some questions for MQL4
vx0532:
Read the Book, it's in there: https://book.mql4.com/basics/programms
I have two questions about MQL4 as below:
1. what is the difference between "Expert Advisors" and "Scripts" in MQL4. I mean that I write a unit of program code--"x",when I put "x" in "start()" of Expert Advisor, the code work well; but when I put it in "start()" of Scripts, it never works, and MT4 complain that "can't call function". so why it is?
2. How shall I review the primary code for MQL4's functions, such as OrderClose(), OrderSend(), and so on.
