Disclaimer: I work at an HFT shop. A very basic question: if you wanted to buy 100 shares of MSFT right now, who takes the other side of the trade? High Speed Trading does NOTHING for owners, investors, the company or anyone but the trader

Care to elaborate further?

Just a minor point, but I've never seen a 75,000 lot rip through ES in one order.

Trying to understand why an algorithm made a trade at a certain price is practically impossible. Assuming that these algorithms are profit seeking (and not utility seeking, as in trying to transfer risk), the short answer is: because they t

I would gladly pay to use this service. Maybe they should monetize it with a subscription service.

I guess the question is, why does this theory deserve to not be dismissed? There are (pulling a number out of my ass) tens of thousands of theories on anything and certainly not enough resources to test them all. I think the burden of proof

The team also found an unusual pattern in the way the cells changed colour under UV light, known as "fluorescence behaviour". They said it was "in remarkable correspondence" with red emissions from the Red Rectangle planetary nebula

That's almost a direct quote from Adam Smith's mouth from a talk he gave at MIT startup bootcamp. I don't have the link to the video at hand, but I distinctly remember him saying, with a pause for emphasis, "Xobni does not solve the email

Xobni doesn't claim to solve the mailbox triage problem. That's a really hard problem.

My apologies, it was in (mathematical) physics. Though, from the wiki article: Sir Michael Atiyah said of Witten, "Although he is definitely a physicist, his command of mathematics is rivaled by few mathematicians... Time and again he has s

Are you implying that need-blind admissions allows universities to increase tuition? The only two ways I could see raising tuitions as justified because of this is: 1. It costs more to provide grants to poorer students. 2. More competition

That's really interesting. Out of curiosity, why do you think it's so hard for you to get a job in the industry, despite graduating from a well regarded program? Or maybe to rephrase, since you didn't say didn't get a job, why is having a w

Ed Witten showed mathematical precocity at an early age: http://www.maa.org/pubs/mar04.pdf (page 28). Without exposure during his youth, it's almost impossible he could've completed a PhD in math at Princeton.

Wow, that dialpad looks remarkably like the iPhone dialpad.

To be honest, I don't think I (or a majority of people) could learn theory without help. Math and theoretical CS are pretty hard. I can't count the number of times that I've had questions that only a TA could answer for me. To be fair, ther

Who are you to say how I should spend my time?

So they shouldn't be interested in learning about it?

"Useful" is a particularly subjective word, and shouldn't necessarily be the metric by which we measure the opportunity cost of our time. Many advances in the world that you and I take for granted are the direct result of pursuit of knowled

A smart person will clearly delineate what he does and doesn't know, especially in mathematics when statements are either true or false. Terry has stated before he's far from an expert on this subject, and everyone is very well aware of tha

Or, more likely, there are lots of good ideas that can be applied to other difficult problems.

If so, then they should be disallowed. Regardless, they accounted for for a tiny fraction of all trading volume. I doubt most HFT firms make much from them. Saying HFT is bad because of flash trading is like saying driving cars is bad becau

At my firm, back office and trading are very, very different. I would advise you to stay away from back-office if you're not interested in that. YMMV

Who is getting unfair information? Do you mean flash orders? Those no longer exist (for which I'm glad also). HFT in general though doesn't take advantage of unfair market information.

Aside from the part about "bitch", I agree with pretty much everything zackattack said. Key points: 1. On your second exposure, things will make MUCH more sense. It's just how I've found the mind works. The first time you read something, yo
