Logistic RSI STOCH ROC AO

Strategy applies a logistic map to a selected indicator (AO, ROC, RSI, Stochastic) and trades when the signed standard deviation crosses zero.

Details

  • Entry Criteria: Signed standard deviation crosses above zero.
  • Long/Short: Both directions.
  • Exit Criteria: Signed standard deviation crosses below zero.
  • Stops: None.
  • Default Values:
    • Indicator = LogisticDominance
    • Length = 13
    • LenLd = 5
    • LenRoc = 9
    • LenRsi = 14
    • LenSto = 14
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Oscillator
    • Direction: Both
    • Indicators: AwesomeOscillator, RateOfChange, RelativeStrengthIndex, StochasticOscillator, Highest
    • Stops: No
    • Complexity: Intermediate
    • Timeframe: Intraday (1m)
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
