Bonjour et bonsoir a vous tous, j'ai codé une stratégie parlant de la cassure des high et Low lors de la session de Londres, qui constitue a prendre une position acheteur lorsque le prix casse le high de la session asiatique et une position vendeur lorsque le prix casse le Low de la session asiatique.
Voici le code source, comme je suis débutant, je vous laisse me corriger en commentaire, et j'aimerais que vous repondiez au sondage suivant :
1. la stratégie London Breakout est-il rentable ou non ?
2. le code écrit est-il bon ou mauvais ?
J'attend vos réponses avec impatients.
