LR from Prev close

This is my simple indicator to help identify whether a downside bar is unusual or not. I like to see a bar as particularly unusual like a 15% move in a long period where a typical move is under 5%. It usually signals a selling climax and the end of that short term selloff.

I compares the previous bar's close to the current bar's low and is expressed as a percentage.

I am not much of an expert in pine so I did not program it to plot as a histogram but that is how I like to view it. If you know how, by all means, send me the edit and I will credit you.
