Partial fills with MT4 in live trading?

Quote:

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?

That depends not on commands, but on the broker. According to experience, MT4 brokers normally do not fill orders partially.

Does it mean that if the broker supports partial fills trades will be filled partially automatically? I saw there is just a new variable OrderDuration. What is its default? If 0 does it mean the trade is cancled after the first fill? Are the filled lots available through TradeLots?

OrderDuration is only for APIs with limit orders, not for MT4. By default it's 0. I have not heard of partial fills with MT4, so I don't know if they can really happen or not. If they happen, then the fill is available through TradeLots.
