PoundYen Trader EA — GBP/JPY Scalping Robot for MT4

PoundYen Trader EA is a dedicated GBP/JPY scalping system for MetaTrader 4, trading the M15 timeframe with a rules-based entry and fixed risk model. A 5-year backtest (2020–Feb 2025) using real-tick 100% modeling quality recorded an 81.08% win rate, profit factor of 3.88, and maximum balance drawdown of 1.68% — results that warrant serious evaluation before live deployment.

Performance Results

The backtest ran from September 2020 to February 2025 using real-tick data at 100% modeling quality — the highest fidelity available in MT4’s Strategy Tester. Over 1,052 trades, the EA recorded an 81.08% win rate, profit factor of 3.88, and a maximum balance drawdown of just 1.68%. The recovery factor of 73.83 means the system recovered losses at roughly 74x the speed they occurred — a ratio indicating the edge is consistent, not concentrated in a few lucky trades.

The Quant Analyzer cross-examination of the same data confirms a 251.3% CAGR, 5.48% drawdown, and an SQN Score of 12.39 — a score above 7 is considered “Holy Grail” quality by system development standards. The R Expectancy of 0.58R across 1,052 trades means the edge held consistently across varied GBP/JPY conditions including the 2022 yen crisis and 2023 volatility spikes.

The maximum consecutive loss sequence was 3 trades, and the worst single loss reached -$182,009 at a late-period balance scale — representing under 2% of account equity at that point. With 2% fixed risk, a sustained losing streak of 10 trades would reduce a $10,000 account by approximately $1,800 before the system historically recovered. No live account data exists yet. A 90-day demo test is mandatory before committing real capital — backtest conditions assume zero slippage and ideal execution, which live brokers do not guarantee.

Backtest results from September 2020 to February 2025, 100% real-tick modeling quality. Live trading introduces slippage, spread variation, and execution latency not present in backtests. Demo validation mandatory 90+ days before live deployment.

How It Works

Strategy: Momentum scalping on GBP/JPY M15 — exploits short-term directional bursts in a pair known for sharp, liquid moves driven by Bank of Japan policy divergence.

Entry: Trigger conditions fire on M15 price action confirmation — both long (83.09% win) and short (76.69% win) directions traded.

Exit: Fixed take-profit and stop-loss levels per trade; maximum 3 consecutive losses recorded in full 5-year test period.

Risk Control: Fixed 2% balance risk per trade with automatic lot scaling — max 5 simultaneous positions, up to 300 lots exposure at peak balance scale.

✅ Best conditions: Active London/Tokyo overlap sessions • Trending GBP/JPY with clear directional momentum • Low-spread ECN broker execution

⚠️ Caution: High-impact BoJ or BoE news events • Thin liquidity weekend gaps • Brokers with variable spreads exceeding 3 pips on GBP/JPY

Who Should Use This EA

✅ Ideal for:

• Accounts of $1,000 or more where 2% fixed risk keeps individual losses under $20 at entry scale
• Traders with ECN broker access and GBP/JPY spreads consistently under 3 pips

✅ Best results when:

• Running on a VPS with stable connectivity during London and Tokyo session overlap hours
• News filters are applied manually around BoJ and BoE interest rate decisions
