This is a follow on to my Multi-Timeframe RSI indicator. In that indicator, you could keep an eye on RSI values above your current time frame. This one allows you to look at RSI levels below your current timeframe. The idea behind this one is you may want to "buy the dip," so you can look for oversold conditions on lower time frames expecting a bounce to occur.
There is one issue with this indicator is that it takes awhile to load. Seems to be pretty resource intensive, so I tend not do use it. It will get annoying if toggling fast between tickers due to the speed in which it loads.
