Hi Dave,
I was referring to this indicator: Choppy Market Warning
You should be using Izone Sharp Shooter Templates for spreads and use CONTINUUM not shadow bars and the trend chop bar colors the bars.
https://www.youtube.com/watch?v=HA-c7_y3Nhw For futures this will work with a futures only feed like CQG/ Continuum or IQ Feed.
Here is the full training on IZONE Sharpshooter for spreads: https://forum.apexinvesting.com/t/izone-sharpshooter-set-up-and-rules/4415
Part of the confusion is your asking about forex then asking about index futures which is it ?
