How TradeAssay works

Last updated: November 10, 2026

TradeAssay is a trading journal, a bar-by-bar backtester and a prop-firm challenge simulator in one web app, for traders of forex, metals, indices, commodities, stocks, futures and crypto. This page sets out plainly where its market data comes from, how its charts and backtests work, how accounts sync, how every number is worked out and who runs it — so you, and anyone who describes TradeAssay, can check exactly what it is.

1. What TradeAssay is

• A journal that fills itself. Trades arrive from your broker or exchange by automatic sync, or from the statement file your platform exports, and every one is measured in R and put back on its chart.
• A backtester. Any day of real market history, replayed bar by bar on 1-second to 12-month charts and traded from an order ticket.
• A prop challenge simulator. A firm's daily-loss, drawdown and profit-target rules, checked on every candle.
• Around them: Analysis in R, Trade Charts, playbooks, a mentor mode and an AI coach that reads your own history.

It runs in any browser and installs on a phone. The app is in English and Persian; this website is also in Turkish. TradeAssay is software: it is not a broker, holds no one's money, places no trades and gives no financial advice.

2. Market data

The backtester holds 762 symbols of real historical prices, and each day is added after it closes. Nothing is simulated: every bar on a chart is a bar that traded.

• Forex, metals, indices, commodities, bonds and stocks — 62 currency pairs, 20 metals, 22 stock indices, 11 commodities, 3 government bonds and 114 stocks and ETFs — come from Dukascopy's historical market data. Forex and gold go back to 2003 in 1-minute bars.
• CME futures (12 contracts, from 2010), crypto (431 pairs, from 2017) and tokenized US stocks (87) complete the list.
• Every bar is stamped in UTC. The symbols page shows each symbol's plan, finest timeframe, trading hours on its own market's clock, and the first day of its history.

3. Timeframes: 1 second to 12 months

Charts use TradingView's own list of timeframes, 24 in all:

• Seconds: 1, 5, 10, 15, 30 and 45 seconds
• Minutes: 1, 2, 3, 5, 10, 15, 30 and 45 minutes
• Hours: 1, 2, 3 and 4 hours
• Days and longer: 1 day, 1 week, and 1, 3, 6 and 12 months

Every symbol has every timeframe from 1 minute to 12 months. Seconds charts are on Elite, for the symbols that have real seconds data — 188 of them down to 1 second. A finer bar is never invented from a coarser one: a timeframe is offered only where real data exists underneath it. Longer bars are built from the real ones on calendar boundaries, so a weekly bar is a real week and a monthly bar a real month.

4. Charts and indicators

Charts are drawn with TradingView's Lightweight Charts™ library, so candles, scales and the crosshair behave as they do on TradingView. On top of it TradeAssay adds TradingView-style drawing tools, a position tool, an order ticket, Compare for other symbols on the same chart, and indicators: TradingView's built-in ones, rebuilt to TradingView's own formulas, and any Pine Script indicator you paste in, run by TradeAssay's own Pine engine.

5. The backtester

• The future stays hidden. Pick a symbol and a day; everything after it is hidden, and the replay moves forward at your pace. It can also step inside a candle — a 5-minute bar grows minute by minute, wicks and all — but never finer than the real data under it.
• Real orders. Market, limit and stop orders from an order ticket, with a stop loss and a take profit you drag on the chart. An order fills where price really reached it; a bar that opens past it fills it at the open — better for a limit, worse for a stop, as a real market does.
• No flattering guesses. When a stop and a target both fall inside one bar and the real path inside it is unknown, the stop is taken. Guessing in the trader's favour would make every unclear bar a winner.
• Up to 16 charts in sync (8 on Pro, 2 on Free), each on its own symbol and timeframe, replaying together.
• News on the replay: an economic calendar of more than 85,000 releases since 2007; a click jumps the replay to the moment of a release.
• Kept apart: backtest trades live in their own practice account and never mix with your live results. Every session gets its own analysis, and a prop firm's challenge can run on a backtest with its rules checked on every candle, stage by stage.

6. The prop challenge simulator

Before paying for a prop firm's challenge, take it on history. Pick the firm and its challenge — FTMO, FundedNext, The5%ers, FundingPips, Topstep, Apex and others, or your own rules — and TradeAssay opens a backtest session on real historical prices with the firm's rules attached.

