The reverse position will be sent from the master to the slave as soon as the order is triggered on the master. With a market order, we cannot guarantee the execution price. However, if you use a stop or limit order that is copied on the slave, the slave will wait for the price to be triggered on the slave, but the stop/limit price is the same as the master's. The slave trade will be closed as soon as the master trade is closed, either at a market price or with an SL or TP.
