I don't understand completely. So they're posting bids/asks outside the NBBO on separate exchanges and using a counterparty's sweep to quickly turn around and dump shares on the inside on whatever exchange happens to have the most liquidity? What's a good stock to watch this behavior on?

I was reviewing your ROK/WY trade. I'm trying to figure out if you are calculating correlation by raw prices or returns of prices. I don't understand what in the real world this correlation represents. Do you construct factor models to regress against the indices and then take the...

How does GETCO do business exactly? I've gathered a few details. - I've googled around for them and their speaker's descriptions speak of "razor thin" profit margins. I missed one of their presentations at my undergrad school. I'm assuming they're basically high-speed stat arb and...

Ain't that something? Truly Uh-merkin.

What conspiracies? It was well known in 1953 who the Iranian government was overthrown for. It's well known now who is getting the various contracts and who is building our embassy. It's not a "conspiracy theory" just because the MSM doesn't report about it in the US. Our media didn't even...

The reason people say "live a little" is because it's beneficial to the economy to be a consumer and not a saver. The pain of being a pauper and not being able to take control of your life when you -want- to take control of your life is far greater than passing up on a slightly nicer place...

You'd be right, if our intentions were to either remove WMD or promote democracy. Neither of those were the intentions. If they -were- the intention, we wouldn't be gearing up to maintain an embassy there the size of the Vatican. The US never promotes foreign interventionism on account of...

Wow, yeah man -- I'm just like you, same timing and everything. Don't mean to ramble, but I've been thinking about this one a lot. I agree with the guy who mentioned rent yield; however, I've been considering buying some raw land and throwing down a trailer on it and living extremely cheaply...

Oh, I agree. However, people tend to vote for politicians based on the idea that they are getting some sort of ideological package -- much like as if they were ordering a cable package for home entertainment. Imagine ordering digital cable with a great sports package but then ending up with...

I'm voting for Bob Barr; however, before I decided to vote for Bob Barr, I gave Obama some serious consideration. However, Obama flipped on FISA. That's when he lost my vote, never to be regained.

Replace homeless guy with "irresponsible lenders" and "the owners of the federal reserve" and the story makes even more sense.

+5, Would read post again. I work in equity derivatives space and am forced to use C and C++ and generally connect directly to the exchanges. I'm a low-latency nazi, but I tend to agree with the posters who suggested languages like C# and Java. Why? Because if you're a retail trader...
