Key Benefits

• ✅ Gap-Specific Entry: Trades only verified weekend gap events above 50 points — low trade frequency means each position carries meaningful edge, not noise.
• ✅ Directional Bias: Long positions win at 78.18% vs short at 45.45% on GBPJPY — strategy captures asymmetric gap-fill behavior, but short-side underperformance limits purely bearish gap setups. Compare EA strategies
• ✅ Trailing Exit Logic: Candle-extreme trailing activates immediately at open, locking gains progressively — means partial profit is secured even when full gap closure doesn’t complete.
• ✅ Automatic Position Sizing: Lot scales with free margin at 2.0 lots per $1,000 — eliminates manual recalculation, but compounds drawdown on undercapitalized accounts.

Gap Professional EA Performance

Two independent GBPJPY H1 backtests covering 2018–2020 are available below. Neither represents a live account — there is no verified Myfxbook signal for this EA.

Backtest 1 (Every Tick, 90% modeling quality): $100 starting capital, 77 trades, profit factor 3.47, peak drawdown 35.25%, win rate 68.83%, tested January 2018 to February 2020.

Backtest 2 (same period, different parameter set): $100 starting capital, 95 trades, profit factor 3.29, peak drawdown 26.91% maximal, relative drawdown 56.14%, win rate 56.1%.

Performance Snapshot

Relative drawdown above 56% across both parameter sets signals a structural risk to small accounts. The EA’s automatic lot sizing (2.0 lots per $1,000 free margin) means a $100 account absorbs the full force of any adverse gap — the same mechanism that drives high returns also concentrates loss. This is a structural characteristic of the auto-sizing formula, not a configuration error.

Reducing the lot-per-margin ratio from 2.0 to 0.5–1.0 (via the “Lot for 1000 units of free margin” parameter) directly limits position size relative to account equity. Post-mitigation outcome at lower lot settings is not documented in available backtest data — treat as requiring your own demo testing before live deployment.

Adding a spread cap via “Max spread when opening points” filters low-liquidity gap opens; the default setting of 0 means the EA trades regardless of spread at the Sunday open, which is the single highest-spread window of the trading week.

A 2018–2020 backtest at 90% modeling quality confirms gap-fill behavior — it excludes live spread conditions at Sunday open, slippage, and broker-specific gap sizing that will affect real results.

How Gap Professional EA Works

Mechanism: GBPJPY frequently opens Monday with a price gap versus Friday’s close, driven by weekend news and liquidity absence. Gap Professional enters a position targeting gap closure — the statistical tendency for price to return toward the prior close — on the H1 chart. The strategy exploits a documented GBPJPY behavioral pattern: gaps above 50 points close at significantly higher rates than smaller gaps, providing a size-qualified entry filter rather than trading every open.

Signal Trigger: Gap size must exceed 50 points at market open. Entry direction is toward the gap close level. The tick criterion is set to 0 (disabled) by default, meaning timing within the gap candle is not filtered by tick activity.

Position Close: Trailing stop tracks candle extremes, activating immediately from position open. Take profit is set at 0.8× the gap size (coefficient 0.8), capturing a partial gap fill rather than requiring full closure. This combination means the EA locks partial gains as price moves toward closure and exits short of the full gap distance.

Exposure Limits: Initial stop loss is 150 points. Lot sizing scales automatically at 2.0 lots per $1,000 free margin — there is no basket or maximum simultaneous positions control documented in the parameter set. On a single-pair strategy this means one open trade at a time, but the stop distance of 150 points at aggressive lot sizes creates material per-trade risk.

✅ Optimal conditions: Clean Monday gap above 50 points on GBPJPY with tight Sunday open spread; low-volatility gap events where price moves steadily toward closure rather than reversing.

⚠️ Avoid when: Major news event over the weekend that causes a gap in the opposite direction to expected closure (gap extension rather than fill); brokers with wide Sunday open spreads that trigger stop loss before gap fill initiates.

Recommended Settings

Who Should Use Gap Professional EA

• ✅ Running MT4 on a VPS that stays online through Sunday’s market open — missing the gap window means missing the only trade of the week.
• ✅ Trading with a broker that shows consistent GBPJPY weekend gaps — gap frequency and size vary significantly by broker; optimization per your broker’s historical data is required before live use.
• ✅ Comfortable sizing the lot-per-margin ratio conservatively — the default 2.0 lots per $1,000 produced 56%+ relative drawdown in backtest; buyers who cannot tolerate that exposure need to reduce this setting before going live.
• ✅ Prepared to demo test for at least 60–90 days — the strategy trades at most once per week, meaning a meaningful sample requires a full market cycle of gap events under live spread conditions.
