It is impossible to have that problem with the latest version of the plugin, since MaxDaysToReturn is never set.

I don't know why you are linking to the old version, the new one is much better!

The documentation has completely changed, too. Read:

Also, I have no plans on supporting that method of access. Use AssetHistory:
https://manual.zorro-project.com/loadhistory.htm

I might eventually put in a separate brokerCommand if I have time to spare.
(Or I can expedite it with a sponsorship.)
