Need help with multiple ma efs

[pmurraymc]

Hello,

I am writing a peice of code to display multiple price indicators - in this case MA s, I want to be able to enter in a blank value and the code just not display the MA in question - at present I get a message saying Invalid Length ...

Some help would be appreciated.

Thanks

Try the attached revision of your efs and see if it does what you are asking. Note that I only modified the first moving average as an example. Set its length to 0 and it will not display.

Thanks Alex, that works - I will expand the solution to the other MAs.

While doing that you can simplify the process by combining into one the two conditional statements I added to your script. See the example enclosed below
Alex

if(Length_1>0){
        if (vEma1 == null) vEma1 = new MAStudy(Length_1,0,"Close", MAStudy.EXPONENTIAL);
        var xEma1 = vEma1.getValue(MAStudy.MA)
    }else{
        var xEma1 = null;
    }
