Cette stratégie est un système de suivi de tendance basé sur l’ATR (Average True Range) qui suit de manière dynamique les arrêts de perte. Il combine la ligne moyenne EMA comme filtre de tendance et contrôle la génération de signaux en ajustant les paramètres de sensibilité et la période ATR. Le système prend en charge non seulement les transactions en plus, mais aussi en détail, et dispose d’un mécanisme de gestion des bénéfices parfait.
Il s’agit d’un système de suivi de tendance structuré et logiquement clair. Le suivi dynamique d’ATR et le filtrage des tendances EMA sont combinés pour mieux contrôler les risques tout en maîtrisant les tendances. La conception du mécanisme de profit par tranches reflète également une pensée de trading mature.
