All it takes is for them to cancel to order to remove any supporting or resisting order.

They do that stuff all the time on Level 2 for nasdaq stocks and I'm not surprised someone is doing it for the YM as well.

But also think of it this way, at 450 lots, that's $2250 per tick. Were they trying to really sell rather than buy knowing that "newbies" would see that huge bid and go long the market.

We'll never know, just speculate because they may have been offering the market on a smaller size.

There was one thing I noticed a while ago, the levels were pretty thick for about 5 levels below the best bid around 200 lots each level, that support held, I don't know what the tape did, but prices rallied from that point.
