One of the things we all know we ought to do is to share in other people's joys and sufferings. As St Paul says in Romans 12, "Rejoice with those who rejoice, weep with those who weep."
It's a rather uncomfortable fact of common experience that #2 is a lot easier than #1.
Cheers

I don't know the details, but there are companies that have set up just next door to the NYSE and such, to shave milliseconds off their transaction delays. They spot tiny differences in buy/sell opportunities and trade stocks for literally seconds.

This, done by hundreds of players, could have interesting instabilities.
This sounds like pure parasitism to me, and soaks up some of the best math grads in the country. A small transaction tax would kill this off.

-- His dot sig is much like yours, except that he prefers to align himself with MIT, which he considers to be a higher power, and why not? He's proud of his Alma Mater and feels a bond there because of what he learned from people whom he wouldn't have had access to had he been in another school. You, on the other hand, consider yourself a higher power and scurried through school with the sole intent of getting paper. It seems, though, you weren't listening when "infinitesimal" was being discussed.

The subject is 'subjective', so I'm inclined to agree. I was a self-learner cuz I worked. I did the exams when I felt I needed to and arranged appointments with Profs at mutually convenient times, always well prep'd. For labs, I'd start ~7:30am fresh and burn-out by 11:00, and consolidate. Not sure what alphabet I can hang off the end of my name. For fun I'd assist the Profs in their personal research.

I don't believe you are ever "taught", you either choose or not, to "learn" what your environment presents to your view.

Yeah, but learning from some teachers is easier than learning from others!
Indeed. Speaking of things that keep you going... how's the hip these days? I happened to be talking to an orthopedist the other day, and he was mentioning that there are so many new types of artificial hips available now that, while they're all trying hard to outlast the traditional ~10 year lifespan of the metal ball/plastic socket approach, they haven't been around long enough to really know their longevity yet.

My sigfile is actually a search engine experiment. It was suggested to me by, well, someone.
No, I wanted to learn engineering: physics, math, electromagnetics, thermo, materials, mechanics, circuit analysis, signals+systems, communications theory. Everything considered, Tulane did a pretty good job of teaching that stuff, probably about as well as any undergrad school would. Electric Machinery and Psychology and Beginners' Tumbling were great, too. English, economics, philosophy, and chemistry were probably about as bad as anywhere else, too.

I definitely agree with you Bob. I spent two years at community college before transferring to UBC (which I think Phil Hobbs has given a thumbs-up to) to complete my BASc. While the instructors at UBC were good, on average the ones at the community college were better. I suspect that had I gone on for a Masters or PhD, the quality of instruction might have improved.

Over a decade ago I worked for a day trading company. They always wanted the best, fastest and latest trading software to stay ahead of the competition. The problem is the software developers sell to everyone so you get a never ending race. Still, losing money is easier than making money. Judging the state of mind of some traders I often thought about removing the handles that open the windows.
Its not only about riding up and down small changes in share value but also moving shares between various stock exchanges. Some shares are traded on several exchanges so they need to be transferred from one exchange to the other. Due to differences in demand the prices also vary between one stock exchange and the other so a profit can be made.

A few weeks ago I was chatting with a lady who executed a project for a major bank- they used a bunch of double-PhDs and such like to set up kind of an arbitrage scheme with physical servers in various locations and sophisticated software to do high-frequency trading (she explained the underlying concept to me-- it is actually pretty straightforward and the use of it long pre-dates computers)- the project cost many millions of dollars.. it paid back 100% in just HOURS. There are unbelievable amounts of money in this sort of thing.

Both to win and to lose. When they win, it's theirs. When they lose, it's ours. What's not to like?
The late unpleasantness of 2008 wiped out more than the entire historical profits of the entire banking industry, the world over.

it depends. Let's suppose there exists an optimal sequence of trades ( fair assumption? ). The question then becomes whether an experienced trader and a programmer together can make a "meta" that approximates that sequence better than just the trader running "on instinct".
Doing this would require the trader to be the one on the hook, with the programmer being as ignorant as possible of the larger view of the thing. The programmer is there to encode the widget for the trader, nothing more.
SFAIK, markets still exist to produce an optimum "transfer function" between buyers and sellers, mainly by varying price. Trading is a win-win, even if Black-Sholes & the Efficient Markets Hypothesis cause misbehavior or don't hold over some domains ( fat tails, Black Swans).
I'd think the biggest risk would be hubris - the trader/programmer combo start thinking their poop don't stink. The market would then pounce on that error, and they'd get badly hurt.
SFAIK, the autopsy on the Flash Crash from 2010 says it did not cause anything more than a convergence on too-low prices for a short period of time. IMO, I think there was a shortage of liquidity, and that we've run on the ragged edged of liquidity
*in general* since about 1999. I think that's political, mainly. Somebody took the short end of that and made out like a bandit...If you look at how firms managed cash in the 1950s and now, it's breathtakingly different.
I don't think it's *particularly* parasitic. Math grads gotta eat, too. Then again, I consider prices a public good. I don't know of any reason that higher transaction costs do anybody any good. If it turned out to be a good revenue generator, then I'd be for the tax.
