Strategie Volatility Adjusted Moving Average

Diese Technik modifiziert ein gleitendes Durchschnittsband um ein ATR-Vielfaches. Wenn der Preis über das angepasste Band hinausgeht, deutet das auf einen beschleunigten Trend hin.

Tests zeigen eine durchschnittliche jährliche Rendite von etwa 160%. Es funktioniert am besten auf dem Forex-Markt.

Long-Trades werden oberhalb des oberen Bandes eröffnet, Shorts unterhalb des unteren Bandes. Ein Rückkreuzen durch den Basis-gleitenden-Durchschnitt schließt die Position.

Da sich die Bänder mit der Volatilität ausdehnen, passen sich die Stops den Marktbedingungen an.
