Smaller Fractals (+ Transparency)

I find that fractals are super useful, but can visually clutter up the chart pretty quickly. Their opaqueness and just overall bigness can become a bit much.

As such, these are just like regular fractals, only smaller (pine script’ssize.tiny instead of the default size.small).

Also, you can set a transparency level to these little guys (default is 50%).

Simple, more polite, and hopefully more useful fractals for those wnting a cleaner looking chart.
