Do me a favor, draw on this image I am posting below what it is you want to do in the above...

2 seperate versions / time-frame implementations of Time-Segmented Volume turned into a copy of the 3C indicator used by trade-guild.net or at least my versions. They encompass the two crazy lines are I use them as leading indicators of institutional money flows. Then, I have TD Propulsion and TD Setup for trend as well as TD Price Flips. Yes, I do use them all and sometimes even more and quite well too

declare upper;
input n = 2.0;
input p = open;
input offset = 1;
input average = yes;

plot zig = reference zigZagpercent("reversal amount" = n, "price" = p);
zig.EnableApproximation();
def sign = reference zigZagtrendpercent("reversal amount" = n, "price" = p);
def new = if !IsNaN(zig) then 1 else 0;
rec count = if new then 1 else count[1] + 1;
rec vol = if new then volume else vol[1] + volume;
def avgvol = if average then roundDown(vol[1] / count[1], 0) else vol[1];
def up = if new and sign > 0 then 1 else 0;
def down = if new and sign < 0 then 1 else 0;
AddChartBubble(up, high + offset, concat(avgvol, ""), color.blue, yes);
AddChartBubble(down, low - offset, concat(avgvol, ""), color.black, no);
