this weeks Barrons says hft are a pox on the land.
Quote from brownegg:
You read Barron's? Let me guess: Abelson is bearish.
Barron's has to be amazingly profitable... AA has written the exact same editorial for 15+ years, and then they ask a bunch of index-underperforming mutual fund managers what they think, then regurgitate LOLWEEKLY price info. Then there's always the sage wisdom of the Strike Price or whatever.
I don't think I've seen the inside of a Barron's in the last ten years. That's really the best you can do?

You didn't ask any questions, you simply trotted out the hft talking points.
Now go back to data mining C and SIRI.
Quote from WinstonTJ:
Did you read the article? Do you know why and when a quote is generated and what constitutes a new quote? Do you have any clue how many quotes there are on average in a second compared to that day or are you just using their numbers as a blind reference because they seem high?
Quote from stock777:
that study claimed there were thousands of quote changes in a second.
if you'd like to defend that , go ahead. you just prove my thesis. Al Capone also liked to defend his rackets. In fact there isn't a scammer or thief out there that would not put up the same defense you do. "You don't understand, I'm a good guy, just making an honest living"
During May 6, there were hundreds of times that a single stock had over 1,000 quotes from one exchange in a single second. Even more disturbing, there doesn't seem to be any economic justification for this. In many of the cases, the bid/offer is well outside the National Best Bid/Offer (NBBO). We decided to analyze a handful of these cases in detail and graphed the sequential bid/offers to better understand them. What we discovered was a manipulative device with destabilizing effect."
