I combined the various of the oscillator
( ) with BB ( ).
Each cut of K and D creates a mark (+) Red / green - accordingly.
As the (K) crosses the BB base, a green / red point is formed accordingly.
As a sign it is possible to continue up / down.
I added EMA8 to K (style circles)
When the oscillator is above the - it is possible that this is a clear sign of an increase.
Band 50 was also added to facilitate the calculations.
