Volume Indicator in Omega Chart = Up Volume and not Total Volume ?

["Jean-Luc Schmidt" <jl.schmidt@xxxxxxxxxxxxxx>]

Hi OmegaList,

Could someone explain me why does the Volume Indicator for chart in minutes
return the value of "Up Volume" and not "Total Volume" ?  It doesn't seem
correct. How could I change this ?
( in days charts, I get Total Volume)

thanks for your answer
