The feature which I believe will be very beneficial would be the ability to transfer cash funds between your Trading212 accounts. For example, the ability to simply move uninvested cash from your ‘Invest’ account to your ‘ISA’. This is would completely remove the wait period of withdrawing cash into a bank account, simply to redeposit into the same entity, but different account. I believe this is something quite easy that which Trading212 could implement, and would be a very useful feature most of all.
Already possible. Top right menu > Manage Funds. Then a dialog opens where you can move funds from one to another.
