This is the acceleration of a chart written in pine. It's the second derivative otherwise the derivative of the momentum.
It shows how fast a stock's momentum is changing and in what direction.
As standard I left the controls in the settings for source and length of the estimate.
I will be incorporating this in other more complicated scripts here shortly
Different version of the CM one but everything is configurable and easy to manage.
Daylight savings may also be toggled, I cannot automatically toggle it yet but hopefully with a pine update I will be able to.
It had the four main sessions but version two could possibly have all of them as optional toggles
Hope it is useful
