Unsure how to go about it. I'm a long time trader and have always traded reg lots at Global or FXCM or CoesFX in their platforms. I was recently introduced to the metatrader platform and have been finding some achievement massaging (changing/filtering, etc) some of the EAs. However, what I've managed to gather so far is the broker and others use metatrader for miniature lots.

Now, I really don't like miniature lots because of the whole trading against the desk difficulty. I exchange reg lots through the ECN version. My broker has said that the egy can be written for their API and thus I can exchange reg lots . My question is, just how do you go about doing this (writing to an API) and has anyone ever done anything similar to that? Thx.
