This script showcases the new (overload) feature regarding the fill() function! 🥳
2 plots could be filled before, but with just 1 colour per bar, now the colour can be a gradient type.
In this example we have 2 plots - rsiPlot , which plots the rsi value - centerPlot, which plots the value 50 ('centre line')
Explanation of colour fill in the zone 50-80 Default when rsi > 50 - a bottom value is set at 50 (associated with colour aqua) - and a top value is set at 80 (associated with colour red)
This zone (bottom -> top value) is filled with a gradient colour (50 - aqua -> 80 - red)
When rsi is towards 80, you see a red coloured zone at the rsi value, while when rsi is around 50, you'll only see the colour aqua
The same principle is applied in the zone 20-50 when rsi < 50
