Sun. Let me get this clear. You transfer $$$$$ from your chequing account to your brokerage account. This money is as good as gold but takes 3 days to get into your brokerage account. But, You transfer from your yield (debit) account to your brokerage account & the $$$$ is there in minutes ? I googled yield (debit) accounts & it says they are chequing accts. Thus my post.
