Yeah, no worries @Vonasi. By “bust” I meant “not possible/doable” which you’ve commented on. 

I had this idea — despite the fact that it’s very time consuming to make the indicator overlay onto the price chart and the limitations of accounting for Fat Tailed events in a PDF, as alluded above with the 64 year S&P 500 study —  that it would be great to see your indicator with those 1, 2 and 3 std deviations drawn in as straight lines within the distribution (curve) (and as a separate indicator below the price) to show the probability of where the price is settling. So like my blue bell curve image with the 1, 2 and 3 std devs at the top of the previous page but with std devs now marked out within your distribution:

I note that actually there is a lot of Skewness.

It’s useful not just for options trading and understanding the probability of options going ITM or OTM but also just for general trading and price predictions estimates. I did find this link below though which is why I thought I’d seen this type of indicator on PRC and not elsewhere!

A coder on Trading View has gone into detail about Std Deviations and Probability Cones for anyone interested:
