Many many years ago I worked at an ISP and I remember getting emails of the form: From: manager@corp.com To: minimax@corp.com Subject: When you get a minute We got a subpoena to provide information about <identifying info

You are conflating market making and latency arb, which are not the same thing. All of your points apply to latency arbitrage and you haven't said anything about market making. As long as there are profitable arbitrage opportunities, people

We use technology to improve efficiencies in every industry in the world, but when we use technology in the capital markets people freak out. I don't get it.

Some tweaks to your explanation: The thinking behind this theory was that a simulator would keep adding liquidity to a fake market for testing a market making algo. If you're testing a market making algo (i.e. to participate in NYSE's RLP

I was much more cynical about new technology products before I tried to build and market one myself. That shit is hard, and most of the peanut gallery here one HN has no idea what it takes.

This seems like a good idea. There are a lot of wealthy traders in NYC, but the richest guy in the city is the one selling all the traders neatly packaged financial information.

I agree with #1, but I don't think the also/too redundancy is ungrammatical. It's superfluous but syntactically valid.

What part of the sentence do you think is ungrammatical?

You must have missed the part where the NASDAQ bug caused about $60MM in losses whereas the subsequent price decline has destroyed $40B in market capitalization. You can lose your shirt in the stock market, but that's been true since long b

The exchange matches buy orders against sell orders. In this case they were matching buy orders against sell orders that had already been cancelled (which is not something that should ever happen). NASDAQ stepped in and took the other side

I have heard of the Ballmer Peak, but for me even a single pint of beer totally kills my ability to write code. My creative peak seems to be the first few hours after a really good night's sleep.

I think a lot of people get bit by small stdio buffers and switch to mmap, not realizing that read() based solutions can be improved greatly by better buffering strategies.

I have never worked a whole day from a coffee shop, but I do like to spend an hour or two after lunch in one of the several coffee shops in my neighborhood. I'll order a coffee and maybe a sparkling water. I find the change of scenery helps

How big of a tree was it and how big were the nodes? I don't see how you get any locality of reference for a large enough tree, and you certainly don't get any of the hardware prefetch. To get any benefit out of this I think you need multip

Why can't I walk up to the stock market and buy a single share of Facebook? If you have a membership on an exchange, the marginal cost of buying one share of FB would be the liquidity removal fee of $0.0030 (three tenths of a penny)†. But

Sorry I should have put a disclaimer that I was talking about trading in the US. I'm not as familiar with retail trading in the UK. In the US you will typically pay between $7 - $10 per trade for stocks (regardless of order size). These ar

The thing is, it's pretty hard for an ordinary person to buy a share of a company. You usually need to be able to buy a large quantity of shares, pay for a trading account, try not to get ripped off with various fees, and deal with taxes.
