ALMA Optimized-Strategie

Diese Strategie kombiniert eine Arnaud Legoux Moving Average mit einem langfristigen EMA, ADX, RSI und Bollinger-Bändern. Ein ATR-basierter Filter stellt ausreichende Volatilität sicher. Positionen verwenden ATR-Multiplikatoren für Stop-Loss und Take-Profit, mit einem optionalen zeitbasierten Ausstieg.

Details

  • Einstiegskriterien:
    • Long: ATR über dem Schwellenwert, Schlusskurs über EMA und ALMA, RSI > 30, ADX > 30, Schlusskurs unter dem oberen Bollinger-Band und Abkühlzeit abgelaufen.
    • Short: Schlusskurs kreuzt unter die schnelle EMA unter demselben Volatilitätsfilter.
  • Ausstiegskriterien:
    • Stop-Loss oder Take-Profit basierend auf ATR-Multiplikatoren.
    • Optionaler zeitbasierter Ausstieg in Bars.
  • Standardwerte:
    • Schneller EMA = 20.
    • ATR-Länge = 14.
    • EMA-Länge = 72.
    • ADX-Länge = 10.
    • RSI-Länge = 14.
    • Abkühlzeit = 7 Bars.
    • Bollinger-Multiplikator = 3.0.
    • Stop-ATR-Multiplikator = 5.0.
    • Take-ATR-Multiplikator = 4.0.
    • Zeitausstieg = 0.
    • Minimaler ATR = 0.005.
  • Filter:
    • Kategorie: Trend + Momentum
    • Richtung: Beide
    • Indikatoren: EMA, ALMA, ADX, RSI, ATR, Bollinger Bands
    • Stops: ATR-basiert
    • Komplexität: Moderat
