The NHNL indicator in GTR1 uses the 9d Weighted Moving Average. If the 9d Weighted Moving Average is > 0, the indicator is bullish.

Stockcharts does not include weighted moving average as an indicator. Exponential moving average is close, but not identical. Barcharts includes both. You can see the difference here:

As of today WMA and EMA are both slightly negative.

The issue of replicability of NHNL is not simply how the moving average is calculated, however. It also has to do with how New Highs and New Lows are counted. As I say, this came in for discussion on the old board, and can probably be found by searching. In the end, however, there is no getting away from the fact that GTR1's way of counting new highs and new lows is not replicated by readily available public charting or data services. This is a matter in which small variances are common. Stockcharts and Barcharts do not agree precisely either. From my perspective such small differences do not matter; a matter of opinion and use, obviously.
