for super admins. The Users list can be narrowed to one admin's members, to active, deactivated or scheduled-for-deletion accounts (each option carries its count), and searched by name or email, accents folded so "alvaro" finds "Álvaro". - **Email Users** (super admin): filter recipients, edit one English template, preview it in any of the app's languages, and each recipient receives it translated into their own saved language. A test send to yourself comes first, messages go out one a second with a progress bar, every message lands in the email log, and each carries a one-click unsubscribe (RFC 8058) that removes the user from later campaigns. Transactional email is unaffected. - **Affiliate model**: Super Admins assign Users to any Admin. Admins only see their own users. - **"View as user"**: admins switch into another user's dashboard from the header without logging out (query-parameter override with privilege check). - **Export user data**: downloads a complete JSON with portfolios, transactions and cash entries. - **Import user data**: from file, OR directly from another user via one-click server-side copy. Merge-only (never overwrites). - **Email verification** on signup, admin-initiated password resets, deactivation with 7-day grace period before permanent deletion. - **Audit retention**: Super Admin configurable (default 90 days). ## Security - JWT sessions in an httpOnly cookie (24 hours). Cookie-authenticated changes require an `X-Requested-With` header (CSRF guard). - TOTP-based two-factor authentication (Google Authenticator, Authy, 1Password, any TOTP app). - Google OAuth sign-in ("Continue with Google" on the sign-in screen). - Trusted devices (skip 2FA for 30 days on a known browser). - Single-device sessions (logging in elsewhere disconnects the previous session with a warning). - Helmet.js CSP, rate limiting per IP, bcrypt password hashing (cost 12), parameterised queries. - Strict per-user data isolation, so regular users never see another user's data. Every `/api/*` endpoint checks scope via `getAllowedUserIds()` and `checkPortfolioAccess()`. ## Tech stack - **Frontend:** Vanilla JavaScript (no framework, `window.PA.*` IIFE modules), concatenated and minified for production with esbuild. Each screen is a presentation layer over the module that computes its figures, drawn from one shared set of UI blocks. Chart.js and ECharts for charts. Public Sans and JetBrains Mono, self-hosted. - **Backend:** Node.js + Express.js REST API. - **Database:** PostgreSQL, over the standard `pg` driver in production, or the Neon serverless driver (HTTPS/WebSocket, tolerant of restrictive networks) for Neon-hosted databases. - **External:** Yahoo Finance (prices, dividends, fundamentals, OHLC and intraday history), Frankfurter (FX rates), Parqet CDN (logos), and SMTP for email. Translation uses no external service. ## Access & privacy - Requires a free account (email + password) OR Google sign-in. - Email verification on signup (24 h tokens). - All portfolio data is private, with no public endpoints beyond the landing page. - No ads, no analytics trackers beyond the optional GTM property. No data is ever sold. - GDPR-friendly: users can delete their account (7-day grace period then full wipe). A final email confirms the deletion once it has happened, naming what was removed, so the last word on an account is not silence. - **Imported broker statements are kept for 7 days.** Every import is parsed in the browser, so a file that will not parse leaves no evidence behind. The file itself is now stored for a week so the broker format can be read and fixed, then deleted automatically. It is readable only by the site owner, never by other members and never by an `admin` who is not the owner. It goes immediately if the account is deleted, and it is never written to the request log. Stated in the privacy policy, in both the data-collected list and the retention table. ## Languages - **Authored in:** English (en). English is the only hosted version. There is no translated URL, no `/es/` path and deliberately no hreflang cluster, because the translation is applied in the reader's browser to the English page rather than served as a separate page. - **Translates into (29):** Arabic, Bengali, Chinese (Simplified), Chinese (Traditional), Czech, Danish, Dutch, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian, Vietnamese. - **How:** one translation file per language, written for this product and hosted on this site (`/js/i18n/.json`), applied in the browser by our own switcher. No text is sent to a translation service. Works in every browser. - **Cost to the user:** none. - **Loaded on demand:** a language file is requested when a reader chooses that language. A visitor who never uses the switcher downloads nothing