I downloaded and started to fool around with another genetic algorithm addin for Excel. This one is called xlbit and is created by Xlpert. What I like about it is that it has a better interface than Gentik Solver, but its not free. It allows you do max and min for target cells, add constraints (a big plus), and lets you choose between three genetic algorithms: Elitism, Roulette, and Tournament. It even creates a new worksheet with results and graph for your average and overall fitness. Sweet!
If you like it, and I do, you can buy the addin for $15. That's pretty reasonable considering the developer packages this addin with two more addins, a neural net and a type of value at risk routine. Xlbit does come in a demo version, so you can try it out first.
So what has your intrepid neural net / genetic algo techno trader been doing with this addin? Writing new trading models? Analyzing the market? Finding hidden trading opportunities? No, not at all. I've been genetic modeling the perfect measurements of women.
