- Trading strategies that are tweaked to past price data must indeed be tested with a different data set for making sure that they also work with real trading. This is a nontrivial problem. Zorro uses an approach called Walk Forward Optimization - you can find details under "Training" and "optimize".

- The current minimum capital for the Z1 and Z2 strategies is $4000, but we hope to get this down to about $2000. When you test it with $100, your chance to lose them is almost 100 percent. Zorro calculates a minimum capital for every script, and that capital is really required. When you just want to test, you can do that with a demo account.
