Long Term Profitable Swing Strategy

This strategy enters long when a fast EMA crosses above a slow EMA and the RSI is above a specified threshold. Exits occur when price hits ATR-based stop loss or take profit levels.

Details

  • Entry Criteria:
    • Long: fast EMA crosses above slow EMA and RSI > threshold.
  • Long/Short: Long only.
  • Exit Criteria:
    • Price reaches ATR-based stop loss or take profit.
  • Stops: ATR multiples for stop loss and take profit.
  • Default Values:
    • FastEmaLength = 16
    • SlowEmaLength = 30
    • RsiLength = 9
    • AtrLength = 21
    • RsiThreshold = 50
    • AtrStopMult = 8
    • AtrTpMult = 11
  • Filters:
    • Category: Trend following
    • Direction: Long
    • Indicators: EMA, RSI, ATR
    • Stops: Yes
    • Complexity: Low
    • Timeframe: Any
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
