Hull Candles Strategie

Hull Candles ist eine einfache Trendfolge-Strategie, die einen Hull Moving Average des Durchschnittspreises (OHLC4) verwendet. Wenn das HMA steigt und der Schlusskurs über seiner SMA liegt, werden Long-Positionen eröffnet; wenn das HMA fällt und der Schlusskurs unter seiner SMA liegt, werden Short-Positionen eröffnet.

Details

  • Daten: Preiskerzen.
  • Einstiegskriterien:
    • Long: HMA steigt und Schlusskurs > SMA.
    • Short: HMA fällt und Schlusskurs < SMA.
  • Ausstiegskriterien: Umgekehrtes Signal.
  • Stops: Keine.
  • Standardwerte:
    • BodyLength = 10
    • SmaLength = 1
  • Filter:
    • Kategorie: Trendfolge
    • Richtung: Long/Short
    • Indikatoren: HMA, SMA
    • Komplexität: Niedrig
    • Risikolevel: Hoch