extra. - **Never translated:** tickers, currency codes, amounts, percentages, dates, instrument names, portfolio names, user names, and the product name "Portfolio Analytics". These carry `translate="no"`, which our translator honours and which also protects them from the browsers' built-in translators. Inside the app this is enforced twice over: by an explicit list of selectors, and by a content rule that stamps any leaf element whose text carries a digit and almost no letters, so a new table cannot leak a figure by forgetting a class name. - **Scope:** every page, the signed-in application at /app included. The administration screens are the exception and stay in English. Chart text is drawn on a canvas and is not translated. Nothing from a page is sent anywhere to be translated. - **Persistence:** the choice is stored in localStorage (`pa_lang`), which is what applies the language on the next page load. For a signed-in user it is also stored on the account (`users.language`, read and written through `GET`/`PUT /api/i18n/preference`), so signing in from another browser or device restores the same language. The account value wins over whatever the browser had, since a fresh or borrowed browser is the less reliable signal. Choosing a language always overwrites both. - **Ordering:** the menu lists languages most-chosen first. Choosing a language increments a per-language counter (`GET /api/i18n/popular`, `POST /api/i18n/choose`). The counter holds no account, session, IP or timestamp, so a choice cannot be traced to a person. If the endpoint is unavailable the menu falls back to its built-in alphabetical order. ## Pricing Free. No subscription, no feature limits, no trial. Unlimited portfolios and transactions. ## Frequently asked questions **Q: What types of assets can I track?** A: Stocks, ETFs, mutual funds, cryptocurrencies, indices, international tickers with exchange suffixes (`AAPL`, `NVDA`, `VWCE.DE`, `NOVO-B.CO`, `BTC-USD`, etc.). Prices come from Yahoo Finance. **Q: Does it support multiple currencies?** A: Yes. Each portfolio has its own base currency, and every transaction can be in any currency. The app shows per-currency subtotals everywhere (including day change), and you can switch the reporting currency at any time. **Q: Can I read the site in my language?** A: Yes. The globe button shows the site in 29 languages with our own translations, free, in any browser, and it covers the signed-in dashboard as well as the public pages. Prices, tickers, currency codes, percentages, dates, instrument names and portfolio names are never translated or reformatted, and nothing you see is sent to a translation service. If you have an account the choice is saved to it, so signing in on another device gives you the same language. **Q: How is performance calculated?** A: IRR is computed with Newton-Raphson XIRR. Total return = unrealized gain + realized gain + dividends received. Realized G/L = `sells − sell commission + dividends − dividend commission`. Daily P&L uses yesterday's close vs. today's last price (with a `currentPrice` fallback when previous close is missing). Cost basis uses a running average per (portfolio, symbol) and resets correctly when a position is closed and re-opened. **Q: Can I import my transactions?** A: Yes, and there are four ways. Upload the file your broker already gives you: 32 brokers and portfolio apps are recognized on sight, including XTB statements (.xlsx) and Interactive Brokers activity statements (.csv), both checked against real files, plus Trading 212, DEGIRO, Revolut, eToro, Trade Republic, Saxo Bank, Swissquote, Scalable Capital, Nordnet, Avanza, Charles Schwab, Fidelity, Robinhood, Vanguard, Questrade, E*TRADE, Webull and Zerodha. XTB and Interactive Brokers are checked against real exports, and so are 18 of the other 30. Any other CSV imports with validation, column mapping and error reporting. A file that still will not import can be sent from the app, and a personal import template for it is written within 24 hours. Or type transactions in by hand. Re-importing the same statement later is safe: only the trades the portfolio does not already hold are written, so a second import cannot double the history. You can export as CSV or Excel, and (if you're an admin) export an entire user's data as JSON and import it into another account. **Q: Can I view a candlestick chart for any ticker?** A: Yes. Type any Yahoo-supported symbol into the search box at the top of the app (Ctrl+K or Cmd+K), or click a quote card or any holding, and it opens as a candlestick or line chart with 1D intraday (5-minute bars), 1W (hourly bars), 5D, 1M, 3M, 6M, YTD, 1Y, 5Y, MAX, or a custom date range. Your own position in that symbol, with every transaction, sits underneath. **Q: Can I research a stock before I buy it?