I have been using this free ATR based RSI indicator for a while and it's fantastic. It cleanly captures the shift in momentum and displays Green and Red lines. Green = Long, Red = Short and Gray = Do nothing.
It also has regular RSI line but I hide it to avoid confusion. Here is the link If any one needs it.
