Les avantages de cette stratégie:
Il y a aussi des risques:
Les risques peuvent être réduits par:
La stratégie peut être améliorée de la manière suivante:
La stratégie profite en suivant la tendance et a de bons résultats de backtest. Mais les performances réelles doivent être validées. Une optimisation supplémentaire de la robustesse des paramètres, du stop loss et de la taille des positions est nécessaire avant de l'appliquer dans le trading en direct. Dans l'ensemble, elle a une logique solide et beaucoup de potentiel d'amélioration.