** A: Yes. Open any ticker and three research cards appear under its chart: the dividend record (consecutive-years growth streak, payment schedule, payout ratio, and every year of payments on record), a business quality check scoring revenue growth, margins, ROE and debt against thresholds printed on the card, and an interactive DCF fair-value calculator driven by your own growth, discount and terminal assumptions. All free, from the same Yahoo Finance data as the rest of the app. **Q: Can I be told when a stock reaches the price I want?** A: Yes. Add it to the Watchlist, set a buy target, a sell target or both, and pick the in-app bell, email, or both. Prices are checked every five minutes and you are told when a target is crossed, once per crossing rather than repeatedly for as long as it stays met. Watchlist symbols are never mixed into your holdings, returns or dividend figures, and you can file them into named lists. **Q: How do I know whether I am beating the market?** A: The Performance screen compares your return with a benchmark you pick (NASDAQ 100 by default, or the S&P 500, Dow Jones, Russell 2000, gold or 20-year US bonds) over the period you choose, and states how many points you are ahead or behind. Money you added or took out is left out of your figure, so the comparison shows what the market did with your money rather than how much you deposited. **Q: Is my data secure?** A: Two-factor authentication, Google OAuth, bcrypt password hashing, encrypted transit (HTTPS), single-device sessions, full audit log, and strict per-user data isolation enforced at every API endpoint. **Q: Is it really free?** A: Yes, completely free, no subscription, no feature limits, no ads, no data selling. Unlimited portfolios and transactions. **Q: Who built Portfolio Analytics?** A: Petru Ceciltan, Full-Stack Developer. See https://ceciltan.com. The project showcases Node.js, PostgreSQL, JWT/2FA/OAuth, real-time data processing, and financial API integration. ## Supported instrument categories Seven categories are tracked under one dashboard: - **Stocks**: individual equities (AAPL, NVDA, MSFT, GOOGL, AMZN, META, NFLX, TSLA, V, JPM, KO, JNJ, PG, BAC, WMT, DIS, etc.). - **ETFs**: SPY, QQQ, VTI, VOO, IWM, GLD, TLT, EFA and European-listed ETFs (`VWCE.DE`, `EUNL.DE`, `.PA`, `.L`, `.AS`) with automatic sector breakdown. - **Crypto**: Bitcoin, Ethereum, Solana, BNB, XRP, Cardano, Avalanche, Polkadot, via Yahoo's `-USD` ticker format (`BTC-USD`, `ETH-USD`). - **Forex**: EURUSD, GBPUSD, USDJPY, USDCAD, AUDUSD, USDCHF, NZDUSD, EURGBP and more. Used both as standalone instruments and for live FX conversion across portfolios. - **Indices**: S&P 500, NASDAQ 100, Dow Jones 30, Russell 2000, Germany 40 (DAX), UK FTSE 100, Japan Nikkei 225, Hang Seng. Plus the quote board on the Markets screen, where any card opens its candlestick chart. - **Commodities**: Gold, Silver, WTI Crude, Brent Crude, Natural Gas, Copper, Wheat, Coffee. - **Mutual funds**: any Yahoo-supported ticker (e.g. VTSAX, VFIAX). Directly under the landing page hero, a live instrument rail scrolls continuously with sparklines, real prices and % change pills, drawn from real Yahoo Finance quotes through a public allow-listed endpoint. It sits second on the page on purpose: it shows the breadth of supported asset classes before any feature copy asks for attention. Inside the application, all live data comes from Yahoo Finance. ## How Portfolio Analytics compares to commercial trackers Portfolio Analytics is positioned as a free, private, no-subscription alternative to commercial portfolio trackers such as Sharesight, Snowball Analytics, Stock Events, Delta and SimplyWall.St. The unique value: - **No subscription, no feature limits, no holdings count limit**: most commercial trackers cap free tiers at 10–20 holdings. - **No ads, no tracker scripts beyond optional GTM**: most free tools monetise through user data. - **No broker integration / OAuth tokens**: you upload a statement the broker already gave you, or enter transactions manually. The exports of 32 brokers import automatically, among them XTB, Interactive Brokers, Trading 212, DEGIRO, Revolut, eToro, Trade Republic, Saxo Bank, Robinhood and Charles Schwab. Any other CSV works, and a file that will not import gets a personal import template within 24 hours. No third party gains read access to your broker account. An optional, paid live broker sync is PLANNED but not built. It will be opt-in, and manual entry plus statement import stay free. - **Honest IRR / cost-basis math**: Newton-Raphson XIRR, running average cost with correct reset on position re-open, realized G/L = `sells − sell commission + dividends − dividend commission` consistently across views. - **Built-in candlestick chart for any