Once you have linked to a MCA, you can log in to DBS/POSB iBanking, select Invest > DBS Vickers Online Trading. Under “My Account” tab > select “Account Management” > select “Switch your Existing Settlement Account”. Note: A switch can only take place if there are no outstanding contracts/payment in your current-linked MCA account.
