Don't know the answer to this even though I primarily trade SPX. If you are able to sell puts expiring today that are down 30% and the market closes if we are down 20%, you would think it is a safe trade. I realize there may be margin or clearing firm issues, but you would think its a safe trade.
I don't plan on doing this but curious what others think.
