I guess you want to create some custom report? Because all the metrics you mention are already in the default performance report.

If so, strategy parameters can be found here:

Using the for(all_trades) construct (http://zorro-trader.com/manual/en/fortrades.htm) and the Trade parameters (http://zorro-trader.com/manual/en/winloss.htm) you can calculate pretty much any other metric you want.
