HKEX:HSI1!   Hang Seng Index Futures
Looks to me like this is going to be the determining factor for Tuesday open....

Hang Seng is oversold, I would expect it to bounce off support Sunday and Monday, which would mean a gap up Tuesday morning.

Of course, the virus thing is unpredictable and if China shuts everything down again we could see a double bottom. Not to mention they're trying to clamp down on Hong Kong which usually tanks the Hang Seng (it's the Hong Kong index after all), so there is the possibility that it goes severely oversold.
