Expert Advisors
Expert advisors are a type of algorithmic bot used on the MT4 and MT5 trading platforms in order to automate trading strategies and deploy them without human intervention.
They are created using the native languages of MT4 and MT5 (MQL4 and MQL5, respectively) and can be tested and tweaked using native features that MT4 and MT5 come pre-loaded with.
A very active community of developers has grown up around these two trading platforms since their release, actively building and testing these bots on real markets and sharing their insights with others.
