Fidelity shows no price either, but I've had a couple small sells go through so I think it's fine - guessing we won't see a price until tomorrow though. It does show a bid & ask when I click on Get Quote.
The best you can do is call Schwab. I have TD Ameritrade and for the first few hours it didn't show my position. Then it changed over to DPWWD with the reduced shares. Once it changes to DPWWD you can trade it. Eventually when everything is finalized the ticker will change back to DPWW. I've been through reverse splits before so I know the process. It may take some trading platforms longer than others and they likely will charge you a reorganization fee. Call them on it and don't let them (your broker) pull that crap.
