Hi,
Is there a way to manage Streak baskets (delete and rename backets, add, remove stocks), etc?
You can not make changes to the premade baskets that are made available.
However, you can create your own baskets(Technical lists) and delete and rename them, and add or remove stocks from them. Refer to the below link to learn how the Baskets(technical lists are created)-

To explore and learn more about the Streak baskets (like Adding a basket in the scanner, Adding a basket in strategy, Importing or Exporting a basket ) simply scroll down on the same page.
