Tradestation to FXCM API

I just want to put the code in so that when I do a buy or sell or close position in tradestation it will do it automatically in FXCM tradestation II platform as well so I dont need to go back and forth between the two platforms. Prices don't matter I just want it to be doing the same trades simultaneously as I do it on tradestation. I will need instruction how to set it up so that the FXCM API receives message from tradestation that it must buy or sell or close the position.
