Adaptive Cyber Cycle Strategy

This strategy utilizes the Adaptive Cyber Cycle oscillator by John Ehlers. It calculates a smoothed price cycle and uses the previous value as a trigger line. A long position is opened when the cycle crosses above the trigger, and a short position is opened on a downward cross.

Details

  • Entry Criteria:
    • Long: cycle > previous cycle.
    • Short: cycle < previous cycle.
  • Long/Short: Both.
  • Exit Criteria:
    • Opposite signal closes and reverses the position.
  • Stops: None by default; protection can be enabled separately.
  • Default Values:
    • Alpha = 0.07
    • Candle Type = 1-minute time frame
  • Filters:
    • Category: Trend following
    • Direction: Both
    • Indicators: Adaptive Cyber Cycle
    • Stops: Optional
    • Complexity: Moderate
    • Timeframe: Intraday
