Parabolic Sar refinement

 

Hi all,

I use Renko charts for trading and although not absolutely essential, I use the attached version of the Parabolic Sar indicator for direction.

I'm also a cautious trader!

Would it be possible for a coder to code the indicator so that it will only 'alert' on the third Sar dot? I'm willing to pay for success!
