Firefly Oscillator [LazyBear]

This is a modified version of a public Amibroker indicator, called Firefly.

I disabled the additional smoothing (you can enable it via options page) and updated the visual rendering (simple 3D look, histo, bar colors et al). Also, have added an option to show enclosing BB.

You can trade this like any other oscillator -- 80/20 OB/OS levels, divergences, ...

Here's a chart showing some possible customizations that are supported:

Do let me know what you guys think.
