What this script says

Gradient RSI Candles is an indicator drawn in its own pane.

You can change one input: `length` (default 14).

It calculates `strength` as the RSI over `length` bars and `tint` as the gradient (value `strength`, low red, high green, from 30, to 70).

On the chart, it draws a pane, draws a candles, plots `strength`, draws a horizontal line at 70 and draws a horizontal line at 30.
