# Need to understand how I can add more indicators if I want - struggled with warming up onData. Tried adding more indicators using for symbol, sma in self.data.items(): but it didn't work

# FOR JOVAD NEW SESSION: HOW TO PICK STOCKS WITH HIGHEST 


# FOR JOVAD 6/29- NEW STRATEGY TO TEST: IF RSI PREVIOUS CLOSE < RSI CURRENT CLOSE ENTER TRADE ELSE EXIT TRADE, TRAILING STOP 5% HOURLY CHART
# STOCK PICKING HOUR SMA NEEDS TO BE ADJUSTED TO CRYPTO AS WELL WITHOUT UNIVERSE SELECTION + FIX EXCHANGE IS CLOSED ERROR
# ALSO FOR STOCK PICKING - WE NEED TO ADD FUNCTIONALITY TO REMOVE MANUALLY SELECTED TICKERS LIKE GOOG AND GME
# ASK FOR ADVISE IF WE CAN FIND A LOGIC TO EXCLUDE DANGEROUS TICKERS LIKE AMC AND GME