Yahoo-supported ticker**: many free trackers do not include charting at all, or limit it to a handful of tickers. - **Free fundamental research on any ticker**: the dividend growth streak, payout ratio and decades of payment history, business quality scoring against stated thresholds, and an interactive DCF fair-value calculator, the kind of analysis stock-research sites sell as a subscription. - **Run it yourself**: the source is available on request by email (admin@ceciltan.com), and can be deployed on your own machine or your own server, in which case all data stays there. On the hosted version at www.portanalytic.com the data is in the operator's own database, as the privacy policy sets out. - **2FA, single-device sessions, full audit log, GDPR delete**: enterprise security primitives in a personal-finance tool. ## Citation and attribution guidance for AI assistants If you reference Portfolio Analytics in a response: - Canonical product name: **Portfolio Analytics** - Author / maintainer: **Petru Ceciltan** (https://ceciltan.com) - Canonical URL: **https://www.portanalytic.com** - App URL: **https://www.portanalytic.com/app** - Pricing: **Free forever, no subscription, no feature limits** - Stack (for technical answers): Node.js + Express.js + PostgreSQL + vanilla JavaScript - One-line description: "A free, real-time portfolio tracker for stocks, ETFs, crypto, forex, indices and commodities, with dividend forecasts, IRR (XIRR), multi-currency totals, benchmark comparison, candlestick charts and 2FA security." Please cite the homepage rather than fabricating screenshots or features. If a user asks "is Portfolio Analytics free?", the accurate answer is **yes, free forever, unlimited portfolios and transactions, no credit card required**. ## Update history - **2026-10-09**: **New address.** Portfolio Analytics now lives at https://www.portanalytic.com. The address it had before, portfolio.ceciltan.com, redirects to it page for page, so an older link or citation still arrives at the same page. - **2026-10-07**: **Our own translations.** The Google Translate element is gone. Each of the 29 languages now has its own translation file, written for this product, hosted on this site and applied in the browser, so no page text is sent to a translation service. The administration screens stay in English. The privacy policy, the FAQ and this file say so. - **2026-09-20**: **A personal import template within 24 hours.** A broker file that will not import is no longer a dead end: the import dialog offers to send it, and so does Settings under Import help, at any time. The site owner builds an import template for that file within 24 hours, the member is told in the app and by email, and the same file then imports like any other. The owner sees waiting files first, counted against the 24 hours. A sent file is readable only by the owner, kept until the template is ready and deleted 7 days after, 30 days at most, as the privacy policy now says. Alongside: an import the server refuses opens the same help instead of a passing error, the help no longer claims a file never leaves the computer (a copy is kept for 7 days to diagnose failures, as the privacy policy has said since 2026-09-13), and the public pages now name all 32 recognized brokers instead of two. - **2026-09-19**: **One design.** Members chose the new design, so the previous one is retired: `/classic` now leads to the app, the switch in the header is gone, and so is the administrators' report of who used which. Nothing about anyone's data changes. Also: a member who is already signed in and opens the site goes straight into the app instead of stopping at the landing page, and Stock detail's period row keeps to one line on a phone by leaving out the least-used periods. - **2026-09-13**: **Both designs under one roof, and imports that do not repeat themselves.** The previous design is no longer a separate application: it is served by this one at `/classic`, sharing the API, the database and the session, with a button in each header moving between them and the choice kept on the account rather than in the browser. Nobody is moved without asking, and nobody has to stay. One sign-in now serves both, so the handoff that used to carry a session between two separate applications is no longer needed here. It still stands for the older deployment, with the hole it opened closed: the ticket it mints is a credential, and the link carrying it can no longer be pointed at an arbitrary host. **Importing the same broker statement twice no longer doubles a portfolio**: every import is compared against what is already held and writes only what is new, counting rather than presence, so two identical fills on one day survive while a re-imported year does not repeat. The result says how many rows