I think you can't trade it at all within 3 days of the split. Your brokerage will advise. My brokerage still shows last week's share count. The reverse split means ALL 6B shares are recalled, their numbers are retired, and new ones are created with new numbers and sent to the brokerages, etc. The 'D' should last 30 days until it reverts to SPZI or JP3E. Right now it is SPZID.
SPZID is the new Symbol for the next 20 days. I use Ameritrade/Charles Schwab and it works just fine. All my shares were transferred around 1 o'clock today. I can buy Or sell just fine on their platform today.
