4H Bollinger Ausbruch-Strategie

Die 4H Bollinger Ausbruch-Strategie handelt Bollinger-Band-Ausbrüche auf dem Vier-Stunden-Chart. Long-Positionen werden eröffnet, wenn der Preis über das untere Band kreuzt und Volumen sowie Trend bestätigen. Short-Positionen werden eingegangen, wenn der Preis unter das obere Band kreuzt und der RSI unter einem Schwellenwert liegt.

Details

  • Einstiegskriterien:
    • Long: Schlusskurs kreuzt über das untere Band, Volumen über seinem SMA und Preis über dem Trend-SMA.
    • Short: Schlusskurs kreuzt unter das obere Band, Volumen über seinem SMA, Preis unter dem Trend-SMA, RSI < 85.
  • Long/Short: Beide Seiten.
  • Ausstiegskriterien:
    • Long: Schlusskurs kreuzt über das obere Band.
    • Short: Schlusskurs kreuzt unter das untere Band.
  • Stops: Keine.
  • Standardwerte:
    • BollingerLength = 20
    • BollingerMultiplier = 1.8
    • VolumeLength = 20
    • TrendLength = 80
    • RsiLength = 14
    • UseLongSignals = True
    • UseShortSignals = True
  • Filter:
    • Kategorie: Trend-Ausbruch
    • Richtung: Beide
    • Indikatoren: Bollinger Bands, Volumen-SMA, Trend-SMA, RSI
    • Stops: Keine
    • Komplexität: Moderat
    • Zeitrahmen: 4H
    • Saisonalität: Nein
    • Neuronale Netze: Nein
    • Divergenz: Nein
    • Risikolevel: Mittel
