Thanks Patrick

thats a very interesting idea to use the FTP.

however I do want to be able to interact with MT - to send the tick and candle info to the .net app and this app communicate back to MT on when to trade.

I found this that I thought may help - Simplified Wrapper and Interface Generator
However I am a rather entry level programmer, and dont fully appreciate what is involved in having a c++ wrapper middle layer.

I would be interested to hear your opinion, if you think this could be a useful tool to use to help bridge between the c++ and .net?
