Stochastic Three Periods

The Stochastic Three Periods strategy aligns fast stochastic signals with confirmation from two higher timeframes. Trades are opened when the fast oscillator crosses while both higher timeframes agree.

Details

  • Entry Criteria: Fast %K crosses %D with opposite reading ShiftEntrance bars ago; both higher timeframe stochastics show %K above %D; close price must move in signal direction.
  • Long/Short: Both.
  • Exit Criteria: Opposite fast stochastic cross measured on previous candle.
  • Stops: Fixed stop-loss and take-profit in points via StartProtection.
  • Default Values:
    • CandleType1 = 5m
    • CandleType2 = 15m
    • CandleType3 = 30m
    • KPeriod1 = 5
    • KPeriod2 = 5
    • KPeriod3 = 5
    • KExitPeriod = 5
    • ShiftEntrance = 3
    • TakeProfitPoints = 30
    • StopLossPoints = 10
  • Filters:
    • Category: Oscillator
    • Direction: Both
    • Indicators: Stochastic
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: Intraday
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
