From NYSE website, "GMMVF"-> "GMVD" was CLOSED on trading on 10/21/2020 08:45:18 and has NOT been traded since. (which also match the last trading data shown in the TradingView.com: US$0.2788 with volume of 283.)

How to Track Upcoming Initial Public Offerings (IPOs)

(both actually show all new IPOs at both Stock Exchanges not just showing IPOs boarding at its targeted SE)
Personally i like NYSE website better as it also includes "Withdrawn Deals" section in the end and also not many Ads embedded in the information page.
