GenetiTrade is free software for maximizing the trades in a math trade. It is a Python program, so it runs on any system on which you can install Python (UNIX, Linux, Windows, etc.). What really distinguishes GenetiTrade from other similar programs is that is based on a genetic algorithm, and evolves its result sets. One of the easily observable effects of this is that it rarely produces the same output twice (unless there is somehow a very finite set of possible results, of course). Also, in multiple runs over a fixed timespan, you may get very different numbers of trades.
