DAS Montage - Lv2 Dynamic Scale Bars

[Hamish Arnold 1]

I recently activated the Lv2 Dynamic Scale Bars in the Montage of my DAS. This is very helpful in gauging the relative levels of bid and ask volumes, however under the colour coding of the various price levels there is a second bar (defaulting to red/blue/grey bars) which seems to reduce over a period of time until the order information resets.  Example is shown below:

 

Does anyone know what these reducing bars, or their colours, mean?

Thanks all, as ever!

Have you gotten an answer for this? I'm researching this now.

Jeremy,

No.  I have no thoughts answering this one.  Any pearls of wisdom would be keenly appreciated!

The Dynamic Scale bar  is the changes of the first item in level 2, so the first line changes, it will re-count it, 10 seconds. And the color is base on the upticker and downticker,  up is blue and down is red
