Thanks to HST plunging today by ~75%, I see for the first time ever, a 6-sigma event in pairs trading.
Apparently the confidence interval of 6 standard deviations is 99.9999998027%.
My signals calculate standard deviations based on 14 days standard deviations. A 6 sigma event should only be experienced once every 19 million years... crazy stuff.
