Hey Sujit,
I hadn't came on this thread since then. Here I've uploaded the excel file for the benefit of you and other users whomsoever need this. Enjoy and must also thank Radha. Links for download are below.
Hi, Jinjin
Thanks for the Excel to calculte Gann levels, but it requires passward to unprotect the sheet. Please provide the passward, so, that we can use it.
Thanks,
