We have developed STP add-on which allows catch modification or closure request on the master terminal and copy it to slave. As soon as you or your Forex robot will send modification request or closure request, copier will copy this command to slave immediately without waiting when the order will be modified or closed on the master terminal.
If your strategy has closure condition by Take Profit or Stop Loss only, you can use this add-on for orders opening too. But if your strategy has other closure conditions, we do not recommend to use STP add-on for orders opening. Because this can lead to abnormal situations when the order was for some reason not accepted by the server on the master account, but has been copied to slave account.
