Aide LotSize automatique

[Karasoshi]

Bonjour, je suis débutant en programmation et je code un EA fonctionnant autour du point pivot. Ma problématique est que je n'arrive pas à faire un code qui permette de calculer automatiquement la taille du lot en fonction de la distance du SL et du risque par trade. Je veux un risque réglable de 2 pourcent et surtout arriver à calculer le lot avec le sl qui est la distance entre le point d'ouverture du trade et le point pivot.

Voici mon code actuel:
