I'm having Account in just two dealer terminals.A supervisor Account In one dealer platform customer Account In a different Platform.i.e if I'm trading in the one account I would like to create an EA that opens an order when an order is opened to your customer in another platform.

I.e I'm having a Account 'abc' in 123 dealer platform
an account 'def' in 456 dealer platform.

If I start a commerce for abc,exactly the identical trade should be opened for def also,if I shut commerce for abc it should shut for def also. I would like to create an EA for it.
