Would anyone please take a look at this code, this code seems to work properly on historical data but not in real time. This is relative volume indicator works on min chart only.

@ABCTG any help?

 

Code

// __RACumVol - Average Cumulative Volume at this time for the last X days. // Must be used on minute-type intraday charts Inputs: DaysToAvg(14); Variables: BarInDay(0), BarsToday(0), CumVolToday(0), DayNumber(-99), BarsPerDay(26), TotCumVol(0), AvgCumVol(0), VolPercentile(0); // Declare the array. Rows = number of days to average; columns = number of bars per day. // Add one to rows to avoid using row 0. IF BarType = 1 then BEGIN value1 = TimeToMinutes(SessionEndTime(0,1)) - TimeToMinutes(SessionStartTime(0,1)); value1 = value1/BarInterval; If FracPortion(value1) = 0 then BarsPerDay = value1 else BarsPerDay = value1 + 1 - FracPortion(value1); //Arrays: VolArray[22,405] (0); // Note max bars of 405 ( 1 minute 9:30 - 16:15 ) Arrays: VolArray[22,495] (0); // Note max bars of 495 ( 1 minute 8:00 - 16:15 ) If Date<>Date[1] THEN BEGIN //If we've passed day 20, then move everybody back a seat. // All of day 2's data in the array goes into day 1, day 3 into day 2, etc, up through 21 into day 20. IF DayNumber+1 > DaysToAvg +1 THEN BEGIN For Value1=1 to DaysToAvg Begin; {Outer loop - one for each day, 1-20 + current day } For Value2 = 1 to BarsPerDay Begin; {Inner Loop - one for each bar in a day, 1-26} VolArray[Value1,Value2] = Volarray[Value1+1 ,Value2]; End; End; END; // Start/Increment Day Counter. It never goes above 21. IF Daynumber = -99 THEN DayNumber = 1 {Start of first full day on the chart} ELSE DayNumber = MinList(DayNumber+1,DaysToAvg+1) ; {Start of a subsequent day, never goes above 21} // Reset cumulative daily bar and volume counters, since on first bar of a new day. CumVolToday = 0; BarsToday = 0; // Clear out array row number (days to average + 1) for today's data. Previously moved it into day 20 in the array. IF DayNumber >= DaysToAvg + 1 THEN For Value2 = 1 to BarsPerDay Begin VolArray[DaysToAvg + 1, Value2] = 0; End; END; {tasks for first bar of each day} IF Daynumber <> -99 THEN BEGIN // Increment bar and volume counters. BarsToday = BarsToday + 1; CumVolToday = CumVolToday + Volume; // Store today's cumulative volume into the array, in the column for this bar. VolArray[DayNumber, BarsToday] = CumVolToday; END; // Now calculate the 20-day cumulative average volume through this bar, if we have enough data. If Daynumber > DaysToAvg THEN BEGIN TotCumVol = 0; // Add up the cumulative volume through this time for each of the past 20 days. For Value3 = 1 To DaysToAvg Begin TotCumVol = TotCumVol + VolArray[Value3, BarsToday]; End; // And divide it by the number of days to get the average cumulative daily volume through this time of day. AvgCumVol = IntPortion(TotCumVol / DaysToAvg); // Now compare today's ccumulative volume to the average. VolPercentile = IFF(AvgCumVol > 0, CumVolToday *100 / AvgCumVol, 0); Plot1(VolPercentile-100,"VPctAvg"); Plot2(0,"100%"); //plot1(value1, "TotalCumVol"); //plot1(VolPercentile, "AvgCumVol"); //plot1((TotCumVol-CumVolToday)/AvgCumVol, "CumVolToday"); END; END;

bmtrading9,

what does your debugging show i.e. what happens within the code on realtime bars versus live data? Looking into this will be the first step in tracking the problem down.

I have to find it out how to debug in MC, If you plot it it will plot perfectly on historical min data but if you watch this indicator real time, plot is way different worst part is I don't even remember where I got this code, it looks like TS code.

It may be TS code, but none of the statements contain something that isn't possible in MultiCharts.

What are your indicator settings in real time? From your description, I suspect you're using the 'Update on every tick' setting enabled. With that option, the indicator processes every real time tick. Since MultiCharts indicators only calculate on the close of each bar on historical data, in effect your indicator will calculate differently on historical data (once per bar) than on real-time data (numerous times per bar).

I would disable the 'Update on every tick' option and then see how the behaviour in real time is. Here's more on that setting: Wiki: Update on every tick.

Thanks, that might be it I will verify it on Monday

Nope, didn't solve it. Same issue.

I have the same issue. Ticking off update every tick does not help. Can anyone help here?

sage08,

please describe the exact issue you are having and the explain the chart setup you are applying this indicator to (i.e. symbol, interval, amount of history etc. everything that would be required to reproduce what you are seeing).

hey did you ever get a working RVOL?
