If you get a chance, check out Flash Boys by Michael Lewis. It's not really 100% accurate, but it definitely introduces a lot of the terms and the overall topology. He makes HFT's out to be evil villains which really isn't true, but it's a pretty easy read and at least shows some of the dark...

There are something like ~100 "trading venues", most of which are dark pools. Most brokerage houses run their own. So if I want to buy 100 XYZ and you want to sell 100 XYZ and we're in the same brokerage, if we both smart route, the order will fill without ever leaving the brokerage. The venues...

Yep. I've also found that when/if you decide to make yourself bigger and go the hedge fund route, the people putting money in very well might shake your hand but they'll defer to their counsel for an approval stamp, which usually means an independent audit. No sales pitch can match a multi year...

FX scares the shit out of me, both the way the "markets" (which aren't even markets) move, the lack of regulation, the full-retard leverage, and the insanely high speculative nature of it. It's actually worse than a zero sum game because of the spreads. I did the math once and something like...

I used the tradier api for a while (with c#) and can offer up the following points: - Exchanges and instruments are quite limited. Basically US equities. No futures, nothing outside the US. This doesn't seem like an issue until you start to really build out an operation, at which point the last...

I'm on the fence with the PDT rules. Overall I'd kill the rule because it's a free market and it's not like we're stopping people from buying bullshit at Costco or amazon.com: it's your money. I sort of wonder what the impact would be on the equity markets, but I imagine that we're talking...

Same for me, although I have a couple of hundred bucks in etrade and tda accounts as well just to poke around on the platforms. Vanguard really is phenomenal, and IB isn't perfect for trading but it's pretty close.

That website looks pretty hoakey.

What I've found really weird is the obsession with getting a quant job. I've always worked under the assumption that my results matter. If people aren't beating down my door to hire me, that's my fault. And honestly all interview questions aside if you can drop a P&L down on someone's desk with...

Couldn't agree more. I think it's equivalent to saying that to be a good writer, you need to write in some particular language. You need to write in a language that you're very good at, and that best allows you to express your ideas properly. Nearly any decent programming language, and probably...

I like having Alpha.[ModelName] for name space organization. All the alpha models exist as their own class (with sub classes if needed). I like it because: - I get "full" functionality to create a model. Whatever is possible in the language/platform/framework, I can use. - Alpha models are...

I use GARCH as an overlay to overall volatility measurements. In normal-speak, using it in concert with something more straight forward like VIX. If you're long (and/or trying to avoid being short) volatility it's more predictive than a single variable. "Rule Based Investing" by Chiente Hsu goes...

Make sure to drop by stackoverflow and let them know your feelings, considering that the whole stackexchange network is c#/mvc/mssql.

Personally I don't find much use in it, primarily because of cancellations, ice bergs, and dark ice. I think when people see the order book the don't realize that they're not seeing the order book. I think a lot of folks who use the book are thinking back to previous iceberg / hft days.

One tough part about hedge funds is getting the clients. You're not selling lemonade, you're asking people to trust you with a lot of money. And anyone with money to invest in a hedge fund probably has been approached by dozens of other brokers and managers. You're up against a lot of well...

Whatever your price, name it, I'll pay it.

I can't wait until the next big correction so they can dust off the prophet du jour who will be hoisted up on the shoulders of commentators as the Really Smart Guy Who Called The Correction In Advance. nevermind the 10,237,134 false predictions before it

You can use both of them in that scenario, and also the underlying itself. Things you can do much more easily with options is create a strategy that more closely defines what your position is. I don't really get, and maybe someone can explain, how you could use futures for things like downside...

Spend the money with iqfeed. It will cost you $500 all in, and maybe a couple a hundred a year after that.

I've heard they're taking the draconian step of requiring a heartbeat and breathing to get a loan.
