# FVO_Fisher_CCI_Combo (ALSO Called FVO_RAF_UPPER)
# Recycled Indicators - combined by @cos251
# 2020.10.01 - The script will calculate then FisherTransform and CCI in combinationto generate signals
# indicating possible trend. The signals alone are not buy or sell signals but only a
# combination of two indicators to provide indication or trend as they relate to the two
# indicators mentioned.
# Signals GREEN UP ARROW - FT crossed above FTOneBarBack and CCI has crossed above +100
# CYAN UP ARROW - FT crossed above FTOneBarBack and CCI > CCI[1]
# RED DOWN ARROW - FT crossed below FTOneBarBack and CCI has crossed below -100
# RED DOWN ARROW - FT crossed below FTOneBarBack and CCI < CCI[1]
