La stratégie est basée sur le célèbre système de négociation de coquillages, développé selon des règles aussi primitives que possible. Il s’agit d’un système de suivi des tendances, qui forme des signaux d’entrée et de sortie à travers des lignes doubles.
Cette stratégie présente les avantages suivants:
Cette stratégie comporte aussi des risques:
Le risque peut être réduit par:
Cette stratégie peut être optimisée dans les domaines suivants:
Cette stratégie a un certain avantage de rétroaction en suivant les tendances. Cependant, l’efficacité du marché réel doit encore être testée. Il est nécessaire d’optimiser davantage la stabilité des paramètres, d’améliorer le module de gestion des stop-loss et des positions pour que la stratégie soit plus adaptée au marché réel.
