How do I get the SAR value in an EA that is plotted to the chart?

New comment
 
I would like to get the current SAR value that is plotted to the chart.

double SARCurrent = iSAR(NULL, 0, SARStep, SARMaximum, 0);

This call doesn't seem to get this value.

Any help would be appriciated.

Thank you.
 
Perhaps using the Symbol() function without arguments rather than NULL will work?
 
NULL just uses the current symbol of the attached chart. I've tried it both ways, actually and they behave the same. I am getting a value, it's just not the value that is plotted to the chart.
 
Killings,

be sure "SARStep" and "SARMaximum" are double variables.
