While EA was still running live doing auto-trading I modified some code and compilied it but didn't removed and reattach EA on MT4 terminal.So in that codition will EA be running will be modified too or it will use the old compilation code.
Look at the experts log tab. You will see if EA is reinitialized when you compiled it (it will have log entries for deinit and after that for init).
If it is reinitialized, then it is using new code.
