If you watch a price ladder closely you will notice what appears to bid and offers in a fairly tight spread. There are numerous ways to fool folks into believing these bids and offers are legit. Things are not what they seem.
Stop making silly excuses. Some of us really live trade emini's everyday, including NQ and MNQ.
The market makers pulling bids and offers is a thing that happens, but not enough of an issue to effect your 2 lot trading system.
