Cette stratégie est basée sur l'indicateur Williams %R et optimise les performances de trading en ajustant dynamiquement les niveaux de prise de profit et de stop-loss. Les signaux d'achat sont générés lorsque le Williams %R franchit la zone de survente (-80), et les signaux de vente sont générés lorsqu'il franchit la zone de surachat (-20). Une moyenne mobile exponentielle (EMA) est utilisée pour lisser les valeurs de Williams %R et réduire le bruit. La stratégie offre des paramètres flexibles, y compris les périodes d'indicateur, les niveaux de prise de profit/stop-loss (TP/SL), les heures de trading et les choix de direction du commerce, pour s'adapter aux différentes conditions du marché et aux préférences du trader.
La stratégie d'ajustement dynamique TP/SL de Williams %R capte les conditions de prix de surachat et de survente de manière simple et efficace tout en fournissant des paramètres flexibles pour s'adapter à différents environnements de marché et styles de trading.
