I had posted the idea with the preceding peak, but then realized that it's a bad idea. The same max drawdown would then get a different percentage dependent on when in the simulation it happend. So, this won't work.

I understand that there are 100 different performance metrics, but we want to concentrate on the useful and relevant ones. You can easily calculate your favorite DD variant in the simulation and then print them to the performance report. Further suggestions are welcome - please post them to the Zorro future forum.
