add vertical Grey line at alarm point?

[jand1]

Hi,

I have an efs that sounds an alarm at a low volume point.
I would also like the formula to draw a vertical light grey line on my price chart at this point as well?
Any suggestions?
Thanks you

EFS does not plot in two panes at the same time. To accomplish what you are trying to do you need to create a second version of your efs that is set up as a price study that does not plot the volume and its average and that just draws the vertical line [when the conditions are met].
To do this you need to replace the following statement in the preMain function

setPriceStudy(false); 

with

setPriceStudy(true); 

Then replace the return statement ie

return new Array (volume(),MAofVol); 

with

return; 

At that poiint you need to add a command to draw the lines when the condition is met. For example if you want to draw the lines when Volume is greater than the average you would modify this section of code

if (getValue("rawtime",0) != nLastRawTime1) { 
        if(volume()>MAofVol){        
        Alert.playSound("ding.wav");
        Alert.addToList(getSymbol()+"  "+getInterval(),"Volume Alert 1",Color.black,Color.blue);
        nLastRawTime1 = getValue("rawtime",0);
        }
    } 

to the following

if (getValue("rawtime",0) != nLastRawTime1) { 
        if(volume()>MAofVol){        
        //Alert.playSound("ding.wav");
        //Alert.addToList(getSymbol()+"  "+getInterval(),"Volume Alert 1",Color.black,Color.blue);
        drawLineRelative(0,0,0,Infinity,PS_SOLID,1,Color.lightgrey,rawtime(0));
        nLastRawTime1 = getValue("rawtime",0);
        }
    } 

In this example I commented out the alerts and added the command to draw the line. Apply the same logic to the other section if you want the lines to be drawn when Volume is less than the threshold
