ProTrader Desktop is equipped with a powerful language allowing you to write trading system rules, define your own indicators, macros and autobrokers. This chapter explains the language structure, supported data types, statements and gives you reference of built-in analysis and trading functions .

In comparison with other language, PTL has at least two great advantages:

1) It is very simple. The traders can create scripts fastly and comfortly.
2) It look like very popular language family named MetaQuotes Language (MQL). So, MQL-traders can learn it easy.

If you want to get comfort access to all build-in functions or you want to create really good scripts, we recommend you to try PTL. The PTL scripts are stable and error-safe because compiler forbids to use some danger operations with data types. When some error occurred in your code during testing PTL engine will generate exception message and you can made fast fix.

Note: PTL scripts works faster then MQL4 and EL. We keep adding new functions into PTL! From PTL you can get access to all build-in functions form any supported language.

We wish you good luck with creating you own scripts...
