Yeah I was researching this after market closed and using look back for option prices 2 days ago so not most reliable but the spreads were wide and if you buy at the ask or even inside the ask/mid point. You would need a huge move to overcome the spread to get out and you could be marked already down 40%. I think a filter needs to weed out illiquid spreads to add a little reality to this.
The software has that filter and warning.
