If you place a limit order at the market, it gets filled. Sometimes you get a wide mkt and a fill needs 2 or 3 ticks from where the inside mkt was 10 seconds ago. Its why I never use mkt orders - but yes, mkt order you get filled asap, but maybe not where you thought.
QG is even worse sometimes, as it can widen out to 4 or 5, if not more ticks, for the inside mkt.
