[quotes-plus] Filter Question

[burlap58]

I'm new to QP. I don't understand one of the filter columns. The
column % vol/50 DMA vol has negative percents. Wouldn't that mean
there was negative vol for the previous day? I would like to know what
percent yestrerdays last volume is to the 65 DMA vol, but I can't
understand how that could have a negative value? And is there a way to
edit that to a 65 DMA? Thanks, Lloyd
