MetaQuotes Language 4 ( MQL4 ) is a domain specific language for programming of trading strategies built-into a MetaTrader Terminal, a client-side trading software.
This language allows one to create own Expert Advisors that make visualisations, trading management augmented/automated and are perfectly suitable for implementing of one's own trade strategies.
Besides, one can use MQL4 for creation of one's own Custom Indicators, Scripts, Libraries and more complex, distributed/grid processing, solutions.
The structure and syntax of the language is very similar to C.
New MQL4, forcedly injected in about 2012, added new concepts, borrowed from not so widely accepted MQL5 domain and legacy MQL4 codes started to have two different (!) compilation/execution modes, depending on a use of a #property strict directive. Also some internalities of the MetaTrader Terminal platform started to be changed, resulting in a need to massively redesign / re-engineer code-base, due to injected changes ( having no other option but to re-design DLL interfaces and much more - string type ceased to be a string - a NULL terminated block of chars, to name just few )
The official compiler can be downloaded from here.
