This idea behind this indicator was to show an un cluttered view of the RSI on 3 different timeframes. The RSI for the current chart highlights Lime/Red when it crosses the Overbought and Oversold levels, which are editable in the Inputs tab. RSI 2 defaults to the 1h timeframe and prints a lime dot at the top of the indicator when it's above the 50 level and a Red Dot at the bottom of the indicator when it's below the 50 level. It can also be viewed as a plot line that changes color when it's above or below the 50 level. RSI 3 defaults to the 4h timeframe and prints a blue square at the top of the indicator when it's above the 50 level and an orange square at the bottom of the indicator when it's below the 50 level. It also can be viewed as a plot line that changes color when it's above or below the 50 level.
I've added the indicator multiple times to show a few of the different viewing options, with the default settings at the very bottom.
