Hello,

I was wondering if there is a way to have more parameters for Z1/Z2 strategies (like exclude particular pairs or cfd)

I believe you can do this by editing the optimalf setting in one of the files to 0 for the pairs you don't want to trade. Have a look towards the start of the threads and it is explained.

1 - According to the tests that have been done, what are the best parameters to run z1 and z2?

I understand it are:
Margin = 50
Risk = 10

Thus for both scripts?

2 - How do I run z1 and z2 simultaneously on the same account? I need 2 PCs or 2 VPSs? In this case the parameters change with respect to the previous point?

Thanks.

Both Margin and Risk affect the profit and the required capital. So just click [Test] with different settings until you end up with the capital you want to invest. It will be different for Z1 and Z2.

You can normally run two Zorros simultaneously on the same PC. According to FXCM this won't work, but we found that it works when Zorro logs out every weekend, which it does with Z1 and Z2.

jcl Im actually running 3 instances at the moment with 3 different strategies testing, seems to bug when I try to trade a 4th instance though.

You can normally test as many instances as your PC's memory allows. What do you mean with "seems to bug"?
