- Je ne sais pas.

Ce script est inspiré de Vitali Apirine (Stocks & Commodities V.36:5: Adaptive Moving Averages) et une correction de Dynamic Volume Adaptive Moving Average (MZ DVAMA). L'adaptation de la pente permet aux moyennes mobiles adaptatives de détecter mieux l'état de la tendance, ce qui facilite la prise de décisions basées sur des dynamiques de prix, des consolidations ou des ruptures de marché. La courbe des moyennes mobiles adaptatives ne change pas sa longueur en fonction de la pente, mais elle utilise une couleur adaptative à la pente pour détecter la force de la tendance.

Détection des tendances Couleur verte: Une forte tendance haussière avec une bonne dynamique des prix. Couleur rouge: Une forte tendance à la baisse. Couleur jaune: Il est préférable d'éviter de prendre de nouvelles positions et si le commerce fonctionne, il est bon de continuer.

Par défaut La longueur de l'AMA est de 200 (meilleur pour les délais supérieurs à 1H) La longueur mineure est de 6 La longueur majeure est de 14 La période de pente est fixée à 34 avec 25 de la plage initiale. Alertes Les alertes d'achat/vente suivront lorsque la pente est en dehors de la zone de consolidation/décalage.
