Die Bullish Engulfing-Kauf- und Verkaufsstrategie ist eine quantitative Handelsstrategie, die auf K-Linienformationen basiert. Die Strategie nutzt die Gelegenheit, einen Kurswechsel zu erfassen, indem sie die K-Linienformationen von Bullish Engulfing identifiziert und Gewinne erzielt.
Die wichtigsten Vorteile dieser Strategie sind:
Die Strategie basiert auf dem Trend von Bullish Engulfing, bei dem die K-Linie von Yang Yang verschluckt wird, um eine Kursumkehr zu ermitteln.
Wenn eine K-Linie mit einem kleineren Wurf entsteht, der der nachfolgenden K-Linie folgt und die K-Linie vollständig verschlingt, und der Schlusskurs über dem Höchstwert der vorherigen K-Linie liegt, wenn die Aktie im Abwärtstrend ist, entsteht eine Bullish Engulfing-Grossal, die darauf hindeutet, dass eine Kursumkehr bevorsteht, und die Aktienpreise steigen.
Die Strategie eröffnet zusätzliche Positionen, wenn die Bullish Engulfing-Form erkannt wird, und setzt die Stop-Loss-Exit-Strategie mit einem Ziel von 1% Gewinn, 1% Verlust und Lockerung des Gewinns.
Diese Strategie hat folgende Vorteile:
Die Strategie birgt auch einige Risiken:
