Yup..I've been researching this field for a while now. At first as a curiosity after the "flash crash" when news reporters were saying it was caused by a trader who accidentally sold a billion shares, when he meant to sell a million, which triggered panic... That made no fucking sense to me... Later, stories developed about black box trading and its role in the flash crash, and in our current economic crises. Most of my recent research on the subject has been as a potential career path after i get my phd, and research subject matter.
There are some great books on the subject..One is called The Quants by scott patterson. "Quants" are the term for the people on wall street who engage in quantitative methoRAB for trading. Market models, purchase algorithms, etc.. They make upwarRAB of 30-40 million/year. Some of the fastest supercomputers on the planet are owned by hedge funRAB and wall street firms, to compute these models and execute trades..
Very interesting stuff..
