The Impossible Gold — Optimisation Settings
The Impossible Gold works out of the box — attach to XAUUSD M5 and trade. The v2.0 defaults are the genetically optimised values (36,375+ passes, Jan 2023 – Apr 2026, OHLC 1-min). No separate .set file is needed for standard accounts.
For prop firm accounts, pre-tuned .set files are available with risk, Shield, and daily loss caps configured for each firm's rules. For questions or .set file requests, leave a comment below or send a private message.

⚠️ IMPORTANT
These settings are optimised for standard accounts and are not suitable for prop firm accounts out of the box. Prop firms have specific rules for daily loss limits, maximum drawdown, and leverage that require dedicated .set files and configuration.
- Always test on a demo account for at least 2–4 weeks before running on any live or funded account
- For prop firm settings, see the Prop Firm Settings Guide for firm-specific configuration and guidance
- Past performance and backtest results do not guarantee future results
- The developer is not responsible for any losses incurred on funded or personal accounts

Optimised Set File
v2.0 is a full genetic re-optimisation. The v1 defaults used SL=25 which was too tight for Gold's intraday volatility — normal noise frequently hit the stop before the trade could develop. v2 widens SL to 55, giving trades room to survive volatility while the trailing stop (TrailingStart=15, TrailingStep=20) locks partial profits as price moves.
What changed from v1 to v2.0 (11 parameters):
| Parameter | v1 | v2 | Why |
|---|---|---|---|
| LookbackBars | 16 | 36 | Wider consolidation window (3 hours vs 80 min) — catches higher-quality breakouts |
| BufferPips | 1.5 | 2.5 | More buffer above/below range — fewer false breakouts |
| MinRangePips | 5 | 20 | Only trades ranges ≥$2.00 on Gold — filters noise |
| MinScoreToTrade | 50 | 60 | Higher confidence threshold — fewer but higher conviction entries |
| SessionStart | 10 | 2 | Catches Asian session breakouts (02:00 GMT) |
| SessionEnd | 20 | 19 | Stops 1 hour earlier — avoids thin late-session liquidity |
| BlockWednesday | false | true | Wednesday net-losing across ALL top 8 optimisation results |
| SL_Pips | 25 | 55 | Wider SL gives trades breathing room — DD and Sharpe both improve |
| SpreadMultiplier | 3 | 5 | Wider spread buffer for EnforceMinStops at order placement |
| TrailingStep | 2 | 20 | Genetically optimised — SL trails 20 pips behind price once trailing starts |
| MaxTradesPerDay | 5 | 10 | More opportunities during high-volatility sessions |
SpreadMultiplier and Trailing Stop: SpreadMultiplier=5 only affects the EnforceMinStops() function at initial order placement — it ensures SL/TP are far enough from entry to satisfy broker minimum distance requirements. It does not affect the trailing stop. The trailing stop function uses the broker's SYMBOL_TRADE_STOPS_LEVEL (typically 0 on Gold), so trailing works identically on backtest and live.
Every trade has three possible outcomes:
| Outcome | When | Result (0.01 lot) |
|---|---|---|
| Full SL | Price reverses before trailing starts | -$5.50 (55 pips) |
| Trailing Exit | Trailing engages, then price reverses | Variable partial win |
| Full TP | Price reaches 300 pips | +$30.00 |
Every Tick validation (Q1 2026): +$109,486 on $100K with only 3.6% gap from OHLC backtests. 63.2% win rate, PF 1.18. Trailing stop engages consistently on both backtest and live.
