gann square of 9

I will update Crude oil trading based on GANN square of 9 strategy daily. Please update your suggestions and feedback if any.

Hi All memebers, I found an AFL from net plotting lines for levels of Gann Square of 9. I am trying to make changes so that lines show up only for current day. And just 3 lines above and 3 lines below the previous days close. AFL seems to be very tricky for me. Please help me...
