STRATEGY SCRIPT · AI ASSISTANT

Describe a strategy. Claude writes the code.

FxBacktest has its own strategy language, FXScript. Write it yourself, or tell the built-in Claude assistant what you trade in plain English and it hands you a working script — then run it over years of real market history in seconds, without touching your open session.

Ask Claude FXSCRIPT ASSISTANT
Buy when the 20 EMA crosses above the 50. Stop 20 pips, target 2R.
Here's an EMA cross strategy sized to 1% risk, with the stop 20 pips away and the target at 2R. The lengths, stop and target are inputs, so you can tune them from the settings panel without editing a line.

Only trade between 07:00 and 16:00 UTC.
Move the stop to break-even once the trade is 1R in profit.
Only take longs while the H4 trend is up.

Illustrative example — hypothetical result, not real or guaranteed performance. Every run opens the same full analytics report your manual sessions get.

Written for you

Say it in plain English and Claude returns FXScript, drops it in the editor, and explains it. One undo puts your own code back.

The chart's own math

48 indicators, higher timeframes, spread and commission — the script calls the exact functions the chart draws with, so a scripted result cannot drift from a manual one.

Tunable without code

Every input() becomes a labeled field as you type it. Change the stop, the target or a length and re-run — no editing, no guessing.

Honest exits

When a candle touches both your stop and your target, finer timeframes decide which came first — instead of the backtest quietly picking the flattering one.

PROP FIRM PREP

Practice a prop firm challenge before you pay

Set the firm's exact rules and run the whole evaluation on real market history — a live tracker follows your phase, drawdown and target bar by bar, then a result screen tells you if you passed. All before you spend a cent on a real challenge.

FAQ

Forex backtesting questions.

Quick answers to what most traders ask before they start backtesting.

What is forex backtesting? +

Forex backtesting is replaying historical price data and placing trades as if you were trading live, so you can measure how a strategy would have performed without risking real money. A good backtester gives you bar-by-bar replay, realistic spreads and commissions, and stats like win rate, drawdown, and expectancy across the sample.

Is FxBacktest really free? +

Yes. The Free plan never expires — all 93 instruments, all seven timeframes, full trade execution, the full session report, and three saved sessions in your journal. No credit card required. Pro and Ultra unlock more indicators, deeper analytics, and a larger journal, but the core backtesting loop is free forever.

Do I need to install anything or connect a broker? +

No. FxBacktest runs entirely in your browser — no download, no plugin, no MetaTrader, no broker account. Historical data is bundled with the app, so you can open a chart and start placing trades within seconds of registering.

Can I backtest forex online without downloading anything? +

Yes. FxBacktest is an online forex backtesting tool that runs on the site itself — open it in any browser, pick an instrument, and the historical charts load straight into the page. There is no installer, no plugin and no MetaTrader, so it behaves the same on Windows, macOS, Linux and ChromeOS.

Is there a forex backtesting app for Android or iPhone? +

There is no separate app to install from the Play Store or App Store — FxBacktest runs in your phone’s browser instead. Open the site on Android or iPhone and the chart replay, trade panel and session report all resize for a phone screen. You can add it to your home screen so it opens like an app.

How many trades should I backtest before trusting a forex strategy? +

A small test of 20 trades can reveal obvious execution problems, but a serious review normally needs 100 or more trades across different market conditions. More important than the exact number is that the sample includes wins, losses, slow periods, news volatility, and at least one uncomfortable drawdown.

Is manual forex backtesting better than automated backtesting? +

Manual backtesting is better for discretionary decisions, price action reading, and building screen time. Automated backtesting is better for strict rule sets that a computer can execute without interpretation. Many traders use both — manual testing to understand the setup, then automation to check it at scale.

Can a profitable backtest guarantee live trading profits? +

No. A backtest shows how a plan behaved on historical data. Live results still depend on spreads, slippage, psychology, execution speed, broker conditions, and whether the market regime changes. A solid backtest builds confidence and discipline, but it is a starting line, not a finish line.
