Quote from MarketMonk:
Okay, I will bite.
As far as I am concerned this is a silly question. Yes, at times you can (or so it would appear) move the price with a single contract. Albeit for a nanosecond.
Any of the futures contracts trade enough volume that even if you did move them, they could be pushed right back to where they started from (and then some).
So if you think you can come in with a 100 or even a 1000 contracts and make a dent such that you get something started, in order to cash out later, think again.
