In live trading, order filling depends on the broker API. By default, the behavior is the same as in the backtest ("fill-or-kill", i.e. no partial fills). This can be changed with the SET_ORDERTYPE command. Partial fills are allowed for IOC ("immediate-or-cancel") or GTC ("good-till-cancelled") orders.
As far as I can see SET_ORDERTYPE is not supported by the MT4 bridge, does it mean partial fills aren't possible through it?
