Trade Functions
This is the group of functions intended for managing trading activities.
Trading functions can be used in Expert Advisors and scripts. OrderSend(), OrderClose(), OrderCloseBy(), OrderModify(), OrderDelete() trading functions changing the state of a trading account can be called only if trading by Expert Advisors is allowed (the “Allow live trading” checkbox is enabled in the Expert Advisor or script properties).
Trading can be allowed or prohibited depending on various factors described in the Trade Permission section.

What’s new in MQL5
Added the functions for working with orders, deals and positions to conduct trading operations. An order is a request to buy or sell. The order execution leads to a deal resulting in opening, modifying or closing a position.
If you develop trading robots, pay attention to the new OrderSendAsync function intended for asynchronous trading operations. This function is executed in less than 1 millisecond (it does not wait till the trade server responds to a sent request) and returns control immediately. Low network costs, high Depth of Market refresh rates and asynchronous order sending accelerate trading operations dozens of times. For intraday systems, the speed of trading operations can be a key factor.
