MetaQuotes Language 5 (MQL5) is a built-in language for programming trading strategies. This language is developed by MetaQuotes Software Corp and allows to create your own Expert Advisors that make trading management automated and are perfectly suitable for implementing your own trading strategies. Besides, using MQL5 you can create your own technical indicators (custom indicators), scripts and libraries.

MQL5 contains a large number of functions necessary for analyzing current and previously received quotes and has built-in basic indicators and functions for managing trade positions and controlling them. The MetaEditor 5 (text editor) that highlights different constructions of MQL5 language is used for writing the program code. It helps users to orientate themselves in the expert system text quite easily.

MQL5 is the evolution of its predecessor - the MQL4 programming language, in which numerous indicators, scripts, and Expert Advisors were written. Despite the fact that the new programming language is maximally compatible with the previous-generation language, there are still some differences between these languages.
