EPSI Multi SET Strategy

Breakout strategy converted from the original MQL4 expert e-PSI@MultiSET. It watches each candle and enters when price moves a specified distance from the open. Positions use take-profit and stop-loss levels and trades are only allowed during a user-defined time window.

Details

  • Entry Criteria:
    • Long: High - Open >= MinDistance
    • Short: Open - Low >= MinDistance
  • Long/Short: Both
  • Exit Criteria: TakeProfit or StopLoss
  • Stops: Yes
  • Default Values:
    • MinDistance = 20
    • TakeProfit = 20
    • StopLoss = 200
    • CandleType = TimeSpan.FromHours(1).TimeFrame()
    • OpenHour = 2
    • CloseHour = 20
  • Filters:
    • Category: Breakout
    • Direction: Both
    • Indicators: None
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: Intraday
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
