Can you also elaborate on what drives the auto coloring of the indicator?

Hi

Why the value of Volatility Trend is not coming as 1 or -1 as per the color of the graph red or green.

Spreadsheet values are showing an average price value as below;

[ID7] Volatility Trend Indicator
[ID7.SG1] Volatility Trend  [ID7.SG5] Dynamic Period Length
3895.883056640625  26
3906  25
3875.506591796875  24
3884.422119140625  23

The price information is the correct result for the Volatility Trend Indicator. This is reflected in the documentation for this study. The values of 1 or -1 are just the directional values of the study and as you state, are reflected in the coloring.

You will find the documentation for this study here:
https://www.sierrachart.com/index.php?page=doc/StudiesReference.php&ID=155#Volatility_Trend_Indicator

If the Directional information is something you want to use, you can modify the study, as the code is available in the file studies.cpp.
