ColorJFatl StDev-Strategie

Diese Strategie ist eine Übersetzung des ColorJFatl_StDev-Expertenberaters von MQL5 in die StockSharp API. Sie kombiniert den Jurik Moving Average (JMA) mit Standardabweichungsbändern, um Handelssignale zu generieren.

Strategielogik

  1. Berechnung des JMA auf Schlusskursen.
  2. Berechnung der Standardabweichung über einen konfigurierbaren Zeitraum.
  3. Aufbau von zwei Sätzen dynamischer Bänder mit den Multiplikatoren K1 und K2:
    • upper1 = JMA + K1 * StdDev
    • upper2 = JMA + K2 * StdDev
    • lower1 = JMA - K1 * StdDev
    • lower2 = JMA - K2 * StdDev
  4. Abhängig vom ausgewählten Signalmodus öffnet oder schließt die Strategie Positionen:
    • Point – wird ausgelöst, wenn der Preis die Bänder kreuzt.
    • Direct – verwendet Wendepunkte der JMA-Linie.
    • Without – deaktiviert das entsprechende Signal.

Parameter

Name Beschreibung
CandleTimeFrame Zeitrahmen für Kerzendaten.
JmaLength Periode des Jurik Moving Average.
JmaPhase Phase für die JMA-Berechnung.
StdPeriod Periode für die Standardabweichung.
K1 Erster Abweichungsmultiplikator.
K2 Zweiter Abweichungsmultiplikator.
BuyOpenMode Modus zum Öffnen von Long-Positionen.
SellOpenMode Modus zum Öffnen von Short-Positionen.
BuyCloseMode Modus zum Schließen von Long-Positionen.
SellCloseMode Modus zum Schließen von Short-Positionen.

Verwendung

Die Strategie abonniert Kerzen des angegebenen Zeitrahmens, verarbeitet JMA- und Standardabweichungswerte und übermittelt automatisch Marktorders basierend auf den definierten Modi.

Diese Implementierung konzentriert sich auf Klarheit und kann als Ausgangspunkt für weitere Verbesserungen oder benutzerdefiniertes Risikomanagement dienen.
