Parabolic SAR price source

[tbfx]

Hi everyone,

How do I define the price source of a Parabolic SAR? I want to specify a MA as source, but it pics up main symbol as source by default.

var study1 = new MAStudy(12, 0, "Close", MAStudy.EXPONENTIAL);
var study2 = new MAStudy(21, 0, "Close", MAStudy.EXPONENTIAL);
var xPARstudy = sar( 0.015, 0.015, 0.200, study2);

Any help would be appreciated.

Kind regards,

You need to use the ema() function and not the legacy MAStudy() function to do that
For the description and syntax of the ema() function see the EFS KnowledgeBase
As an aside in 11.5 you can accomplish the same without the need of an efs by applying studies on studies using the Built-in Studies

Alex,

Thanks for your quick response. Do I understand you correctly ... are you saying I need to make the following change?

var study2 = ema(21);
var xPARstudy = sar( 0.015, 0.015, 0.200, study2);
