Cette stratégie est un système de trading basé sur les bandes de Bollinger et l'analyse des modèles de bougies, conçu pour capturer les inversions de marché en analysant la volatilité des prix et les caractéristiques des bougies sur la période quotidienne.
La stratégie utilise des bandes de Bollinger à 20 périodes comme indicateur technique principal avec un multiplicateur d'écart type de 2,0. En calculant le rapport entre les ombres et les corps des bougies, le système génère des signaux de trading lorsque ce rapport dépasse un seuil défini (défault 1.0) et que le prix touche les limites des bandes de Bollinger.
Il s'agit d'un système de négociation complet combinant les bandes de Bollinger et l'analyse des bougies pour saisir les opportunités d'inversion du marché. Les atouts de la stratégie résident dans son cadre analytique complet et son système de gestion des risques robuste, tout en accordant une attention particulière aux conditions du marché et aux impacts de la sélection des paramètres.
