Trend Oscillator - Update

Hi Riders, we have updated our Trend Oscillator with a new a feature: Up and downtrend colors.

- Red: wave going down

- Green: going up

Seems to be more consistent than orange and blue circles, however circles are still valid when looking for confluence as those appear usually 1 candle before the wave changes color (but are less accurate during high volatility)

Made minor changes to the indicator settings, and added colors customization.
