Dies ist eine Strategie, die MACD-, RSI- und Stochastische Indikatoren verwendet, um die Kursdynamikrichtung zu bestimmen, und macht lange oder kurze Einträge an Momentum-Breakout-Punkten.
Die Strategie verwendet MACD, RSI und Stochastic Indikatoren, um die Trendrichtung der Preise zu bestimmen. Wenn die MACD
Wenn nach dem Eintreten einer Position einer der drei Indikatoren ein Umkehrsignal erzeugt, bedeutet dies, dass der Trend umgekehrt ist und die aktuelle Position verlassen sollte.
Verbesserungsrichtlinien:
Insgesamt handelt es sich um eine typische Trendfollowing-Strategie. Sie verwendet mehrere Indikatoren, um den Trend für Eintritte zu bestimmen, und Umkehrsignale, um Trendende für Ausgänge zu beurteilen, und kombiniert sowohl Trendfollowing- als auch Umkehrmechanismen.
Zusammenfassend ist die Logik dieser Strategie klar, und die verwendeten Indikatoren sind auch typisch. Es funktioniert gut in einigen Details der Optimierung und Risikokontrolle und kann eine real-wertstaugliche Quant-Strategie sein. Aber es gibt immer noch einige Lücken von Perfektion, die weitere Tests und Optimierungen erfordern, um das Rendite-/Drawdown-Verhältnis der Strategie auf ein professionelles Niveau zu bringen. Mit kontinuierlicher Optimierung und Aktualisierungen kann diese Strategie langfristig nachverfolgt werden.
