All Divergences Strategy

The All Divergences strategy looks for bullish and bearish RSI divergences filtered by a moving average trend. A long position is opened when price makes a lower low while RSI forms a higher low above the moving average. A short position is opened when price makes a higher high while RSI forms a lower high below the moving average. Optional stop-loss and take-profit protection can automatically close positions, and a moving average risk control exits after several closes against the trend.

Details

  • Entry Criteria:
    • Price relative to moving average defines trend.
    • Long: price makes lower low, RSI higher low, price above MA.
    • Short: price makes higher high, RSI lower high, price below MA.
  • Long/Short: Both sides.
  • Exit Criteria:
    • Opposite signal or MA risk exit.
  • Stops: Optional stop-loss and take-profit.
  • Default Values:
    • MaLength = 50
    • RsiLength = 14
    • MaRiskCandles = 3
    • UseProtection = False
  • Filters:
    • Category: Divergence
    • Direction: Both
    • Indicators: RSI, Moving Average
    • Stops: Optional
    • Complexity: Medium
    • Timeframe: Any
    • Seasonality: No
    • Neural networks: No
    • Divergence: Yes
    • Risk level: Medium
