Adaptive SMI-Ergodic-Strategie

Die adaptive SMI-Ergodic-Strategie verwendet den True Strength Index (TSI)-Oszillator mit einer EMA-Signallinie, um Umkehrungen aus Überkauf- oder Überverkauft-Extremen zu erkennen. Eine Long-Position wird eröffnet, wenn TSI den Überverkauft-Schwellenwert nach oben kreuzt und dabei über seiner Signallinie bleibt. Eine Short-Position wird eröffnet, wenn TSI den Überkauf-Schwellenwert nach unten kreuzt und unter der Signallinie liegt.

Details

  • Einstiegskriterien:
    • TSI kreuzt über Überverkauft und TSI > Signal (Long).
    • TSI kreuzt unter Überkauft und TSI < Signal (Short).
  • Long/Short: Beide.
  • Ausstiegskriterien:
    • Ein umgekehrtes Signal löst den entgegengesetzten Trade aus.
  • Stops: Keine.
  • Standardwerte:
    • LongLength = 12
    • ShortLength = 5
    • SignalLength = 5
    • OversoldThreshold = -0.4
    • OverboughtThreshold = 0.4
  • Filter:
    • Kategorie: Momentum-Oszillator
    • Richtung: Long/Short
    • Indikatoren: True Strength Index, EMA
    • Stops: Nein
    • Komplexität: Niedrig
    • Zeitrahmen: Beliebig
    • Saisonalität: Nein
    • Neuronale Netze: Nein
    • Divergenz: Nein
    • Risikolevel: Niedrig
