Je vous en prie.Mon frère pose une question, la logique de cette stratégie est de détecter si le prix a franchi le seuil et d'envoyer plus de billets, c'est-à-dire d'attendre que la barre soit terminée avant d'entrer ou d'entrer immédiatement si le prix actuel est franchi toutes les 0,5 secondes dans la détection?
L'inventeur de la quantification - un petit rêveOui, la stratégie est un mécanisme onTick qui déclenche une commande dès que le prix est déclenché, bien sûr, il peut également être conçu comme un mécanisme onBar.
