It sounds like you are describing the MT4 bridge, but your description of the problem is extremely unclear.

Make sure to install the MT4 bridge 100% correctly. Follow the steps down to the letter.

By the way, the MT4 bridge is free to use in demo mode, but you need to get the Zorro S license to trade live.
