The Impossible Gold — Live-Tuned Set File
EA: The Impossible Gold (FREE)
Signal: mql5.com/en/signals/2365039
The genetic optimiser assumes zero spreads. Real Gold spreads on OANDA ($1-3) caused premature trailing stop-outs and "Invalid stops" errors at the default trail settings. This set file adjusts 3 parameters for smoother live execution. Everything else stays identical to the optimised defaults.
What changed (3 parameters):
| Parameter | Default | Live-Tuned | Why |
|---|---|---|---|
| TrailingStart | 10 | 25 | Prevents trail triggering inside the spread |
| TrailingStep | 2 | 5 | Avoids "Invalid stops" on minimum stop distance |
| MaxTradesPerDay | 5 | 10 | Wider trail exits faster, room for more trades per session |
When to use it:
- Backtesting / Strategy Tester — use defaults (click Reset). Zero-spread environment matches the optimiser.
- Live or demo account — load this set file for real broker conditions.
