Value Charts — Another Way to Trade the Markets
Creating Value Charts in TradingView
Value does not have to be exclusive to fundamental analysis. We can also, create a value chart in technical analysis which acts as a reversal indicator.
Creating the Value Charts
Value charts were first introduced by Mark Helweg and David Stendahl in their 2002 book — Dynamic Trading Indicator. The main idea was to enhance the relative strength which has many limitations due to the fact that it is unbounded.
We typically use them in a different panel and treat them as indicators. We need two concepts to create the value chart:
Then, we calculate the extreme range which is the difference between the high and low of every time step. Next, we need to calculate the volatility unit which is simply a 5-period moving average of the last calculation multiplied by 1 / the selected period, in this case, it is 5.

Finally, we use the below formula for the OHLC data to create the value chart.

We generally watch for subjective barriers for reversal moves.
Using the Value Charts
Value charts are used the same way as other contrarian indicators such as the RSI even though the name of barriers differ as with value charts, we tend to say overvalued/undervalued and with other indicators, we tend to say oversold/overbought.
You can also draw trend lines on the value chart like the following:
