Correlations will tend towards 1 when using a large-enough time frame. On a microstructure scale, correlations go haywire in liquidity distress.

Which part of "buy and hold" includes "sell when it goes down"?

You're conflating two things (in my mind). L2 is very useful to people like me. If it's useful to you, you should be able to handle spoofing. The "average investor" doesn't need L2, and doesn't care what it s

They don't get unnecessary volatility unless they're paying attention to the order book all the time. Realized equity volatility is MUCH MUCH MUCH lower in the era of HFT. Yes, "flash crashes" exist, and normally becaus

Your question is exactly correct. As long as they are real orders, with real risk of being executed, there should be nothing at all wrong with this behavior. If people are so stupid as to move their orders trivially based on others'

A senior/experienced person offering potentially-qualitatively-better "stuff" in the realm of something like code isn't the point. I'm sure there are exceptions, but in general no one is saying, "Let things be

If we throw out, even if momentarily, that there's more to success in the markets than pure luck, then people who have succeeded have done so in a very pure way: you can only make money in trading by being right. When you're righ

Soros is definitely weird at times, and he is almost always too-certain. But your negative characterization of "billionaire investor" is a disservice to you and him. Rather than learn about the world by selling products or climb

You are certainly right that it was fun. But basically the hypergrowth of the '90s was borrowed from the future. All policy was good if GDP grew. Greenspan noodled on the problem--"irrational exuberance"--but unfortunately

Does it not resonate? That line hit me like a ton of bricks. I'm almost an OO fanboy, but that is a _very_ good point.

If it's $862m, last I checked, it will take them about 30 hours to bring in the necessary revenue--if they want to pay out of profits (I'm totally guessing here, what are real net margins on their hardware? 15-20%?), it'll t

I can't upvote this hard enough. OP is right in my mind, but.... I'm straight (and divorced), and we got married for many of the same reasons that LGBT folks want to--it makes sense. Visitation rights, inheritance, tax treatment

All true. Also been true for ~7 years, so maybe it doesn't matter much.

It is so, so infrequently that I get to say this about something HFT-related on the internet: fucking awesome, dude. There is actual information here that is of use and doesn't mislead. It's amazing. edit: s/dude/guy-w

The latter is somewhat true, and probably unavoidable at this point. "The cat is out of the bag", so to speak--markets can't just go back. The problem is that the incentives are so wildly disproportionate. If a really smar

I'm in the "professional automated trading" space. This is by far the most common vendor mistake. "We make trading simple!" is pretty much a surefire way to mediocrity at best. "We make tax law simple!"

Congrats on your success--you have the best kind of problem. 1. You have a working product--do not do a full rewrite. Rewriting has so many pitfalls in the best of cases, and if it's just you, the context switches between the "old" (which

The children here are potentially misinterpreting this. I don't see this comment as being judgmental. The fact that Apple has accomplished this does NOT mean that the poster is saying Apple adherents are mindless drones or fanboys. What's

I think you need to drink something other than the Kool-Aid. Java has its warts, but all languages do. Get over yourself.

How about none of the above? Directly to the CEO is the only thing that makes sense. And the CEO had better be focused on Product (or Service) Management above all else, and all those other things should report INTO the PM organization. E

(Of course) the data won't be free. They don't get it for free--"tape" fees are a major source of exchange revenue. (Although it's possible some delayed feeds may be available, etc.)

I don't agree. Giving 30 books vastly increases the chance that any given reader can find the "right" 20%. Your 20% might not be mine; although I would find it interesting if you posted your top 5 books, I'd rather see the 30 that you rea
