Markttrend-Level-Strategie ohne Neuzeichnung

EMA-Crossover-Strategie, die optional Trades mit RSI filtert. Long-Positionen werden eröffnet, wenn der schnelle EMA über den langsamen EMA kreuzt, während Short-Trades beim entgegengesetzten Crossover ausgelöst werden. Wenn ApplyExitFilters aktiviert ist und der RSI-Filter aktiv ist, werden Positionen geschlossen, wenn der RSI die erlaubte Zone verlässt.

Details

  • Einstiegskriterien:
    • Long: Fast EMA kreuzt über Slow EMA und RSI > RsiLongThreshold wenn aktiviert
    • Short: Fast EMA kreuzt unter Slow EMA und RSI < RsiShortThreshold wenn aktiviert
  • Ausstiegskriterien: Entgegengesetzter Crossover oder RSI-Filter versagt wenn ApplyExitFilters wahr ist
  • Typ: Trendfolge
  • Indikatoren: EMA, RSI
  • Zeitrahmen: 5 Minuten (Standard)
