Sorry,
I still don't get it. yesterdays volume times 0 = 0 yes? so.... v+0 equals
today's volume.......

Twiggs Money Flow formulaHi JaysonI write to Colin
Twiggs for clarification of V+(Ref(V,-1)*0) Here is his response:The
first day of TRH is calculated on day #2:TRH:=Max(Ref(C,-1),H);The
purpose of +(Ref(V,-1)*0) is to bring volume into line with the above; so
that the first day of volume used is day #2, and not day #1, in the last
line of the
calcuation:If(WV=0,0,Wilders(ADV,periods)/Wilders(WV,periods))CheersAnthony---
