Altarius RSI Stochastic-Strategie

Überblick

Die Altarius RSI Stochastic-Strategie ist eine direkte Konvertierung des MetaTrader 5 Expert Advisors "Altarius RSI Stohastic" in StockSharp's High-Level-API. Das System synchronisiert zwei Stochastic-Oszillatoren mit einem schnellen 3-Perioden-RSI, um kurzlebige Umkehrungen zu erfassen, die auftreten, wenn der Momentum komprimiert und dann wieder expandiert. Die StockSharp-Implementierung bewahrt die ursprüngliche Ein- und Ausstiegslogik und fügt moderne Annehmlichkeiten wie Strategieparameter, automatisches Risikomanagement und adaptives Positionssizing hinzu.

Funktionsweise

  • Primärer Stochastic (15/8/8): Dient als Trendfilter. Long-Positionen erfordern, dass die %K-Linie unter 50 liegt und die %D-Linie von unten kreuzt, was aufwärts gerichteten Momentum in einer neutralen bis überverkauften Zone signalisiert. Short-Positionen erfordern die Spiegelbedingung oberhalb von 55.
  • Sekundärer Stochastic (10/3/3): Misst, wie stark %K von %D abweicht. Ein minimaler absoluter Abstand von 5 Punkten ist erforderlich, um den Momentum vor dem Einstieg zu validieren.
  • RSI (Periode 3): Kontrolliert die Ausstiege. Long-Positionen werden geschlossen, wenn der RSI 60 überschreitet und das primäre %D von über 70 nach unten dreht. Short-Positionen werden beendet, wenn der RSI unter 40 fällt und das primäre %D von unter 30 nach oben dreht.
  • Drawdown-Schutz: Wenn der schwebende PnL unter das konfigurierbare Risikomultiplikator des Kontokapitals fällt, liquidiert die Strategie sofort die offene Position – ähnlich wie der Notfall-Stop im Originalcode.
  • Adaptives Sizing: Das anfängliche Volumen wird aus dem Portfoliokapital multipliziert mit dem MaximumRisk-Faktor und dividiert durch 1000 abgeleitet, entsprechend dem MT5-Ansatz. Aufeinanderfolgende Verlustgeschäfte reduzieren die Positionsgröße gemäß dem DecreaseFactor, unter Beachtung eines Mindesthandelsvolumens.

Handelsregeln

  1. Einstiegskriterien
    • Long: Primäres %K > primäres %D, primäres %K < PrimaryBuyLimit, und |sekundäres %K − sekundäres %D| > DifferenceThreshold, während die Strategie flat ist.
    • Short: Primäres %K < primäres %D, primäres %K > PrimarySellLimit, und |sekundäres %K − sekundäres %D| > DifferenceThreshold, während die Strategie flat ist.
  2. Ausstiegskriterien
    • Long-Ausstieg: RSI > LongExitRsi, primäres %D > PrimaryExitUpper, und der aktuelle %D-Wert ist niedriger als der der vorherigen Kerze.
    • Short-Ausstieg: RSI < ShortExitRsi, primäres %D < PrimaryExitLower, und der aktuelle %D-Wert ist höher als der der vorherigen Kerze.
    • Risikoausstieg: Wenn der schwebende Verlust MaximumRisk × Portfolio.CurrentValue überschreitet.

Risikomanagement

  • Die Strategie ruft automatisch StartProtection() auf, um StockSharp's integrierte Positionsschutzdienste zu aktivieren.
  • Die Positionsgröße wird reduziert, wenn _lossStreak mehr als ein aufeinanderfolgendes Verlustgeschäft überschreitet, und ahmt die MT5-DecreaseFactor-Logik nach.
  • MinimumVolume verhindert, dass die Positionsgröße unter die Mindesttickanforderungen der Börse fällt.

Hinweise

  • Die Strategie setzt ein hedging-fähiges Portfolio voraus, genau wie der ursprüngliche EA.
  • Passen Sie den CandleType-Parameter an den Zeitrahmen an, den Sie in MetaTrader verwendet hätten (M1, M5 usw.).
  • Kombinieren Sie dieses Modul mit StockSharp Designer oder dem Backtester-Projekt in diesem Repository, um die Performance mit Ihren eigenen Daten zu validieren.
