Backtest Performance Results

The EURUSD backtest from January 1999 to June 2025 produced $56,235 net profit from a $2,500 deposit — a profit factor of 1.31 across 24,453 trades at 77.64% win rate. Maximal drawdown reached 20.08% relative, with a dollar figure of $2,107 against a growing balance.

The USDJPY 26-year backtest returned $48,961 net profit from $2,500 with the lowest maximal drawdown of all tested pairs — just 5.70%. Win rate held at 81.26% across 17,752 trades, with a profit factor of 1.29.

The GBPUSD backtest (Build 1141, 26 years) returned $143,752 net profit from $2,500, with a maximal drawdown of 3.42% and win rate of 82.66% across 67,711 trades. Profit factor was 1.21 — lower than EURUSD and USDCHF, which is consistent with GBPUSD’s historically wider spread environment.

The USDCHF backtest produced the strongest profit factor of all four pairs at 1.60, with $63,173 net profit from $2,500 and the lowest maximal drawdown — just 3.10%. Win rate reached 80.58% across 24,277 trades.

The EURUSD run recorded a 20.08% relative drawdown — the highest across all four pairs. This occurred during extended choppy periods where multiple signals opened simultaneously before the trend resolved. Control this by setting Max_Orders_Total to 3 or lower, keeping capital at $2,500+ per pair, and monitoring open positions during high-impact news. Realistic outcomes range from 15–25% drawdown in worst-case consolidation phases. The other three pairs held below 6% maximal drawdown across the same 26-year window.

Backtest results differ from live trading due to slippage and spread variation. All four runs used a 10-pip spread and 90% modeling quality. Demo validation recommended 60+ days before live deployment.

How It Works

Strategy: Three independent M15 signals trade EURUSD, GBPUSD, USDJPY, and USDCHF — each exploiting short-term price exhaustion and mean reversion on 15-minute bars.

Entry: Each signal fires independently based on its own trigger logic; AutoGMT offset aligns entry windows to broker server time automatically.

Exit: Trades close at fixed take profit or stop loss levels; Friday exit closes all positions before weekend gap risk at hour 20.

Risk Control: AutoMM scales lot size to balance (0.5% default); Max_Orders_Total caps simultaneous open trades at 5 across all signals.

✅ Best conditions: Low-spread ECN broker (below 2.5 pips) • Stable VPS with consistent GMT sync • Account balance $2,500+ per active pair

⚠️ Caution: Spreads above 2.5 pips trigger the MaxSpread filter and block entries • High-volatility news events with no news filter active
