Yeah. Most EA's dont handle slippage or requote handling properly. This is where they fail in fast moving markets. You also need ot build in currency spread handling.
Since a lot of programmer join in this thread, i want to ask if there is someone who already trade live with Expert Advisor? Could you share the experiences with us?
I have tested guardian and it works, but I cannot say if it is unbreakable. If you are looking to secure your source code, I think there is no way to do it. But you can make reading the source code such a pain in the ass, so no one will try to understand your logic (for example use recursion instead of cycles, use ascii codes for strings, use stupid names for your variables like '___' and '___________' (yes it compiles correctly) and much more.)
yes there is no 100% way, everything in life is matter of efford, not even microsoft can protect itself from pirates. Guardian is not unbreakable, neither the way you suggest (btw this exists and called mt4 enigma or so), neither exporting functions to .dll helps. Guardian is an approach to protect source codes. What we have done is that we dont encrypt every .ea with same algo nor password. We do encrypt every EA different way.
