Hi Ibra,

You can only adjust margin, with Zorro S. Otherwise you need to use the pre-defined capital requirements and margin requirements built into each system...at least I believe that is how it works. Someone correct me if I'm wrong.

If you have Zorro S, when you open zorro and start up your strategy, there will be a margin slider, where you can adjust the average margin per trade. Optimal F will then kick in to adjust the margin on individual trades, based on the training.

Trust this helps. All this is in the manual too.
