Multi Indicator Swing

Swing strategy combining Parabolic SAR, SuperTrend, ADX and volume delta confirmation.

Details

  • Entry Criteria: All enabled indicators agree.
  • Long/Short: Both directions.
  • Exit Criteria: Opposite signal or hitting stop-loss/take-profit.
  • Stops: Optional percentage based levels.
  • Default Values:
    • CandleType = TimeSpan.FromMinutes(2)
    • PsarStart = 0.02m
    • PsarIncrement = 0.02m
    • PsarMaximum = 0.2m
    • AtrPeriod = 10
    • AtrMultiplier = 3m
    • AdxLength = 14
    • AdxThreshold = 25m
    • DeltaLength = 14
    • DeltaSmooth = 3
    • DeltaThreshold = 0.5m
    • StopLossPercent = 2m
    • TakeProfitPercent = 4m
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: PSAR, SuperTrend, ADX, Volume
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: Intraday (2m)
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
