I found the following code on tradestation forums. It's supposed to show the average volume and median volume by timeframe for a specified number of days back. However, the results don't line up with my calculations so I figured I would see if some experiences coders in here could have a look and see what's wrong. Here's the code:



INPUTS: Days.Back( 5) ;

VARIABLES: Days.Count( 0 ),
Session.Minutes( 0 ),
Total.Volume( 0 ),
Volume.Average( 0 ),
Volume.Median( 0 ),
Counter( 0 ),
Bars.per.Day( 0 ) ;


IF BarType = 1 THEN BEGIN { plot intraday time charts only }

Session.Minutes = TimeToMinutes(1515) - TimeToMinutes(0830) ;

Bars.per.Day = Round( ( Session.Minutes/BarInterval )+ 0.49, 0 ) ; { round-up }

//print(Counter);
//print(barnumber);
//Print("*******");

Total.Volume = 0 ;
Days.Count = 0 ;

FOR Counter = Round( BarInterval * 0.5, 0 ) TO Days.Back * Bars.per.Day BEGIN

IF Time = Time[Counter] AND
Days.Count < Days.Back THEN BEGIN
Total.Volume = Total.Volume + UpTicks[Counter] + DownTicks[Counter] ;
Days.Count = Days.Count + 1 ;
END ;

END ;
if Days.Count <> 0 then
Volume.Average = Total.Volume/Days.Count ;

Volume.Median = median(Upticks + Downticks,Days.Count);

Plot1( Volume.Median, "Median Vol" ) ;

Plot2( Volume.Average, "AvgVol(ToD)" ) ;

Plot3( UpTicks + DownTicks, "Volume" ) ;
if upticks > downticks then
setplotcolor(3,green);
If plot3 > Plot1 and plot3 > Plot2 then Alert("High Volume");

END ;

what instrument and what time frame is your chart?
what is it off by?
