Cette stratégie met en œuvre un module de limite de temps basé sur la stratégie de moyenne mobile double originale pour contrôler l'heure de début de la stratégie.
La stratégie génère des signaux de trading en utilisant des MA rapides et lents. Le MA rapide a une période de 14 jours et le MA lent a une période de 21 jours. Un signal d'achat est généré lorsque le MA rapide franchit le niveau du MA lent. Un signal de vente est généré lorsque le MA rapide franchit le niveau du MA lent.
La stratégie intègre également une option d'inversion des échanges pour inverser la direction initiale des échanges.
Le module limite de temps compare l'heure actuelle à l'heure de démarrage configurée en utilisant des horodatages, renvoyant true ou false pour contrôler si la stratégie démarre ou non. L'année de démarrage, le mois, le jour, l'heure et la minute doivent être définis. La stratégie ne démarrera que lorsque l'heure actuelle dépasse l'heure de démarrage configurée.
L'optimisation des périodes de MA peut réduire la fréquence des transactions. L'heure de début doit également être définie de manière rationnelle pour éviter de manquer des opportunités. Enfin, choisissez soigneusement d'inverser les signaux en fonction des conditions du marché.
Cette stratégie génère des signaux de trading en utilisant des MAs doubles et contrôle le temps de fonctionnement avec le module de limite de temps, capturant efficacement les tendances tout en évitant les conditions défavorables du marché.
