Is there an easy tool where I have a chart, and then I can put a price level, e.g. here "$2.18" and then this tool calculates the percentage of time we spent below that price level, kinda like probabilities?

I mean you can totally calculate the number you were looking for in your original question! But if your reason for calculating that number was to use it to inform your trading then yeah that’s not a great use of your time.

why? Because the stock market priced aren‘t uniformly distributed?

Yeah it’s not following any kind of distribution where you can argue that it’s going to “revert to the mean” or anything like that.
