I think "hiding" your true SL and TP in your orders is a good idea, so that the brokers won't get ideas to go stop-hunting on your EA. The problem here is that you could lose connectivity and then your EA will suffer a bigger loss in the case of a downturn in your trade.

Also, can they see our source (.mq4) file? Even if we "hide" our SL's and TP's is there a possibility that they can view our source files since they're in the same folder as the executable (ex4) file? Should we have our source and our executable files in different locations to be even more protected from brokers?

Trying not to be too paranoid, but if your EA is winning a lot, that means someone on the other end is losing, right?

Sigh, you work so hard to put something great together that can beat the market and then you have to worry about beating the dealers too.... this is just like Vegas all over again, the house always wins.
