MQL5 is a high-level programming language, which was released by MetaQuotes with the MetaTrader 5. MQL5 was created from scratch and is not an updated version of MQL4. Syntax of MQL5 is close to C++ and allows to create autotrading applications[1] in the style of object-oriented programming (OOP). MQL5 is designed to create automated trading solutions for algorithmic trading: these are trading robots[2], expert advisors and technical indicators. The applications are created using MetaEditor IDE, MQL5 Storage version control repository and MQL5 Community with free CodeBase.

History

In 2010 the public beta-testing of the MetaTrader 5 trading platform started. MT5 has expanded trading opportunities with the use of trading robots and expert advisors for management and analytics of trading accounts without human intervention.[3] The key innovation is the new MQL5 language used for programming trading strategies. The new version of MQL was created from scratch as a new object-oriented programming language. New types of data, events and chart operations have been added to MQL5. The introduction of the MT5 platform started slowly because of the complexity of the transition to a new language for brokers. Due to regulatory changes, the transition to MT5 and MQL5 accelerated.[4]

In July 2014, MetaQuotes revealed the possibility of fulfilling freelance orders for developers of trading solutions in the 'Jobs' section of the MQL5 Community, and receiving a fee through the internal payment system.

In 2017 MetaQuotes released updates for MT5, aimed at creating synthetic financial instruments and simplifying the creation of applications for algorithmic trading. In addition to the main MQ5 program file, a separate MQPROJ file is used, which stores the program settings, compilation parameters, information on all the files used. MetaQuotes have also added the feature for distributed teamwork through the MQL5 Storage and the MQL5 Cloud Protector mechanism for additional protection of trading robots created in MQL5.[5]
