Quote from rufus_4000:
Why is this surprising? Almost all option MMs trade based on theoretical prices, once your ask is below their ask, the automated MM program determines whether the spread still need to be maintained, if not, then it will cancel its ask (not need to make the market), based on the fair-value algorithm, its bid is farther from "fair-market" than your ask, so the MM edge is still maintained. Once you cancel your ask, their MM determines the need to create a spread, so the new ask get placed.
As most of the MMs have switched to automated MM algorithms, it is pretty impossible to "sucker" a MM into a situation where their order is "stuck", the normal turnaround time for the MM programs is around 20 ms (tops), especially with CBOE's RMMs, PCX Plus, etc.
I didn't think it was surprising, just interesting. I agree, I'm very close to the CBOE and on very fast lines, yet I can't come anywhere near getting it. I assume that doing it from another account would be illegal, no?

...but the practice you describe is illegal and, if you somehow managed to get executed on your buy, you and/or your executing broker would get fined by the exchange and probably get your trade busted.
