As scheduled, MetaQuotes announced that MT4 Build 600 has gone live yesterday evening. The new build brings MetaTrader 4 users access to the company’s EA and other trading apps marketplace with the arrival of a new ‘Market’ tab on their platform.
In addition to the marketplace, Build 600 contains a major update to the MQL 4 coding language that is the foundation of the platform’s automated trading and custom indicator development system. With the update, MQL 4 becomes closer in language and functionality to MQL 5. According to the firm, existing MQL 4 files built previous to the update will continue to operate correctly.
However, there is an ongoing rumor that some expert advisors and custom indicators are not working properly or not showing on the new MT4 Build 600, hence such EA’s and indicators needs to be re-programmed by the programmer to the new language so it can work properly.
