# RSI-Laguerre Self Adjusting With Fractal Energy Gaussian Price Filter # Mobius # V01.12.2016
# 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.
# Rename Study to RSILg_FE_Gssn1 for compatability with Scanning
