Indicator: Forecast Oscillator & a BB extrapolation experiment

FOSC (Forecast Oscillator, %F) is implemented as explained by Kaufman (there are lot of representations out there, using linregs, this one is not.).

This indicator plots a 3-period smoothing of %F. When %F = 0, the trend line and prices are moving parallel to one another; when %F is above 0 the market is accelerating away from the trend line; when %F is below 0 prices are slowing down and the two series are converging.

Now on to the BB extrapolation: As you can see above, a 21-period BB on 1W shows 2 volatile areas of same length. Simple projection using the same time periods gives us a similar volatile area in another 105d. FOSC is forming a similar pattern now as of the first area. More information in the chart markings.

Interesting thing for me was how my other chart (tradingview.com/v/HeSyTev8/) aligned with this. Lets see how far these timelines are respected.

In the mean time, feel free to "Make mine" this and use FOSC in your charts. Appreciate any feedback / comments.
