Calculate Parabolic SAR

[werosen]

I'm trying to calculate a Parabolic SAR using the following:

var LongTermSAR = sar(.02, .02, .2, 400T);

It tells me I have a syntax error when I load the study.

Can someone tell me the correct syntax to use to specifiy 400 ticks as the interval?

Thanks

The syntax is sar(.02, .02, .2, inv("400T")).
FYI the customParabolicSAR.efs which is in the EFS2 Custom folder in Formulas is already preset for use with external symbols and/or intervals
