Cette stratégie combine des niveaux de support/résistance dynamiques avec les bandes de Bollinger et l'EMA21 pour une approche de négociation croisée multi-indicateurs. Elle identifie les écarts des niveaux de prix clés tout en utilisant des croisements d'indicateurs techniques pour prendre des décisions de négociation. La stratégie identifie non seulement dynamiquement les niveaux de support/résistance importants dans la structure du marché, mais confirme également les signaux de négociation grâce à la coordination des bandes de Bollinger et des moyennes mobiles.
La stratégie repose sur plusieurs éléments essentiels: 1. Calcul dynamique de support/résistance: utilise la méthode des points pivots pour calculer dynamiquement les niveaux de support/résistance du marché, en filtrant les zones de prix efficaces à travers la largeur du canal et les exigences de résistance minimale. 2. Bandes de Bollinger: utilise des bandes de Bollinger à 20 périodes et 2 écarts types pour définir les plages de volatilité des prix. 3. EMA21: sert de ligne de référence pour le jugement des tendances à moyen terme. Génération de signaux commerciaux: exécute les transactions lorsque le prix franchit les niveaux de support/résistance tout en déclenchant simultanément des signaux de bande de Bollinger.
Cette stratégie construit un système de trading relativement complet en combinant le support/résistance dynamique, les bandes de Bollinger et l'EMA21. Ses atouts résident dans la confirmation de signaux multidimensionnels et l'adaptation dynamique du marché, tout en faisant face à des défis en matière d'optimisation des paramètres et de faux risques de rupture.
