You can copy and host your Stop Loss and Take Profit on the Slave account.
By enabling the Copy Stop Loss and Take Profit feature, the Stop Loss and Take Profit on the Master will be copied and hosted directly on the Slave at the order creation. If this is disabled, as soon as the SL/TP is triggered on the Master, it will send a Market order to the Slave to close the position.
** A paid plan is required to enable this function**
