Not everything has to be super fast. I was using quantopian to trade based mostly off fundamentals data on a monthly rebalance basis successfully. At least enough to beat the sp500 for a few years- I stopped because I went to a hedge fund that prevented me from trading that frequently and in most small caps. If you want an idea take a look at the piotroski f score and factor based investing. Aqr for example is still largely factor based.
