Manual backtesting software

Replay the market bar by bar and trade it the way you would live, on up to 20+ years of 1-minute data across forex, futures, crypto, stocks and indices. It runs in your browser, and forex and metals are free.

Manual backtesting with bar replay

Replay the chart, take the trades your strategy calls for, and see what it would have made.

Bar replay

Replay any chart bar by bar and trade it as it unfolds, with stops, targets and risk-based sizing. The future stays hidden until you press Play, so it plays like a live market.

How the replay works

Prop firm challenge mode

Backtest under a prop firm's real rules: profit target, daily loss and trailing drawdown are tracked as you trade, and the run ends in a pass or fail.

Describe your rules to AI Chat and it tests the strategy for you on years of 1-minute history, with the stats and every trade.

• Partial close & scale-out on any position
• Multiple take-profit levels

• Realistic spread and commission simulation

Advanced Charting & Indicators

Hundreds of built-in indicators grouped by category — moving averages, RSI, MACD, Bollinger Bands, volume tools, session markers and more. Missing one? Write it in Python in the built-in editor, or describe it and let the AI write it for you.

• 400+ built-in indicators, organised by category
• Custom Python indicators — hand-written or AI-generated
• Drawing-tool templates & custom line styles
• Multi-timeframe analysis on one screen

Multi-Chart Layouts & Syncing

Never lose context again. Split your screen into multiple panes and analyse the same asset across timeframes simultaneously. Synchronized crosshairs mean every chart moves together — so you see the full picture at a glance.

• Split-screen layouts: 2, 3, or 4 panes
• Synchronized time and crosshairs across all charts
• Sync drawings across charts, or unlink one to roam
• Independent indicators per pane

Custom Fees & Slippage

Your backtesting results are only as good as your cost model. Configure exact commission structures, realistic spreads, and per-side fees — so your simulated P&L actually reflects live trading conditions.

• Broker presets, or your own commission and spread
• Fixed spreads, or floating spreads that widen with market conditions
• Flat, percentage, and per-lot fees
• Separate opening and closing fees

Economic News Calendar

Cross-reference your trade results with economic events. See exactly which news releases caused your best and worst performances — and build a data-backed view of which events your strategy handles well or should avoid.

• Full economic event timeline
• Impact level filtering (low / medium / high)
• Enable alerts so you don't trade during major news
• Supports all major forex and macro events