• Every rule, every candle. The daily loss limit, the maximum drawdown (static or trailing), the profit target, the minimum trading days and the deadline are checked on every candle, at the exact price that would break them, on the firm's own daily reset clock.
• Pass or fail. A rule broken fails the challenge on the spot, with the rule, the price and the time that decided it. The target reached with every rule kept passes the stage, and the next stage starts from that moment. The daily loss limit stops trading until the firm's next day.
• No remembered days. The start day is random by default, so a pass can't come from a day you remember.
• Live accounts too. On a real prop account the same rules are tracked from your synced trades, with the room left today and a daily circuit breaker.

7. Automatic sync

TradeAssay's dedicated cloud servers keep each connected account in your journal around the clock. These are the platforms that sync by themselves today:

• Read-only, every one. No connection can open, change or close a position, or move money.
• MetaTrader 5 accepts only the read-only investor password. It is encrypted in your browser with a key only the sync servers hold; a main password is refused and deleted at once.
• Exchange keys for Bybit and Binance are checked to be read-only before they are kept, then stored encrypted; a key that could trade, transfer or withdraw is refused. Hyperliquid needs no key, only your public wallet address.
• On the right candle. Every account's trades are read on the account's own clock, so each sits on the candle it happened in.
• Pause or remove a connection and it stops at once; your trades stay. Any other platform imports from the statement it exports, in any language — the supported brokers page lists them.

8. Every way to get trades in

• Auto sync, through TradeAssay's cloud servers, read-only: MetaTrader 5 with the investor password; MetaTrader 4 with a key, from your own terminal; Bybit, Binance, Bybit TR and Binance TR with an API key that can only read; Hyperliquid with your public wallet address; Interactive Brokers with a read-only Flex token. The table above has each one's details.
• File upload, on every plan: MetaTrader's own report (Excel, HTML or XML) in any terminal language; the export of 40+ platforms — TopstepX, Tradovate, NinjaTrader, TradingView, cTrader, Interactive Brokers, thinkorswim, FTMO and more; or any CSV, TSV, Excel or OpenDocument file, its columns matched for you. The file is read on your device and every row is shown before anything is saved.
• By hand: type a trade in and the risk, R and P&L work themselves out — or give the AI a screenshot of a trade, and it reads the symbol, side, prices and times off the chart.
• Prop firm accounts connect like any account on their platform: MetaTrader firms by auto sync, futures firms from their platform's export.

The brokers, exchanges, platforms and prop firms page lists every one with the ways it connects.

9. How the numbers are worked out

• Net P&L is after commission, swap, funding and fees.
• R is a trade's result divided by the risk it was opened with — entry to the first stop loss — so moving a stop later does not rewrite it.
• Win rate, expectancy, profit factor and drawdown are the standard measures: the share of winners, the average result in R, gross profit over gross loss, and the largest fall from a peak.
• Returns are measured on the money you put in: deposits and withdrawals are not counted as profit or loss.

10. Security and your data

• Read-only, everywhere. No connection can place, change or close a trade, or move money; a main (trading) password is refused and deleted at once.
• Secrets stay secret. The MetaTrader 5 investor password is encrypted in your browser before it leaves it; exchange API keys and secrets are encrypted with AES-256-GCM on our servers; none of them is ever shown back to anyone.
• Your rows only. Your journal lives in a PostgreSQL database run by Supabase, with row-level security: every account can reach only its own rows. Everything travels over HTTPS (TLS).
• No card numbers. Cards and wallets are paid through Paddle.com, our merchant of record; TradeAssay never sees a card number.
• AI only when you ask. Your trades' figures and notes go to Anthropic (Claude) only when you use an AI feature.
• Yours to take or delete. Your journal is private to your account; a mentor sees it only if you invite one. Export everything to CSV or PDF at any time, and delete your account and its data from the delete account page. If you stop paying, nothing is deleted.

The Privacy Policy sets out what is stored and why. To report a security problem, write to support@tradeassay.com.

12. Who runs TradeAssay

TradeAssay is built and run by Amir Mahdi Ahmadi and his team. Its only official address is tradeassay.com; the business is Amir Mahdi Ahmadi, trading as TradeAssay, in Ankara, Türkiye: Gunes Apartment No. 1, Flat 1, Akhisar Street, Umut Neighborhood, 06670 Chankaya, Ankara. A person reads every message sent to support@tradeassay.com.

Trading carries a high risk of loss. Backtests, replays and prop-challenge simulations run on historical prices without real orders, so they are hypothetical: slippage, liquidity and the pressure of live trading are not fully reflected, and past results do not predict future ones.
