MA Ribbon R2 by JustUncleL

This indicator plots and colour codes a ribbon between two moving averages. The colour of the ribbon changes with trend direction: when price in uptrend ribbon colour is green; when price in downtrend ribbon colour is red.

Options Available:

1) You can select between 11 different types of moving averages, each MA line can be a different type.

2) Option to display coloured Candles around the Ribbon, the colouring uses the Grab candles colour scheme:

• Lime = Bull candle closed above Ribbon.
  
• Green = Bear candle closed above Ribbon.
  
• Red = Bull candle closed below Ribbon.
  
• DarkRed = Bear candle closed below Ribbon.
  
• Aqua = Bull candle closed inside Ribbon.
  
• Blue = Bear candle closed inside Ribbon.
  
  

3) Option to base the candles on a higher time frame (HFT), this performed by increasing the MA length to create equivalent lengths from the HFT. So no re-painting.
NOTE: The script will time out if the MA lengths get too long after resizing.