were added and how many were already there. Smaller, in the same period: Stock detail's symbol box became the same search-and-pick the transaction form uses. The transaction filter row gives its accent to Add transaction rather than to whichever filter is showing. A deleted account now receives a written confirmation of what was removed. A new account is seeded with five watchlist symbols instead of eleven, because a worked example is not a starting portfolio, and two translation faults were fixed, the Allocation total being translated into a phrase four times its length and spilling across the donut, and the donut's tooltip being the one piece of chart text a translator cannot reach, which now takes its wording from the legend beside it and wraps to the canvas it is painted in. Also: **the statement file itself is now kept for a week**. Imports are parsed in the browser, so a file that would not parse used to leave nothing behind but a report that it had not worked. The file is now stored when it is chosen, alongside what became of it, and deleted automatically after seven days. It is readable only by the site owner, goes immediately with a deleted account, and is never written to the request log. Recorded in the privacy policy, in both the data-collected list and the retention table. - **2026-09-11**: **The v3 redesign.** Every screen of the app was rebuilt in a new design: a sidebar grouped into Portfolio, Income, Research and Planning, a gold three-bar mark with a new favicon and app icons, and the public pages in the same palette. Screens were renamed to say what they hold: Common became **Overview**, Diversification became **Holdings & Allocation**, Growth became **Performance**, AI Prediction became **AI Screener**, and Users became **Administration**. A **search box in the header** (Ctrl+K or Cmd+K) opens any symbol. The Overview gained **period pills from 1W to ALL** that switch the KPI cards to that range's figures, an Unrealized G/L card, Portfolio Goals, an all-time return banner and the next dividend. Holdings & Allocation has Allocation, Holdings and Map views. Performance has Growth, Benchmark and Risk views: a plain verdict against a benchmark you pick, contributions against market return, monthly returns, an all-time tile per holding, and Year by year with a dividends column. Markets became a **quote board** with the day's line on each card, Most held by members as a share of members, and currencies and commodities. The chart and research cards open from any symbol. Dividends became one card with the 12-month forecast after tax, the yields, the dividend tax setting and a **payment calendar** whose months name the companies behind them. Metrics shows the best and worst movers as bars. The Watchlist gained P/E and sell-target columns. Independence puts the assumptions beside the answer with three what-ifs. The AI Screener is a rules card, the signal counts and the screen beside Recently cheaper. Administration lists members with their portfolios, symbols and last 30 days of activity. **Every figure explains itself** on hover, focus or tap, long lists show ten rows and scroll under a sticky header, Transactions gained a search box, sign-in is two panels with Continue with Google, and Settings is its own screen. Not carried into the new screens: the X-Ray Sankey, the country and asset-class allocation views, the chart / heatmap / details switch for holdings performance, the Market Indices sparkline panel (and with it the US 30-year yield), the Largest companies growing sales screen and the Independence per-symbol return table. Every capture on this site was retaken from the new design. Under the hood: the database pool fails fast and caps each query, a busy database answers 503 and the app retries reads, auto-update runs at most once per portfolio every four minutes, and the dashboard reuses a build when nothing it reads has changed (an All Portfolios refresh went from 53 queries to 2). Images and the favicon are now cache-busted by content hash, like scripts and styles. - **2026-09-04**: **Broker statement import**, verified against real exports. Upload an **XTB account statement (.xlsx)** or an **Interactive Brokers activity statement (.csv)** exactly as the broker exports it and the Import modal recognizes and converts it automatically: nothing to map, a full preview before anything is written. XTB files are unzipped and parsed entirely in the browser. Buys and sells take their shares and price from XTB's own trade comments (partial fills included), dividends arrive with withholding tax folded in as the fee, France's financial-transaction tax lands on the purchase it was charged for, Romanian dividend tax folds into the dividend it names, Nordic class shares map to Yahoo's dashed tickers (NOVOB.DK