I have no idea, I keep getting the 'rejected: this security is currently unavailable'. message, this is not the typical message for a DTC chill restriction, that would be 'opening transactions are not allowed'.....so I really don't know what the issue is....and TDA is of no help....lol.
I had to give up on tracking 'F' tickers as well, as TDA just wont add those to the TOS database, they added a couple non-foreign securities for me, but wont do the foreign ones, and wont elaborate why. I gave them a huge list they did not have, maybe it was too much work....lol.
