After Hours Trading YM Futures

Pay close attention to the Level 2 quotes during the after hours trading on the Mini Dow jones futures contracts (YHM9). There is a seller who pushes the price lower by flashing 15+ contracts on the offer when there is a bid-ask spread of several points. This action will be easy to identify because after flashing his size, he closes the spread by offering 1-3 contracts 1 point lower than what his fake offer is. He then pulls his small fake offer to show his major offer, then re-posts his smaller fake offer. As a level2 game this is crucial becuase it immediately creates real sell orders for the SCHW clients because of thier complimentary level 2 program.