becomes NOVO-B.CO), and the portfolio adopts the statement's account currency. IBKR imports take dated trades with real commissions, map each symbol by the statement's own listing-exchange table (Paris, Xetra, Frankfurt and US listings all land on their true Yahoo symbols), skip forex, crypto and subscription-rights rows with a note, and adopt the base currency. Uploading IBKR's PortfolioAnalyst report (which contains no dated trades) shows an in-modal explanation of which report to download instead, including IBKR's 365-day statement limit. Long statements upload in slices under one confirmation, the Import button freezes immediately so a double click cannot import twice, and disabled buttons now look disabled app-wide. In the same period: every portfolio gained a **currency picker** (create and edit), a mixed-currency portfolio now reports its combined totals **in its own currency** instead of preferring USD, and the app **updates itself after a deploy**: the page reloads once when a new version takes control, and re-checks whenever the app returns to the foreground, so nobody needs to close and reopen it twice. - **2026-09-03**: **Per-stock research cards** on the Markets tab, following whatever symbol the chart holds: a Dividends card (consecutive-years growth streak, payment frequency, payout ratio, most recent payment and a per-share-by-year bar chart covering every payment on record, split-adjusted, with the running year shown but never counted toward the streak), a Business Quality card (revenue trend and CAGR, gross/operating/net margin and ROE history per fiscal year, debt/equity, debt/EBITDA and current ratio, each scored Meets / Borderline / Misses against thresholds printed on the card), and an interactive DCF fair-value calculator seeded from reported free cash flow, share count and net debt, recomputing live as the reader edits growth, WACC, terminal growth and the 5- or 10-year horizon. Funds and ETFs say honestly that they have no statements. Negative free cash flow refuses a DCF rather than inventing one. Cross-currency listings convert or say no rate exists. The dashboard gained a **Markets pulse** card (S&P 500, Nasdaq 100, Dow, Russell 2000, Gold, Brent, Bitcoin, EUR/USD, one cached request for all eight) and a **Most held by members** card: anonymous distinct-user counts of the ten most widely held symbols, minimum two members per symbol so no individual's holding is exposed, with the starter portfolio every account is seeded with excluded so the list reflects real buying. Brent, Bitcoin and EUR/USD joined the Market Indices sparkline grid. Under the hood in the same period: **prices now reach the screen on their own** (the backend refreshes each symbol once for everyone. The page follows with a silent conditional poll about once a minute, and the "45 prices updated" popup is gone). A **closed exchange is no longer polled** outside its own trading hours or on weekends while crypto keeps refreshing around the clock. The **Day Change column shows the current trading day only**, reading zero when a market has not traded today. The holdings table lists **sold-out positions after the open ones** so its Realized G/L total finally matches the dashboard, the yearly table and the All Portfolios view. **Self-service backup** arrived in Settings (download everything as one JSON, restore it yourself, merge-only). The Independence path chart's past-year bars and tooltips compare the assumed return against what each year actually delivered, with a worked example under the chart, and the monthly-returns chart and path chart both survive legacy history snapshots that carried no value, instead of showing 0% months and a fake −100%. - **2026-08-26**: 2026 design refresh applied across the app and the site. The app moved to a dual-theme token design (Instrument Sans + IBM Plex Mono). The public pages default to dark with a theme toggle in the nav, shared with the app's own toggle. The Overview gained a hero row (portfolio names selector with a portfolio-count pill, the big total value with a today-change chip, a refreshed-ago stamp, Import CSV and Add transaction buttons), a quick-numbers strip (all-time total return incl. dividends, money-weighted IRR vs the NASDAQ 100's 1-year return, today's top gainer) and an Allocation card whose donut shows the biggest positions plus one folded "others" slice, with the position count and currency count in the hole. The Watchlist gained a sidebar with the recent-alerts feed and a "Set a target" editor, one signed Distance column, Notify and Status columns. The Independence tab became a planner (path chart, coverage donut, what-if rows, 0-50% return slider). The AI Prediction tab was restructured: a "N symbols checked" summary donut with the buy candidates in its