Nanex ~ 23-May-2012 ~ BOKF Quote Attack
BOK Financial Corporation (BOKF) has a market cap of $3.82 Billion. All day long, the
quote spread violently shifted anywhere from 1 cent to 75 cents and everywhere in between.
Sometimes the spread would change one cent at a time, from 1 to 75, in the same second.
Maybe there was some loop in a news feed and the HFT machines, which lack basic common
sense, accepted the same round of news stories a thousand times a second. That could
But more likely, what is going on here is that the symbol BOKF is processed on
the same network or machine as the target symbol, and is just an innocent victim. You
see, you can overload ANY network or machine anytime you want by just giving it more
work to do. Jam quotes in BOKF, and instantly all symbols processed on the same network
and by the same machines suffer, equally. Well, not quite equally - because there's
often more than one feed. Some are so hush hush, all but the best exchange clients know
about them. So jam the other guys feed, and pick off his stale quotes! Only the other HFT
guys know, and won't tell the SEC because they are doing it too. Each HFT thinks they
are outsmarting the others. Meanwhile, our SEC is a decade away from having capabilities
to even begin to grok the disturbing heights that manipulation has reached. It doesn't
help any that there are probably a dozen reporters in the entire world, total, that
could tell you the difference between a trade and an order. I wish I were kidding.
There is a world of difference between having
the capability to cancel a quote
in a millionth of a second..
..and canceling a million quotes every second.
It seems the worst of HFT doesn't grasp this basic grade school logic. Oh the drama.
"If we can't cancel our quotes in a
fantasecond, we are going to take our ball home and no one
can trade anymore and the financial world will end as we know it." Please. What they
really mean is they want to be able to cancel quotes faster than the other guy. The
slowest gets "picked off", which means their orders get executed. They end up buying
or selling stock. Truly an end of the world scenario. We should bail them out.
So dear reader, entering and canceling quotes, as in the case of BOKF, has absolutely
nothing to do with wanting to buy or sell this stock. It has everything to do with some
nefarious HFT trying to improve the odds of picking off a less fortunate trader.
And to be sure, this is just one form of bad behavior that has infested our markets
because there is no authority figure to provide clear and consistent guidance. No one
to tell Johnny's computer to stop mugging Sally's computer, because well, they are just
computers, right? Again, I wish I were kidding. Every imaginable way to prevent
the flow or pervert the quality of information, has been, is, or will be tried. It's all just
wires and computer chips, right? Besides, no one is looking, and after all, "Money is Money"*.
We call this the anti-Stock Market.
