First day of any significant volume yesterday, though it can't be traded with Schwab as of yet. Have not really done any research, I usually wait to see if I can get someone at the Trade Resolution Desk to add it to the ThinkorSwim database first, its kind of hit and miss, sometimes they add them for me, sometimes they don't. TDA was much better about adding new symbols and CUSIPs. I don't like to waste my time researching something I can't trade.
