Coding help needed to reverse BUY/SELL execution

Beginner like me do not produce good EA, even that it through Expert Adviser Builder ( http://sufx.core.t3-ism.net/ExpertAdvisorBuilder/ )

I would like to reverse the BUY/SELL execution but not by modifing the original code generated, buy just adding more code to achieve this objective. The code should just intercept the execution signal produce by the original code reverse this signal before passing it over to Meta Trader. That may turn a bad EA to a good one.

Any one that can help ?

that won't turn the EA into a good one.
