Decompiling is a lot harder than it used to be, so they are already protected to some extent. (not 100% as MT can decode them )

For more protection:

1. Use signals - (requires infrastructure)
2. Lock code to account ID - need a process for users to change account and allow for Demo / backtesting.

write account check code in EA? or write image with account ID ?

hardcode the account number in the mq4 then compile unique ex4 for each customer.
I suspect you wont be able to patch the ex4 after compiling because (I'm guessing) the protection on ex4 involves some kind of signing/checksum.
