Strategy Overview
The EA identifies overbought and oversold conditions using Bollinger Bands. When price closes outside the bands and forms a reversal pin bar, the EA prepares a trade. To avoid false signals, the following confirmation filters are applied:
-
Trend Filter (EMA200 on H1) – Trades only in the direction of the higher timeframe trend.
-
Volatility Filter (Minimum ATR) – Avoids trading during low‑volatility or ranging markets.
-
Spread & Session Filters – Prevents trading during unfavorable market conditions.
Entry Logic:
-
Long: Price closes below the lower Bollinger Band and a bullish pin bar is formed.
-
Short: Price closes above the upper Bollinger Band and a bearish pin bar is formed.
Risk- and Moneymanagement
The EA uses ATR (Average True Range) to dynamically adjust stop‑loss and take‑profit levels to current market volatility. This ensures that risk per trade remains proportional to market conditions.
-
Stop Loss: X × ATR
-
Take Profit: X × ATR (Risk/Reward > 1:3)
-
Position Sizing: Fixed lot or percentage risk per trade (user selectable)
-
Trailing Stop: Activates after price moves favorably by a user‑defined distance, securing profits as the trend continues.

Important notes
-
Regular monitoring and occasional parameter adjustments are recommended.
-
We only provide trading tools and do not give financial advice. You trade at your own risk.
-
Always test on a demo account for at least 2–4 weeks before going live.
-
Past performance does not guarantee future profits. Only trade with risk capital.
- The EA and its parameters are regularly adjusted to current market conditions. Therefore, long-term performance is not meaningful—the gold market of 2026 is different from that of 2025 or 2024.
