In order to withdraw funds, you will first need to sell out of the amount that you would like to withdraw from your portfolio mix. You can do this by logging into your Swell account and selecting the "Sell" option from the "Manage Mix" dropdown on the navigation bar.
Once the trades have settled (which takes approximately 3 business days), the cash will be available for withdrawal. You can withdraw this balance by logging in to your account and selecting "Withdraw" from the "Manage Mix" dropdown on the navigation bar.
All-in-all the process can take between 5-7 business days.
