Stochastic with Bollinger & EMA

In this script
I combined the various of the oscillator
Stochastic (STOCH) with BB (Bollinger Bands).

Each cut of K and D creates a mark (+) Red / green - accordingly.

As the Stochastic (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 EMA - it is possible that this is a clear sign of an increase.

Band 50 was also added to facilitate the calculations.
