I can run one demo instance of zorro with the fxcm plugin and one with the mt4 bridge on the same pc or vps. So this is a max of 2 strategies being tested per PC or vps without zorro S.

The solution is zorro s or multiple vps, this is simply a cost issue. I'll have no problem committing to zorro s and a robust vps solution when I have successfully tested the strategies either z strategies or my own.

I'd never run a live robot on real money on a home pc, I trust neither my electricity supply, my broadband provider or my fellow dwellers not to mess it up.

Testing is a bit of a nightmare though, as I've limited scope to test the z strategies and my own.

I think I know the answer to this one, but I'll ask anyway, jcl why can't there be a zorro version that is limited to demo accounts only but allows multiple Demo instances to test multiple strategies on a single pc or vps?
