An investor is free to exit a fund they have invested in at any point.
To exit a PAMM Fund you can follow the steps found below:
Go to the Investor's widget and select the relevant fund.
Click on the three dots and select Close Account.
When you are ready to proceed, click/tap on Close Account.
Once you have exited the fund, the money invested will return to your Investor account and you will no longer earn any profits or incur losses from that fund.
