MetaTrader 4, also known as MT4, is arguably the most popular CFD & forex trading platform among non-professional traders today. Although the platform was developed all the way back in 2005, it remains hugely popular in the trading community to this day largely due to the unique marketplace of trading algorithms that can be bought and sold within the platform.
The majority of CFD brokers offer the MetaTrader 4 platform as at least one of their platform choices. Among those, there is also a fair number of brokers that offer the MT4 as their only platform. Usually, the platform is used in a downloadable desktop-based version, but it also exists in a web-based version that can be run on any computer.
