CME will open in an hour... will be interesting to see what happens; must suck to sit on a short and not being able to get out over the weekend 
Does somebody know how the price limit works? I mean halting BTC futures trading will not get BTC price changing.
Will the be forced settlements?

not sure what you mean with how "the limit works"
when futures trading opens there will be i think gap up, instant gap up
so if shorters had close limit on 10500 and gap up instantly put price to 11000, they will close with 11000 and not with 10500...at least i think so
Good question.
Can they sell if the limit is hit? This would mean that the longs are forcefully pushed out of the contract?
Could be setting up for some major carnage at the CME that's for sure. ... bulls have got it back to the AYH right before the open too so it might spark a massive surge up on the short squeeze at the open.
When CME went live with the contract in Dec. 2017 I recall an ex-CME head or regulator warning that CME had never dealt with a truly hard asset like bitcoin and it was a real risk for it to cause major failures ... which is a joke because he was admitting that gold was not a hard asset in the way it has been papered out of existence.
Edit: meant to add that there will be a battle to get it back closer to friday's close before the open to stem the bleeding.
