Then you really need to go back to trader school. When a real investor places a real bid, and the MM, jumps that bid up, they are doing it for one reason only. Now go look at the short list, etc.... and its pretty clear. May nor be 10K shares, but they do this for 100 shares, because its all computerized and automatic. A few keystrokes in the AM, and the computer knows the parameters to trade within. And they have sophisticated programs with built in protection mechanisms.
But if you want to stay negative, that again is your choice.
