Strategie für Kerzenkörper-Formen

Strategie, die basierend darauf handelt, wo eine Kerze innerhalb ihrer Spanne öffnet und schließt. Eröffnet eine Long-Position, wenn die Kerze nahe ihrem Tief öffnet und nahe ihrem Hoch schließt — starker bullischer Druck. Eröffnet eine Short-Position, wenn die Kerze nahe ihrem Hoch öffnet und nahe ihrem Tief schließt — starker bärischer Druck.

Der Ansatz basiert ausschließlich auf Price Action und ist auf jeden liquiden Markt anwendbar.
