ADX Slope Mean Reversion-Strategie

Die ADX Slope Mean Reversion-Strategie konzentriert sich auf extreme ADX-Werte, um Rückkehrbewegungen auszunutzen. Starke Abweichungen vom Durchschnittsniveau halten selten lange an.

Trades werden ausgelöst, wenn der Indikator weit von seinem Mittelwert abweicht und dann beginnt, sich umzukehren. Sowohl Long- als auch Short-Setups enthalten einen Schutz-Stop.

Geeignet für Swing-Trader, die Oszillationen erwarten; die Strategie schließt die Position, sobald der ADX zum Gleichgewicht zurückkehrt. Startparameter AdxPeriod = 14.

Details

  • Einstiegskriterien: Der Indikator kreuzt zurück in Richtung Mittelwert.
  • Long/Short: Beide Richtungen.
  • Ausstiegskriterien: Der Indikator kehrt zum Durchschnitt zurück.
  • Stops: Ja.
  • Standardwerte:
    • AdxPeriod = 14
    • LookbackPeriod = 20
    • DeviationMultiplier = 1.0m
    • StopLossPercent = 2.0m
    • CandleType = TimeSpan.FromMinutes(5)
  • Filter:
    • Kategorie: Mean Reversion
    • Richtung: Beide
    • Indikatoren: ADX
    • Stops: Ja
    • Komplexität: Mittel
    • Zeitrahmen: Kurzfristig
    • Saisonalität: Nein
    • Neuronale Netze: Nein
    • Divergenz: Nein
    • Risikolevel: Mittel
