Set Stop Loss on Limit Price

Définit le Stop Loss à un niveau spécifié si le prix d’ouverture de l’ordre est supérieur (pour une position longue) ou inférieur (pour une position courte) à une limite de prix.

Si vous avez plusieurs positions ouvertes, cela évitera de placer un stop loss sur les positions perdantes. Ce qui pourrait clôturer immédiatement la position