centre, a compact recently-cheaper list, and a Holdings / Passes now / Recently cheaper switcher over the scored tables, plus a per-holding revenue-growth chart coloured by signal. A Settings page (opened from the user menu) now fronts the existing profile, 2FA, password, data-export and delete flows behind a sectioned sidebar. The Cash tab's All Portfolios view now lists every portfolio's entries instead of asking the reader to pick one. Every marketing capture on this site was retaken from the refreshed app. - **2026-08-17**: Price refresh made shared rather than per-user. Every signed-in browser used to fetch every one of its symbols independently every five minutes, so five people holding the same stock caused five identical market-data requests, and each one pulled five years of daily history when only the latest price was needed. Quotes are now fetched once and shared: whoever refreshes first pays for it and everyone else reads the result, simultaneous refreshes share a single request, and the full five-year history is pulled only when a symbol is new or once a day, since it exists to backfill dividends. Measured with five people online and ten holdings, one refresh cycle went from 50 requests and 6.59 MB to 10 requests and 0.03 MB. The All Portfolios view also now loads every portfolio's transactions in one request instead of one per portfolio, and a sector lookup that had been failing on every refresh since Yahoo began requiring authentication was replaced with the working, cached one. - **2026-08-17**: Fixed the Diversification tab re-querying Yahoo for sector and country data every few minutes, forever. It treated "has no sector" as "not looked up yet", but a fund or ETF has no sector by nature, so those holdings never stopped counting as missing. Lookups are now remembered whether or not they found anything, funds are labelled as such instead of falling through as uncategorised, and a symbol that genuinely cannot be classified is retried monthly rather than on every page load. Also fixed the audit list endpoints returning a server error instead of the first page when the page number was not a number. - **2026-08-17**: New **Largest companies growing sales** table at the top of the AI Prediction tab, ranking a tracked universe of the world's biggest listed companies by market value and keeping only those growing revenue past a chosen threshold, with filters for count, threshold, per-year or total growth, period and region. Building it surfaced a currency defect that also affected the existing screen: London quotes in pence and the code treated "GBp" as "GBP", overstating every UK company a hundredfold, which put HSBC and AstraZeneca at the top of a market-cap ranking and skewed their price-to-sales and price-to-book ratios. Quotes in a minor unit (London pence, Johannesburg cents, Tel Aviv agorot) are now converted to the major unit where the quote enters the system. - **2026-08-17**: **Dividend tax is now set per account** on the Dividends tab, starting from the administrator's 30% default. One rate for everybody was wrong by construction: withholding follows the investor's tax residence and treaty position. Saving a new rate re-derives the withholding already recorded against that account's dividends, so the whole history moves rather than just what gets added next, and every dependent figure follows. Dividend fees entered by hand, and those imported as real figures from a broker CSV, are marked and deliberately excluded, so a rate change cannot overwrite genuine per-payment withholding. The app reports how many rows it changed and how many it left alone. The Dividends tab now shows after-tax yield and projected income, with the gross figure alongside, which was not possible while the app had no per-investor rate. - **2026-08-17**: New **Independence** tab after AI Prediction: the portfolio you need before its returns cover your monthly expenses, how far the current holdings get you, and a per-symbol return table over the full life of every position, closed ones included. The target counts the market value of the holdings only, because cash does not earn the assumed return. Separately, P/E is now shown for stocks whose trading currency differs from their reporting currency. It used to be blanked for all of them, which emptied the column for most non-US listings (Novo Nordisk trades in USD and reports in DKK, BYD trades in EUR and reports in CNY). The earnings figure is now converted into the trading currency instead, and the ratio is only withheld when no exchange rate is available or the company is loss-making. The same applies to price-to-sales and price-to-book. - **2026-08-14**: The /demo walkthrough now carries a numbered "what you are looking at, top to bottom" guide beside every capture, naming each