Strategie Tweezer Top

Der Tweezer Top spiegelt die Bodenversion, erscheint aber nach einem Aufschwung. Zwei Kerzen teilen nahezu dasselbe Hoch und zeigen, dass Käufer nicht über ein bestimmtes Niveau hinaus drücken konnten.

Tests zeigen eine durchschnittliche jährliche Rendite von etwa 187%. Die Strategie funktioniert am besten am Aktienmarkt.

Die Strategie eröffnet eine Short-Position, sobald die zweite Kerze die Decke bestätigt, und erwartet einen Rückzug, wenn der bullische Schwung ins Stocken gerät.

Ein enger Stop oberhalb der Doppelhochs hält das Risiko in Schach, und der Trade wird beendet, wenn der Preis wieder über diesen Widerstand klettert.
