It's just not how markets have historically functioned; a strike on June 21st can't change the fact that nothing happened on June 19th or 20th. The record shows that if there were no strikes on those specific days, the market resolves as 'No' based on that period. Thinking otherwise is like saying a new law passed today changes what was legal last week — it's not how precedent works. For instance, if you bet on rain Tuesday and it rained Wednesday, your Tuesday bet still loses.
