MT4 is designed to be used as a stand-alone system with the broker manually managing their position and this is a common configuration used by brokers. However a number of third party developers have written software bridges enabling integration with other financial trading systems for automatic hedging of positions. In late 2012 and early 2013, MetaQuotes Software began to work towards removing third-party plugins for its software from the market, suing and warning developers and brokers.
MetaTrader provide two types of trading orders, Pending Orders and Market Orders. Pending orders will be executed only when the price reaches a predefined level, whereas Market orders can be executed in one of the four modes: Instant execution, Request execution, Market execution, and Exchange execution.
