While optimizing in the system tester is a great feature, it is limiting to only have max profit as the goal of optimization - a smooth growth in equity is preferrable to running a jagged up and down gauntlet. Currently, one can only increase the number of results and look at the equity profile of each, but this isn't feasible for large numbers of tests. This is a real gap in an otherwise powerful system for testing.
While adding optimization options could get pretty complicated, with multiple goals and the potential to rank them by preference, simply adding one option - lowest standard deviation of returns - as an alternative to max profit would be a great improvement, indeed
