The script is correct. Maybe you clicked the wrong button? Click "Test", not "Train" or "Trade".

I tested this script too but nothing happened.
Yes, I clicked the test button.
Let me know if there are other methods to update the history.

I think the method is not the problem. Can you post the output of the script so that I can see what problem you have?

It is only complied. Nothing except it.
I could download price only one time.

If it worked one time, then check what you did differently this time. For instance, entering a wrong user ID and password to the broker login.

When the prices are already up to date, no new price data is downloaded of course.

Zorro keep saying "Delete old logs" each time I click the test button unless I click yes.

Please correct it. I just want to save the old logs.

if you don't want your workflow interrupted looks like your only choice is to move old files to a different dir
