I thought the TDAmeritrade policy was that ACH transfers require up to days to buy an OTC, so I was using costly wire transfers. However, MY LAST TWO ACH TRANSFERS USING THE TDA DEPOSIT PAGE RESULTED IN BEING ABLE TO BUY CYDY, IMMEDIATELY. Here is the policy for ACH transfers initiated through TDA:
When will my deposit post to my account?
We immediately credit your account for deposits made before the cutoff time. You can then trade most securities.
When will my deposit clear?
A deposit may take up to four business days to clear after it posts to your account.
What restrictions exist?
Until your deposit clears, we restrict withdrawals and trading of some securities based on market risk. This includes but isn't limited to options and most stocks priced under $5 per share.
