RSI Indicator (multi-timeframe)

RSI indicator that lets you show a second timeframe. Blue is the current timeframe, red is the "other" timeframe you select. TradingView allows you to input any timeframe, but it generally works best with a longer timeframe than what your chart is using. (E.g. use the 1-hour timeframe along with a 15-minute chart; or the daily timeframe along with a 1-hour chart; or the weekly timeframe along with a daily chart.) This will help you spot divergences at multiple timeframes.

You can turn off the Multi-Timeframe and just use it as a basic RSI indicator. There's an optional signal line for the current timeframe, and optional overbought/oversold highlights on both timeframes.
