I am a big fan of Edward Tufte.

Are you saying the SIP runs on the best hardware/software available? I want to get that cleared up before moving on to a new topic.

"Flash Boys: Not So Fast" is an absolute joke, and this is known by everyone on Wall Street with a functioning brain (I'm guessing you know this too). Your name is all over this th…

Wealthy friends with promises of a nice job (and other things)

Pretty sure NYSE's ancient creaky FIX gateway is infinitely faster than the NYSE ARCA gateway - as the latter, while more network efficient, isn't going to ever take your packets t…

He's right - if you weren't part of the group that was paying them over $100M/year in fees for "real-time" data and you weren't buying or selling stock in 2008, 2009, 2010 and 2011…

Are you from Citadel? Would you trust Wall Street to give you the best price on anything if there was no way to verify it? There is no way to reasonably know if you are getting the…

Excellent question: they were ECSTATIC to pay $5M Covington and Burling - who represented the NYSE in this matter, used the paltry $5M fine as bragging rights in their year end let…

I don't have a name for that chart. It's a customized display I wrote that I found makes it easiest to view quote spreads and trades from multiple exchanges. I write in "c" combini…

It happens all the time (ALL. THE. TIME.) and have documented dozens of examples. There are links to many of those examples on that page (fantaseconds). I've also posted many examp…

I was ignored by the Trading and Markets people at the SEC, but not ignored (obviously) by the Enforcement people.

Yikes. Lots of misinformation here. First of all, this has nothing to do with High-Frequency Trading. It's about the NYSE not delivering a product (SIP real-time data) while collec…
