Hedging
Hedging - The common trade accounting mode in Forex (also used in MT4 and optionally in MT5). Hedging allows opening multiple orders or positions in any directions for the same symbol. For example, you can have both a long and a short position on EURUSD. MT4 always uses hedging; MT5 supports it as an option. By default, MetaTrader accounts are “hedging mode” (each trade is independent).
