Exponential Volume EFS

[KuJaX]

I have recently searched file sharing for EXPONENTIAL VOLUME and the only thing that looked like it was

" ema_vm.efs" in "TSSUPPORT"

However, it doesnt plot it WITH the volume (so the lines go on top of the volume bars)....

is there a study that plots it actually on volume??

Not quite sure of what you are asking.

If you want to plot Volume and an EMA of Volume then click here and download VolumeMA.efs.
Through Edit Studies you can set the length, type of MA (Simple, Exponential, Weighted, Volume Weighted) and how the Volume bars are colored ie if based on price or Volume (see first image below)

If instead you want to use the efs from TS Support and also plot the Volume bars then the attached revision of that efs should do what you want (see second image below).

Alexis,

The top picture is exactly what i'm talking about. I downloaded the EFS that you said. Thanks a lot! Exact!

Alexis,

We may have a little problem after going through it.

I have gone in and edited line 17 to

setDefaultBarFgColor(Color.yellow, 1);

This has made the color of the MA yellow. However, what the problem is, is that I want the volume bars RED for selling and GREEN for buying. The way it is setup it has BLUE for buying and RED for selling. I cannot find in the coding anything to edit that.

The code that colors the volume bar is set up depending on what you select as the Source in Edit Studies and is contained in the following lines of the script.
If you select "Price" as the Source then (see lines 52-59)

if(Source=="Price"){
        if (close() < open())
            setBarFgColor(Color.RGB(255,0,0));//RGB value is for red
        else if (close() > open())
            setBarFgColor(Color.RGB(0,0,255));//RGB value is for blue
        else if (close() == open())
            setBarFgColor(Color.RGB(0,0,0)); //RGB value is for black  
    } 

The same happens when Volume is the Source (lines 60-67)

if(Source=="Volume"){
        if (volume() < volume(-1))
            setBarFgColor(Color.RGB(255,0,0));
        else if (volume() > volume(-1))
            setBarFgColor(Color.RGB(0,0,255));
        else if (volume() == volume(-1))
            setBarFgColor(Color.RGB(0,0,0));
    } 

Instead of Color.RGB(255,0,0) you can also write Color.red
In the EFS Help Center & Library you can find a list of the basic colors under EFS Function Reference->Colors, Constants and Flags->Colors

Okay, cool got it setup. Thanks a lot! This is a lot of help.
