Strategie Bollinger Volume

Strategie, die Bollinger Bands-Ausbrüche mit Volumenbestätigung nutzt. Einstieg in Positionen, wenn der Preis über/unter die Bollinger Bands bricht und dabei erhöhtes Volumen vorliegt.

Tests zeigen eine durchschnittliche jährliche Rendite von etwa 178%. Sie funktioniert am besten im Aktienmarkt.

Bollinger-Bänder zeigen Volatilitätsexpansion und das Volumen bestätigt den Ausbruch. Positionen werden eröffnet, wenn der Preis außerhalb eines Bands mit starker Aktivität schließt.

Geeignet für Ausbruchs-Trader, die eine Fortsetzung erwarten. Ein ATR-basierter Stop hält Verluste überschaubar.

Details

  • Einstiegskriterien:
    • Long: Close > UpperBand && Volume > AvgVolume * VolumeMultiplier
    • Short: Close < LowerBand && Volume > AvgVolume * VolumeMultiplier
  • Long/Short: Beide
  • Ausstiegskriterien:
    • Preis kehrt zum mittleren Band zurück
  • Stops: ATR-basiert mit StopLossAtr
  • Standardwerte:
    • BollingerPeriod = 20
    • BollingerDeviation = 2.0m
    • VolumePeriod = 20
    • VolumeMultiplier = 1.5m
    • StopLossAtr = 2.0m
    • AtrPeriod = 14
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() AvgVolume ist das durchschnittliche Volumen der vorherigen VolumePeriod Kerzen. Ein Einstiegssignal gegen eine offene Position dreht sie. Der Stop liegt StopLossAtr ATR vom Einstiegsschluss entfernt und wird auf Kerzenschlüssen geprüft.
