Which one is the correct AFL?

Hi!

I found these NMA AFLs. One is form the direct website of tatechnics and rest form the other sources. All the AFLs give different signals and/or different look, too.
It is claimed that all the ALFs are developed by Mr. Karthik Marar. Will any one help to confirm which AFL is correct, PLEASE? (It will be great help if Mr.Marar himself gives his opinion, PLEASE.)

Thanks.
