A cTrader OCO (One Cancels the Other) Order is a powerful tool for Forex traders allowing them to set two orders in one entry, with either order executing and cancelling the other when triggered. The two orders that are placed in the OCO order must be of opposing type, meaning a buy limit and a sell limit, or a buy stop and a sell stop. This setup is used to maximize potential return when either of the two orders gets triggered. It also helps to reduce risk by allowing traders to set their potential profit and loss targets at once. It requires a moderate level of sophistication to utilize the OCO order strategy correctly.
