tom_b, basically every shop cooks their own solution for just about everything. if you do mid- to low-frequency a Bloomberg will suffice. if you do high-frequency you are in the infrastructure game. you co-locate to the exchanges and battle for the milli- to microseconds. there are a few specialized databases in this area for dealing with TBs or rows.
everything else in the area of finance is a complete waste of time IMO. basically the financial system is toast. I hope that bitcoin will improve some of the absurd structures we have set up.
anyway, if you want to know some specifically you can go to nuclearphynance. There are some cracks around there. good traders would consider an MFE as the opposite of helpful, I'm sure. standard stochastic calculus is pretty much useless.
There are fully managed solutions to receiving market data etc, that a lot of companies do use, both in the enterprise, and HFT realms (ie tickerplants).
Yeah, for 100k$ or more a year. So you need a lot of capital to get started on your won. Getting started with a private account is hard to impossible in my experience. Lime Brokerage offers good stuff for HFT. You need about 12 months to get really going.
What is the difference between strategies used in mid/low frequency vs high-frequency?
I understand high-frequency is mostly stat arb but I haven't heard of too many quant funds that do mid/low frequency. I've seen one present before that used small changes in portfolio optimization to get an alpha of ~0.2% over the benchmark but that didn't seem too useful.
