Hi pizd0s, thanks for the response -- that is actually helpful, I will look for their terms of service -- also in the meantime, when googling the term A Book and B Book as someone suggested above -- I found a few pages in the Baby Pips pipsology school that describe how it is common now for books to take a hybrid approach to execution/hedging -- and that makes sense -- so I guess the answer to my bigger question is that all is good with these regulated U.S. books like Oanda and Forex.com (I have been using Forex.com) even though they are not necessarily putting all of my trades through to an underlying instrument -- they are managing it and it is not the case that anything I earn comes directly out of their bottom line -- so I am guessing they will not kick me out if I start making more substantial money -- thanks again!
