What do you find so aesthetically pleasing about it? Is it the mathematics/model building. Portfolio allocation mean-covariance? Different hedging schemes? Black-Scholes model? Different numerical methods? Is it the system design? Use of FP to model different contracts or concurrency and distributed trading systems? Or is it the statistics and back-testing? Personally, I like the aesthetics a bit but mostly I love the thrill of gambling and watching the market tick and the aesthetics of CNBC money-honey's.
