Constant Valuation Multiple Levels

This indicator adds price levels at constant multiples based on your preferred valuation metric. The settings provides options for setting this metric while Operational Income is the default one.

This indicator is not perfect as it relies on historical earnings data but does not have forecast data (not available in pinescript), thus its not a guide for future price level. It also does not account for "adjusted" earnings which may skew levels for some quarters.

However this script provides a quick way to see the stock price against your preferred valuation multiple to see if it's undervalued and worth investigating further for quality and earnings forecast.
