King of the Night EA — EURGBP & EURUSD M15 Scalper with Sub-9% Drawdown

King of the Night EA is a nighttime scalper for MT4 that targets EURGBP and EURUSD during the low-volatility window between 00:00 and 01:00, exploiting tight mean-reversion conditions when institutional volume is minimal.

Across four backtests on $500–$5,000 starting capital, peak drawdown held between 8.54% and 8.62% with win rates of 92–94% over the January–June 2025 period.

Key Benefits

• ✅ Consistent DD ceiling: Peak drawdown held under 9% across all four tested capital levels ($500–$5,000) — the cost is a strategy that only trades one hour per night, leaving capital idle 23 hours.
• ✅ Nighttime edge: Enters only during the 00:00–01:00 window when spread compression and low volatility favor tight scalps — misses all London/New York session moves entirely.
• ✅ Spread gate: Max spread filter of 30 points blocks entries when broker costs exceed the profit target, preventing low-quality fills from eroding the win rate. Compare EA strategies
• ✅ Scalable capital structure: Dynamic money management at Risk 3 scales lot size proportionally — a $5,000 account runs the same logic as a $500 account, drawdown percentage stays consistent.

King of the Night EA Performance

Four backtests on EURGBP and EURUSD M15, January–June 2025, across $500, $1,000, $2,000, and $5,000 starting capital — all run on ICMarketssc-Demo4, Build 1441.

EURGBP $500: 212 trades, 94.34% win rate, 8.54% peak drawdown, profit factor 54.03.

EURUSD across $1,000, $2,000, and $5,000 starting capital: peak drawdown held within 8.60–8.62% across all three, profit factor 32.45–53.76, win rate 92.57–94.34%.

All four backtests used the “Control points” modeling method — flagged within the MT4 tester itself as a very crude approximation. This means tick-level spread behavior, requotes, and slippage are not simulated; the win rate and drawdown figures reflect idealized fills that live execution will not replicate exactly.

The specific condition that stresses a nighttime scalper is any event that expands spreads beyond 30 points during the 00:00–01:00 window — central bank emergency actions, geopolitical shocks, or illiquidity at Sunday open. The Max Spread Open filter at 30 points is a Controllable safeguard: when spread exceeds the threshold the EA skips the trade entirely.

What the filter cannot do is protect against mid-trade spread spikes on an already-open position. That exposure is Structural — inherent to any scalper with a 5-point take profit target operating in a thin market. Sizing appropriately at Risk 3 with a minimum $500 account is the practical mitigation documented in the backtest configuration.

These figures come from a 6-month control-points backtest — live spread behavior and slippage are not captured and will shift both win rate and drawdown in real trading.

How King of the Night EA Works

Mechanism: King of the Night exploits the directional drift that occurs in EURGBP and EURUSD during the 00:00–01:00 GMT window, when Asian session liquidity thins and price tends to range or make short impulsive moves before the London pre-open. The EA targets these small, predictable displacements with a fixed take-profit scalp structure, exiting before the market regains directional bias.

Signal Trigger: Entry conditions are not publicly documented beyond the trading window constraint (00:00–01:00) and the spread gate (Max Spread Open: 30 points). The EA trades one buy and one sell direction per session (Count Buy: 1, Count Sell: 1).

Position Close: Fixed take profit at 5 points (Take Profit Close: 5). No trailing stop or time-based forced exit is documented in the available configuration.

Exposure Limits: Maximum one buy and one sell position open simultaneously per pair. Spread gate blocks new entries when broker spread exceeds 30 points. Dynamic lot sizing via Money Management at Risk 3 scales position size to account equity.

✅ Optimal conditions: Low-spread ECN environment during 00:00–01:00 GMT; stable overnight macro backdrop with no scheduled high-impact news events; broker with raw spreads on EURGBP and EURUSD below 10 points at session open.

⚠️ Avoid when: Any scheduled high-impact news event falls within or immediately before the 00:00–01:00 window; Sunday session open when spreads on EURGBP routinely widen significantly beyond the 30-point filter.
