Agree, Schwab is always the 1st to find out about these types of things and they notmally allow trading in everything.
What is really odd today is that I have had 4 PRPM buy orders stuck in that blind cusip to ticker spot. I could not cancel the orders because it told me that they didn't exist (haha, they were there but Schwab cannot identify the ticker now). This morning a mil of my .0008's on the bid traded. Now I have 3 mil more .0007's on the bid. I cannot cancel them. Who knows. Strange
