How does Valuation lines indicator works in zerodha kite? I dont see any documentation on that

I see the indicator Valuation lines in zerodha kite, but no documentation is provided for that. I want to know how it works and the implementation part of it. Can anyone guide on this or provide any links or documents for this?
@nithin

That is straight forward, it just displays averages like mean and median and standard deviation of selected data.

@siva yes but every time we zoom in or out, it changes. So any ideal condition or TF that we should use it in?

The more data is added , it consider all that and then gives out output for that, there is nothing as default or ideal as it is user specific.

Then how do I decide which SD level is the stock trading at?

It’s upto you to select timeframe, if you want to see daily 1sd, open daily timeframe, zoom in such that 1 year data is there and see stocks SD levels.

Right. thank you
