http://docs.mql4.com/ru/index
Also beginners will help MT4 (called the F1 key in the terminal) and reference editor MetaQuotes Language (press F4 in the terminal MT4, then F1).

You can disassemble the finished program - which commands are used, how they work, etc. And you can begin by writing a simple trading algorithm to further the finished "skeleton" to impose new commands or change ready. Ie from the simple - to more complex.

Also, when you create a trading robot is definitely useful tips and tricks of the traders (programmers) who already have some experience in this matter. You can find a lot of useful forums for traders who use language MQL4 (www.mql4.com/ru) or MQL5 (www.mql5.com/ru). Here you can get an answer to almost any question related to the writing of trading advisers and not only.

Advisor MQL4 - advice from experienced programmers

* As soon as the opportunity to do the testing of the finished piece of code or function - do it immediately. Later, when the program will grow to large sizes, will be harder to make sure that it works.

* Pieces of code that are repeated often better to arrange the individual functions.

* No need to strive to write optimal code. To begin, create something that will work properly - even if the code is ugly or bulky. Subsequently, the corrected code optimization.

* Do not be shy to use their own algorithms, despite having prepared or seemingly more perfect you. Priority - the correctness of the program, which is impossible without an understanding of how to operate a particular algorithm.
