I would like to request for the NBBO lines in the graph/chart to be in different color or different shade than the Best Bid/Ask lines so that I know which one is which without hovering my mouse over it to identify the lines. The NBBO lines should have a different shade of color with high contrast with the Best bid/ask lines so it's easier to identify visually. I think it's important specially in highly volatile stocks. This would help us study the behavior of NBBO level in relation to Best Bid/Ask at different situations as there isn't that many information out there about it.

Thank you,
Adrian
