Charts and T.A. doesn't make any sense to me I'm not so good. More badly with indicators.
I'm trying to understand how to read the DOM. I mean the prints total volume.

which is the difference between flipping and spoofing ?
Why Tom B ? He was the best MM in the Bond Pit.
Thanks.

Spoofing is simply submitting limit orders that you will pull before they get filled.

Flipping is a process of spoofing one side of the market to make that side look strong whilst sucking up contracts on the other side. So you might spoof the offer to make the offers look strong, this encourages people to sell and the spoofer is also sitting on the bid with an iceberg order absorbing all the selling.

When the flipper has had his fill, he does a 'flip', he pulls his offers, stacks the bid and starts firing in market buy orders.

Those that sold know they are toast and they bail out (by buying) and the market pops up.
