Hi rooster, the chart you are looking at is the "cumulative volume" chart or "wave chart". This looks at the effort used for each up or down move it is good for measuring reward for effort along with increasing demand and supply etc etc.

Allday, the pink volume bars you refer to is lower volume than the two previous days/bars, with the blue volume lines higher volume than the two before it etc etc.
The arrows simply point out potential bars of interest and is all part of the platforms workings.
While I like the easy to define volume bars, the red and green arrows are left wanting IMO, and commonly miss important bars of interest and even miss interpret them.. In fact the platform in general is left wanting IMO.
Much better off learning the basics and forgetting about the arrows.
I don't use them anymore...
