Does the indicator "Footprint Chart for NT8" work with real bid/ask volume (like the gomi indicators used to on NT7) or do these work with tick data? If so, does anybody have experience wrt. comparing tick volume vs "real" volume? Can I rely on this tick-based Footprint?

I have made some research (installed Ninja 7 alongside) and it seems that the NT8 version uses real bid/ask volume just like the gomi indicators.
