Hi,

I would like to run a test on MNQ with 20-25-30-40-50-60-75-90 second bar periods and see the summarized performance results for all bar periods. Can this be achieved in Zorro somehow?

Yes. Run Test mode with different bar periods and save the results somewhere. If you want to automate it further, try batch scripting. (A perfect example can be found in the Trend Experiment blog series by the Financial Hacker.)

Thanks for info Andrew! I thought I have to save the results of each test in separate csv then merge them and use zorro to read back and analyze the data.

You also have the option to use a fixed bar period (5) and optimize to an array of fixed time frames instead (4,5,6,8...)
