That said, after doing this for years, I have yet to strike the mother lode.;-)
I have written algorithms for every trading strategy and indicator known to man...and have yet to find one which can effectively predict significant stock movements over time.
I have even written algorithms which combine two or more strategies. Lots of nerd fun, but still nothing reliable.
From what I hear, the quants at successful hedge funds use information from data mining companies. For example I recently heard of a firm that was buying satellite streams so that they could examine freight truck movement from factory parking lots.
Now that’s cool.
If I were doing that, I would zero in on the truck traffic from a company that I visit that makes the rubberlike pads used to print boxes and containers.
