I have a radarscreen with various symbols, all with a 5 minute interval.
i want to add an indicator to display the Average Daily Volume for the last 20 days.
how can i access historical daily volume in easylanguage?

Try this Volume Avg indicator modified for RS. Adjust the input for AvgLength to longer periods e.g. 20 days x 390min /5 on 5 min charts; 390min is 6.5 hrs Reg Trade Hrs.

inputs:  
	AvgLength( 30 ),  
	AlertPct( 50 ),  
	UpColor( Green ),  
	DownColor( Red ) ; 
 
variables:  
	VVol( 0 ), 
	AvgVVol( 0 ), 
	TVol( 0 ), 
	AvgTVol( 0 ), 
	AlertFactor( 1 + AlertPct * .01 ),  
	AlertStr( NumToStr( AlertPct, 2 ) ) ; 
 
if BarType >= 2 then { ie, not tick/minute data } 
	begin 
	VVol = Volume ; 
	AvgVVol = AverageFC( Volume, AvgLength ) ;  
	Plot1( VVol, "Vol" ) ; 
	Plot2( AvgVVol, "VolAvg" ) ; 
	{ Alert criteria } 
	if VVol crosses over AvgVVol * AlertFactor then 
		Alert( "Volume breaking through " + AlertStr + "% above its avg" ) ; 
	end 
else { if tick/minute data; in the case of minute data, also set the "For volume,  
 use:" field in the Format Symbol dialog to Trade Vol or Tick Count, as desired } 
	begin 
	TVol = Ticks ; 
	AvgTVol = AverageFC( Ticks, AvgLength ) ; 
	Plot1( TVol, "Vol" ) ; 
	Plot2( AvgTVol, "VolAvg" ) ; 
	{ Alert criteria } 
	if TVol crosses over AvgTVol * AlertFactor then 
		Alert( "Volume breaking through " + AlertStr + "% above its avg" ) ; 
	end ; 
 
{ Color criteria } 
if UpTicks > DownTicks then  
	SetPlotColor( 1, UpColor )  
else if UpTicks < DownTicks then 
	SetPlotColor( 1, DownColor ) ;

thanks for the response.

so on a minute chart i would use 7800 as the AvgLength to get the 20 day average daily volume. i would also need to set "bars back" to 7800.
will this effect performance significantly?

I doubt it will affect performance. You will find that a 20 day moving average of volume is a pretty much a flat line (look at it on a chart) on a minute chart.
