you can use fibs with whatever... but gann is basically just even handle numbers with the ability to break them down nicely and have angles running off of them... the FIB A NAH C (not fibAnotchy) goes INSIDE your range and WHEN its done correctly, you'll get the NAN error... like you see here. from the .618 to the zero point of the year in this case... this is SUPER foundational base level stuff to build VALID complex harmonic multi-dimensional geomtry....i suggest using a scale, but to each their own :D
