Hey, what you need is the manual that comes with MetaTrader editor. Press F1 for it. If you know how to code C, it'd be just easy to code in mql4. Syntax is pretty similiar to C but much easier to grasp.

The effective way to learning mql4 is to look at somebody's code, particularly, the EAs that you like, read them line by line, try to make sense what each line do. After that, you should just start coding right away. You'll learn when you stumble into problems; that's for sure. That's how I learn mql4.
