Hi,

Is there a way to clear RAM at the end of the test? I have 32GB RAM and the second time I run the test it shows the memory fragmented or unavailable error message. 70% of my ram is free and Zorro still gives that message. Hope there is a workaround because it's a little bit uncomfortable to close and open Zorro after each tests.

If you need to run many known tests, you can batch script them.

Can I change asset and timeframe with batch script?

Absolutely. You can even change BarPeriod, since each Zorro instance it is its own process and has its own memory allocations.

Looks like I have to learn batch scripting.
Is there any howto or documentation for controlling Zorro with batch script?

There are many approaches.

Windows batch files (generic):

You can even write your batch file in Python, or even a Zorro script.

You'll definitely need to know how the Zorro command line works:

But the best example I've ever seen of batch scripting can be seen in the Trend Experiment on the Financial Hacker blog (download from "Scripts 2015" in the sidebar):

Thank you Andrew! It works flawlessly! Have a nice day!
