Hi,
I am Sourabh Jain, I have written Thinkscript based on (1) swing point based trendlines (2) Belajar GUPPY GMMA (2) Fibonacci retraces (4) pivot point (5) Heikin Ashi based alert (6) Gann swing, for the clients on freelancer. Please check my portfolio for images of the works. I am quite good at Thinkscript and do this particular task effectively with my experience on TOS. If you like to discuss this further, please let me know.