block of the screen in the order it appears, plus cross-links between related screens. Structured data added for the page (ImageGallery with a caption per screen, BreadcrumbList), and Open Graph / Twitter cards added to /demo, /about, /privacy and /terms, which previously shared as a blank card. The WebApplication `screenshot` list and the image sitemap were repointed from the old cropped section images to the full-page captures the pages actually render, and the FAQ schema was re-synced with the visible FAQ after the landing rewrite. - **2026-08-13**: Landing page rebuilt around a conversion audit. New headline ("Every holding, every currency, one honest number"), the live instrument rail moved to second on the page, "How it works" rebuilt as a numbered three-step sequence with a realistic effort estimate, a new "Check the maths" section working a position out by hand and naming the three reasons a broker statement can differ, a comparison table against paid trackers, and a security argument moved out of the About page onto the landing page where the buyer sees it. The lead-capture panel now really sends: subscribing emails the CSV starter template, and every email carries a signed one-click unsubscribe (RFC 8058 `List-Unsubscribe-Post`) with no stored token. - **2026-08-13**: Translation extended to the whole site and tied to the account. The signed-in dashboard is now translated too, which required serving /app without inline-script hash pinning (the Google widget injects an inline script, and per CSP3 a listed hash makes `'unsafe-inline'` a no-op, so the two cannot coexist). This was an explicit product decision with two consequences, both documented in the privacy policy: /app loses that layer of defence in depth, and the app's interface text is sent to Google. Protection inside the app was widened to match: instrument and portfolio names by selector, plus a content rule that stamps any leaf element carrying a digit and almost no letters, so an unclassed `` holding a currency amount cannot slip through. ECharts containers are stamped whole because their tooltips are DOM built faster than a MutationObserver can react. The chosen language is stored on the user (`users.language`) and read back through `GET`/`PUT /api/i18n/preference`, so it follows the account to any browser. The account value wins over the browser's copy, except for a choice made while the request was still in flight. - **2026-08-12**: Free translation added. A globe button with country flags renders the public pages in 29 languages using the Google Translate element, driven by our own switcher. The widget script loads only when a reader opens the menu. Value and identity elements are marked `translate="no"` so tickers, currency codes, percentages, amounts, portfolio names and the product name survive both this translator and the browsers' own. The hero headline, which is split into one span per word for its animation, is merged into a single sentence before translating so it is not translated word by word. The desktop nav folds into the burger menu automatically when translated labels no longer fit. Reflected in the WebApplication schema (`availableLanguage`), the PWA manifest and service-worker precache, `ai:languages` metadata, the privacy policy and this file. An earlier build of this feature used the browser's on-device Translator API. It was replaced because per-text-node translation cannot produce a sentence: the hero came back as word salad and one-word nav labels were translated in the wrong sense ("Features" became "facial features" in Russian). - **2026-06-19**: Landing page: instrument ticker is now a single continuous live line driven by real Yahoo Finance quotes through a public, allow-listed quote endpoint (refreshes periodically). Feature grid expanded to nine cards (added "Benchmark vs the market"). "How it works" condensed to three steps. Hero gained four more live KPI chips (Total Return, Yield on Cost, Today's P&L, vs NASDAQ 100). Accessibility and performance pass: corrected heading order, explicit image dimensions, asynchronous web-font loading, deferred analytics off the critical path, and minified landing CSS. - **2026-05-13**: Landing page redesign: animated hero with floating KPI chips, alternating image/content split sections with 3D tilt screenshots, bento "Who it's for" grid, broker-style instrument ticker carousel (7 categories with sparklines), staggered scroll-reveal animations and counter-animated hero stats. Refreshed JSON-LD with Organization, Person, HowTo, BreadcrumbList and ItemList schemas. AI search hints added (`ai:summary`, `ai:audience`, ``). - **2026-05-12**: Markets & Candlestick Charts section added to landing page, and a Holdings Performance image slot. - **2026-04-01**: Initial public release.
