The bids and offers were not "real". As opposed to imaginary?
Even if the bids and offers were away from the market, a large sweep order could fill the submitted prices and there'd be no way to get out of the trade after you were filled.
I have a long history with exchanges being much closer to regulators. The exchanges portray your prices as somehow immoral. The SEC had a leaked report on the AMEX options market, where the SEC caught the AMEX falsifying documents to cover up how the AMEX screwed the public on option fills. It didn't matter, even with the regulators own words, because the SEC exists to protect entrenched broker-dealers, so that SEC personnel can later get jobs in the industry.
I've read about bots whose purpose is to fake out the other bot, and/or get a feel for the size of the opposing orders. Everything is fair game.
