That would be more bad news. From what I understand TDA should be one of very few brokers without issues. Except they don't accept customers from Europe.
I bought through TDA, but if they(friends) just deposited their fund it may take a few days to settle through their clearinghouse.I hope this is the case for them?
I have Vanguard and TDA. Previously on Vanguard I was able to buy non-reporting OTC stocks. I'm no longer able to buy. I haven't tried selling yet. As for TDA there hasn't been a problem.
