standard deviation charts

Hi @tatj@att.net , I don't know if this is what you are looking for, but SC has a Slope indicator that takes a parameter of your choice. Here's a link to the Chart School article that explains what it is/ how it works:

Although it's an indicator you would normally put under or above a chart, you can choose to put it "Behind Price", which puts the Slope line on the chart.
