Il s’agit d’une stratégie de négociation quantitative basée sur le support et la résistance. La stratégie consiste à identifier les points de soutien et de résistance critiques et à effectuer la transaction à la confirmation de la résistance après la rupture.
Les stratégies comprennent principalement les éléments suivants:
La stratégie est construite à partir de la théorie classique de la résistance au support et de la logique de retracement de la rupture, avec une bonne base théorique. Des résultats commerciaux stables peuvent être obtenus grâce à l’optimisation des paramètres et au contrôle des risques. La structure du code de la stratégie est claire, facile à comprendre et à étendre, avec une forte valeur pratique.
