#EMA - RSI Alert
# alerts would be as follows:
# On the 5 min chart i use the following ema's
# 9 13 34 50 72 89
#The long alert is
#If the 34 is above the 50 and
#50 is above the 72 and the
#72 is above the 89 and
#The RSI is below 60 and
#The RSI is above 30
#Send Long alert if the last price is = to the 89 ema
#The short alert is as follows:
#If the 89 is above the 72 and
#The 72 is above the 50 and
#The 50 is above the 34 and
#Rsi is below 60
#Send short alert is last price is = to the 89 ema
