Average True Range - J Welles Wilder

The calculation of the Average True Range - J Welles Wilder is similar to the Average True Range indicator's in that both first measure the difference between the High and Low price of the interval (the range) and then use that True Range value in their subsequent calculations.

The Average True Range calculation ascertains the "true" range for a number of intervals and then averages those true range values.

The ATR-JWW does not average all of the previous intervals' TRs, but rather gives more weight to the most recent ATR-JWW value and only averages it with the current interval's TR result.


The resulting ATR-JWW graph gives proportionately much greater weight to more recent results and consequently has a smoother appearance.
