Strategie für gerichtete Bewegungskerzen

Die Strategie überwacht den Relative Strength Index (RSI) auf Kerzenschlusskursen. Wenn der RSI die neutrale Zone verlässt und benutzerdefinierte Niveaus kreuzt, eröffnet die Strategie Positionen in Richtung des Momentums und schließt jedes entgegengesetzte Exposure.

Details

  • Indikator: Relative Strength Index mit einstellbarem RsiPeriod.
  • HighLevel: RSI-Wert, der bullisches Momentum anzeigt.
  • MiddleLevel: Neutralschwelle als Referenz.
  • LowLevel: RSI-Wert, der bearisches Momentum anzeigt.
  • Einstieg:
    • Long wenn RSI über HighLevel steigt, nachdem er darunter war.
    • Short wenn RSI unter LowLevel fällt, nachdem er darüber war.
  • Ausstieg: Das entgegengesetzte Signal schließt die bestehende Position, bevor eine neue eröffnet wird.
  • Long/Short: Beide Richtungen.
  • Stops: Standardmäßig nicht verwendet.
  • Standardwerte:
    • RsiPeriod = 14
    • HighLevel = 70
    • MiddleLevel = 50
    • LowLevel = 30
    • CandleType = 5-Minuten-Zeitrahmen
