Interesting. "flashing" bids is a well known technique of pro traders and brokerages and so forth. As stated, they usually get flashed for short periods, then vanish.

Has all kinds of stuff behind it usually- shorting, trying to fill orders at a certain price or price range, manipulate the stock price sometimes- like the same firm being on both the bid and ask sides of a trade? If it's a real bid just parked there- it sure isn't getting filled then, which means no one right now is willing to pay even the bid price for about $15K or $20K worth of stock, IMO?

Who knows? NITE (Knight Capital) is a huge handler of order flow- been around forever (I think bought-out not long ago, owned by someone else now, I think they trade as KCG now on NYSE?) and one of the original big electronic network inventors, inventors of high frequency trading networks, all kinds of stuff. I remember when they were a mega high flying stock, as Knight Capital (I think NITE was even their symbol) yrs ago prior and during the yr 2000 mega boom- then got busted and in all kinds of trouble for stuff, then the market collapses of 2000 and 09 I believe- they're not the mega big deal anymore like they were back in the day. But they're still a huge, real big big handler of order flow- that's for sure.
