# 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
# Adjusted for compatability with scanner based on Mobius' notes. 7-14-19 Markos
