The largest community of developers and algorithmic traders MQL5.com celebrates its 17th birthday on November 11, 2021. The community history began from the launch of the MQL4.com website which was named after MetaQuotes Language 4, the integrated programming language for developing indicators and trading strategies for the MetaTrader 4 trading platform. In 2010, following the release of the new MetaTrader 5 platform and MetaQuotes Language 5, the community turned into MQL5.community.
