Believing a market's resolution is a fixed, final thing is a waste of attention and a drain on your liquidity. Just because nothing happened on June 19th or 20th doesn't mean future news, like military strikes on the 21st, can't change how everyone values those earlier dates. Think of how often a company's stock price on Monday can jump or tank based on a Wednesday announcement; the past doesn't stay neatly resolved when new information hits the scene.
