I tried to beat the market using all kinds of AI stuff off and on for a number of years. Learned a lot about AI techniques, and became a better programmer, which helped in my day job, but never got anywhere. It's a fool's game. Besides, most of these HFT systems hold positions for only a few minutes or less. There's no way someone without a huge account, to cover commissions from trading so much, and access to a lot of expensive real-time data streams could possibly make any headway at it. Not to say there aren't people who do make money at trading, but they are swing traders and/or people who've figured something out about the market that the market doesn't know yet, and thus has not revealed at all in the price movements of the stock. Since price movements are the primary input into a lot of trading algorithms, most trading algorithms are blind to these developments.
