La stratégie est basée sur l’idée de briser les supports et les résistances clés, en identifiant les lignes de tendance haussière et baissière clés dans le graphique des prix, et de négocier lorsque les prix franchissent les lignes de tendance. La stratégie est simple et fiable et s’applique dans un environnement de marché où la tendance est claire.
La stratégie identifie les points critiques de hausse et de baisse des prix en calculant les hauts et les bas des lignes pivotantes à gauche et à droite, afin d’obtenir des lignes de support et de pression.
utiliserpivothigh()etpivotlow()La fonction détecte les hauts et les bas critiques.
Les équations de la ligne de soutien et de la ligne de pression sont tracées en fonction des hauts et des bas.
Lorsque le prix dépasse la ligne de pression, faites plus; lorsque le prix dépasse la ligne de support, faites moins.
Choisissez de faire plus ou moins selon la direction de la tendance.
Il est possible de choisir d’effectuer un virage direct de la position au moment de la rupture.
Il est possible d’utiliser le stop-loss, le stop-stop et le stop-tail.
Il est possible de choisir entre un arrêt de point de swing, un arrêt ATR et un arrêt fixe.
Cette stratégie est simple et pratique, car elle permet de déjouer les transactions en utilisant des indices de tendance simples, tout en permettant le suivi et le renversement des tendances.
Le risque peut être réduit par l’optimisation des stratégies de stop loss, l’évaluation de la qualité des signaux de rupture et l’évaluation du temps de retour.
La stratégie est simple et pratique dans l’ensemble, elle permet de capturer les tendances des prix par une simple rupture de tendance, le risque est contrôlable. La stratégie peut être optimisée de plusieurs façons, elle s’applique à plus de situations de marché, et est une stratégie de suivi de tendance très pratique dans l’ensemble.
