Volume quantity in the last 10 seconds script label?

[drive9]

I code by copy/paste and frankesteining my needs. Can someone help me here, I'm trying to get a label that tells me the amount of volume in the last 10 seconds. This will give me an idea of the intensity of the tape in a very short span for entries/exits. All ideas are welcomed

input VolStatsPeriod = AggregationPeriod.MIN;
def HO = open(period = VolStatsPeriod);
def HH = high(period = VolStatsPeriod);
def HC = close(period = VolStatsPeriod);
def HL = low(period = VolStatsPeriod);
def HV = volume(period = VolStatsPeriod);
def HBuying = HV * (HC - HL) / (HH - HL);
def HSelling = HV * (HH - HC) / (HH - HL);
def  HtotVol = Round(HBuying, 0) + Round(HSelling, 0) ;
def htotvoltensec = round(htotvol - htotvol[.16],0);
addlabel(yes,"volmin: "+htotvoltensec,color.gray);

I know the volume - volume[1] will give me the volume in the last minute, however, the downfall is a big order can skew it for a whole minute. I still havent figured it out and help is appreciated.
.i.e. xxx.x[Xx.]x.x.x.x.x.x.[XX.x.x.x.x.x.x.x.xx.x.x.x.x..x.x].x.x.x..x.x

To the best of my knowledge, this can not be done. The current iteration can only be accessed exactly as it appears at any given moment, and prior iterations can only be accessed in their final state. Time related functions only recognize the exact millisecond that an aggregate begins. You might be able to accomplish something at least somewhat similar by using a small count tick chart, but that's really up to you to figure out. No guarantees, that just where I might look next I were you.
