Mobius' notes:

RSI Laguerre is one of the all time favorites in the opinion of many in The Thinkscript Lounge. TheoTrade has a YouTube video on this with "indicator finds tops and bottoms" in the description.

Alerts are baked into the new (7-14-19) version below!!

Both Fractal Energy and RSI are plotted. RSI in cyan and FE in yellow. Look for trend exhaustion in the FE and a reversal of RSI or Price compression in FE and an RSI reversal.
