Convert MT4 EA to MT5 (please check description and attachments!)

//---- Read values from the signal buffer
int start()
{
// Read signal for this bar
double value = iCustom(Symbol(), Period(), "PZ_DayTrading_LICENSE", 4, 1);
// Do something
if(value == OP_BUY) { /* Your code for bullish signal */ }
if(value == OP_SELL){ /* Your code for bearish signal */ }
if(value == EMPTY_VALUE) { /* Your code if no signal */}
// Exit
return(0);
}

-> Providing source code after completion

If there is some part of the EA function you don't understand or is not clear, the original project spec is attached, so you can reference that to make sense of the code's function. PLEASE UNDERSTAND that is NOT the job spec. That is the ORIGINAL project spec so you can understand HOW THE EA WORKS IF YOU NEED HELP UNDERSTANDING. Some people do not read this description properly and then send me abuse.

Source code will be provided to applicants to review before proceeding because I just don't want the code out there for people to randomly see.
