La stratégie est un système de trading dynamique qui combine un indicateur aléatoire relativement faible (SRSI) et un indicateur mobile de tendance/diffusion (MACD). Il permet une gestion intelligente du risque en ajustant dynamiquement les points d’arrêt et d’arrêt avec l’indicateur ATR. Le cœur de la stratégie est de générer des signaux de trading par la confirmation croisée de plusieurs indicateurs techniques, tout en gérant les positions en fonction de la volatilité du marché.
Le fonctionnement de la stratégie repose sur les mécanismes centraux suivants:
La stratégie construit un système de négociation robuste en combinant les avantages du SRSI et du MACD. Le mécanisme de gestion dynamique des risques le rend bien adapté, mais nécessite toujours l’optimisation des paramètres par le trader en fonction des conditions réelles du marché. Le fonctionnement réussi de la stratégie nécessite une compréhension approfondie du marché et une gestion rationnelle des positions combinée à la tolérance au risque de l’individu.
