As suggested by many, I added "Fuchsia Cross" for sell signal which is using the similar algorithm of "Yellow Cross". Labels and alerts are added.
SELL label --> standard sell
BUY label ---> standard buy
GBUY ---> Golden buy
FSELL ---> Fuchsia sell
Alert on Yellow BUY ---> YBUY!
Alert on Fuchsia BUY ---> FSell!
Alert on BUY ---> BUY!
Alert on SELL --> SELL!
