MFI & EMA & Bollinger Bands

In this script
I combined the various of the oscillator
MFI ( Money Flow Index ) with BB ( Bollinger Bands ).

As the MFI 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 MFI (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.
