MetaTrader has been around since 2005, and is an incredibly popular trading platform. It was founded by MetaQuotes, a software company. As its name suggests, it has multiple versions, with MetaTrader 4 being the most common. While Metatrader 5 came out in 2010, most users have stuck with MT4 instead. While it offers a wide range of features, it notably has no direct customer service.
