MT-RSI

This script shows a "Multi Timeframe RSI" for a range. You could use this script to quickly detect if the RSI of the higher and lower timeframes are overbought or oversold.
RSI is relative to a lower timeframe. So 1H is relative to the 4H and the 4H relative to the 1D chart etc...

In this example you can see that the 1H timeframe (green line) is performing well but is in overbought territory, but the 4H timeframe (blue line) dit not perform that great relative to the 1H timeframe.
