These guys make/move the markets in the USTs and I know they watch for the my clearing firm's number and match our fills real time.
The most obvious example of this abuse is at night: We will get to a way extended low in the outrights, my coworkers and I (who aren't small for the night market) will get in and then the market maker will hold the market down, repeatedly snapping the TY back sellers at the low (sometimes for hours) until we all finally either scratch or pay down in the other markets. As soon as we are all hedged or have scratched the outright to him, in literally seconds he will turn the market around taking it minimum bid bid.
It is really disgusting and disappointing that the CBOT lets this go on. But you know they don't care about the local. The market makers at night have increased the volume by about 100% in the last year. The CBOT loves it.
