You may close any Account/Fund you have opened in PAMM. So as to be able to do it there should not be any active funds within the account.
Follow the steps below for further information on how to close a Fund or an Account:
On your Hive Markets account, click on My Accounts.
Select the Account or the Fund you want to close. To view all the funds, click on the arrow next to the Money Manager account and then select the view button on the right side.
Tap on the 3 dots next to the Account/Fund Number and select the Close Account option.
You will need to confirm the closure in a message that will show up on the screen. Click on Yes if you would like to proceed.
