MT5 Backtester
A full client-side backtesting engine that simulates MT5 trade execution on historical data. Test strategies with real commissions, swap, margin, and all the tools you use live, entirely in your browser, entirely free.
MT5-accurate execution
Hedging & netting, 10 margin modes, margin call + stop-out, and correct bid/ask-side SL/TP, all matching real MT5 behavior.
Real-world costs
Per-lot commissions, 6 swap modes, triple-swap-day, and cross-currency conversion so your P&L reflects actual trading costs.
Full workspace
Grids, risk manager, smart orders, ghost orders, and position stops all work in the backtest, same tools as live.
Everything the engine can do
The backtester mirrors MT5 execution so your results translate to live trading. Here is what is included.

10 margin calculation modes
Forex, CFD, CFDLeverage, CFDIndex, Futures, Exchange Futures, Exchange Stocks, Exchange Options, Forex No Leverage.

Commission & swap
Per-lot commissions, 6 overnight swap modes (points, currency deposit/symbol/margin, interest current/open), and triple-swap-day.
Currency conversion
Cross-currency profit and margin conversion via live tick data so multi-currency accounts are accurate.
