Hi Brock,

I was looking for a indicator called Volume BreakDown, you can see at

I could not find it, so I tried to develop that indicator, however; I have some difficulties, I woundering if you could help me, the indicator that I developed is below…..thank you
The problems are:

1. the totals (TotAskVol and TotBidVol) are always set to 1 when new tick occours;
2. the chart level is changing all the time;

thank you,

SetChartOptions( 0, chartShowArrows|chartShowDates );

_SECTION_BEGIN("Bahia Vol Breakdown 3");


   /*  variables iniciation    */
   Last = GetRTData("Last");              /*  last trade price    */
   Bid = Ref(GetRTData("Bid"),-1);        /*  last Bid    */  
   BidVol = Ref(GetRTData("BidSize"),-1); /*  last Bid size    */
   Ask = Ref(GetRTData("Ask"),-1);         /*  last Ask    */     
   AskVol = Ref(GetRTData("AskSize"),-1);  /*  last Ask size    */    

   first_time_empty = MA(Last,3);
   onetime = IIf(IsEmpty(first_time_empty),1,-1);
   TotAskVol = IIf(IsEmpty(first_time_empty),1,-1);
   TotBidVol = IIf(IsEmpty(first_time_empty),1,-1);

if ( onetime[BarCount - 1 ] == 1)

   /*   variables iniciation    */
   Bid =0;

if (Last[BarCount-1] == Bid[BarCount-1])

   TotBidVol= TotBidVol + BidVol;


   TotAskVol= TotAskVol + AskVol;

Plot(-TotBidVol,"Bid Vol",colorRed,styleHistogram|styleThick);
Plot(TotAskVol,"Ask Vol",colorGreen,styleHistogram|styleThick);
