Questions on fib arcs, fans, and time series and confluence

Hello all.
I'm a forex newbie. . .in my readings\research I've struck many references to using fib lines\pivots\supports\resistances and confluence. I've,however, struck very little with regard to fib arcs and fans.

I really don't find any reason why fib arcs and fib fans can't be utilized
as a means of confirming confluence.

I'm wondering if anyone out there has used or uses fib arcs and fib fans (or even Gann squares and projections) and can shed any light onto the topic of their use and specifically depending on confluence.

On my next question:

I also often see people using confluence with respect to the y-axis (vertical direction). Can we use confluence using Gann charts and fib time show in the x-axis direction too?

For example (and I'm completely pulling this one from my ss). Say bollinger bands have shrunk, which decreasing coincides with a fib time show lineup and\or Gann square border, could this thought as confluence in time (as opposed to price)? And could be employed to trade?

Any help would be greatly appreciated,
