Anyone have any experience selling 0DTE options on SPX / SPY on the day after thanksgiving (tomorrow) given that it’s a half day? The theta crush will be accelerated as is the gamma tail risk but trying to understand what else to be aware of, is it a good idea or will you be sitting out tomorrow, etc? Any insight would be very much appreciated. Thanks in advance!
