Looking at your posting history (https://opserver.de/ubb7/ubbthreads.php?ubb=userposts&id=20749), I see that you post all kinds of API requests to small/local/unknown brokers.

Why not a) write your own connector, b) pay the Zorro devs to do so or c) switch to a broker which is already supported? With so many MT4/5 brokers, it can't be that hard to find a good one.

Thanks Grant.
Order like : the stop limit order , OCO, brackets , If I connect the MT5 to zorro, are this type of orders correctly placed on MT5 by Zorro?

Not OCO, but Zorro supports the GTC type as a possible workaround. It also depends on the broker if those order types are supported.

I would suggest to read the manual and try things with a demo account.
