KST Strategy Skyrexio

The strategy goes long when the Know Sure Thing (KST) indicator crosses above its signal while price trades above a chosen moving average and the Alligator jaw. A choppiness index filter can disable entries in ranging markets. Positions are closed using ATR-based stop-loss and take-profit levels.

  • Entry Criteria: KST crosses above signal, price above filter MA and Alligator jaw, choppiness below threshold.
  • Exit Criteria: Price hits ATR stop-loss or ATR take-profit.
  • Indicators: KST, ATR, Moving Average, Alligator jaw, Choppiness Index.

Parameters

  • CandleType – candle timeframe.
  • AtrStopLoss – ATR multiplier for stop-loss.
  • AtrTakeProfit – ATR multiplier for take-profit.
  • FilterMaType – type of trend filter MA.
  • FilterMaLength – length of trend filter MA.
  • EnableChopFilter – enable choppiness filter.
  • ChopThreshold – choppiness index threshold.
  • ChopLength – choppiness index period.
  • RocLen1..4 – ROC lengths for KST.
  • SmaLen1..4 – SMA lengths for KST.
  • SignalLength – KST signal SMA length.
