#Description This optimized GBPUSD H4 strategy introduces a trend filter, only allowing long positions when the 50-period SMA is above the 200-period SMA, and shorts when the 50-period SMA is below the 200-period SMA. The volatility filter ATR(14) > 0.0008 avoids low-volatility noise. Indicator voting uses updated, faster parameters (Stochastic 9,3,3 and Bulls/Bears Power 10), with 3 of 5 signals required for entry. Exits are tightened to 1.5xATR(14) for both target and stop loss. A 1xATR trailing stop, activated at 1.5xATR, locks in gains on moves. This configuration aims for higher-quality, trend-aligned trades and controlled drawdowns.
