La version Python de la stratégie de couverture intertemporelle Bollinger sur les contrats à terme sur matières premières (uniquement à des fins d'étude)

La stratégie d'arbitrage intertemporel précédemment écrite nécessite l'entrée manuelle de l'écart de couverture pour l'ouverture et la fermeture des positions.

Réglage des paramètres de stratégie:

Le cadre global de la stratégie est essentiellement le même que celui de la stratégie deVersion Python de la stratégie de couverture intertemporelle des contrats à terme sur matières premièresLorsque la stratégie est en cours d'exécution, les données de la ligne K des deux contrats sont obtenues, puis la différence de prix est calculée pour calculer l'écart.TA.BOLLLorsque l'écart dépasse le rail supérieur de la bande de Bollinger, il sera couvert, et lorsqu'il touche le rail inférieur, il sera opposé à l'opération.
