LRS w/MA

[drizzi]

Alexis

I have an EFS you authored for LRS and I would really like to add a selectable MA to the plot. Unfortunately, I am a newbie and not versed in EFS. Can you please help me out.

Thanks

Some time ago I wrote an efs which will compute the MA, EMA or WMA of any user defined variable. You can find it here. In that same thread you can also find some examples of how it can be used with price and non price studies
Save it to the same folder in which you have saved the LRS study then open it with the Editor and replace line 52 which is
vUserVar = close();//(high(0)+low(0)+close(0))/3;
with
vUserVar = call("LRS.efs");
Once you have done that replace the return statement in line 98
return aMovAvg[MAOffset];
with
return new Array (vValue,aMovAvg[MAOffset]);
At that point you will need to add some statements in preMain if you wish to color the line differently or plot it in a different thickness etc. Look in the same thread mentioned above for the example using the cmf.efs

Are you sure about the EFS you directed me to?? The code doesn't match up with what you said. Look below;

Line 52 is;
if (aValue == null) aValue = new Array(MALength);

and Line 98 is a blank line. Actually, I couldn't find any lines that match up with the code in your post. Am I looking at the correct EFS??? I got it from the link you pushed and it had the right title.

Thanks

My apologies. The version I had on my system was a later revision that I had not posted.
I have now added it to the same thread.

No apologies necessary, you're the best.

Thanks again!!!

You are most welcome and thank you for the compliment

Hate to be such a pain Alexis, but I did everything you said with the new template but it doesn't plot. I'm sure it's something I'm not doing but I have to ask; is the EFS missing a return statement or something similar??

Doug
Post what you have done and I will look it over.
As far as I can tell the version I posted is not missing anything. Here below is what it should plot if you run it without any modifications

I attached the renamed EFS with the mods as per your instructions. Is it possible that renaming the file caused a problem?? The file appears to attach OK but there is no visible plot and I don't get any error messages.

There was another change that was required and that is setting the efs as a non price study. Also make sure that the script is in the same folder as the LRS.efs. All changes are commented in the attached revision of the script.
Here is what the plot of your modified efs looks like

OK, got it. I should have caught that but I'm still learning. I will try making some adjustments now based on the other script you referenced. Thanks once again for all the help.
