Hello!

I encountered the ff error in my program:

Runtime Error: Exception : Please register to receive data for symbol 'A RPTMYV3VC57P' using the AddSecurity() function...at CoarseSelectionFunction in main.py:line 113

CoarseSelectionFunction (lines 83 - 118):

def CoarseSelectionFunction(self, coarse):
        
        Initial_Universe = [x for x in coarse if x.HasFundamentalData]
        Filtered_Universe = []

       for x in Initial_Universe:
            ticker_symbol = x.Symbol
            #security_key = x.key
        
            #We only want equities that satisfy the following screening criteria
                #US stocks, min volume of last 50 trading days above 500K shares
                #Min price of $1 per share 
                #Min dollar volume of $2.5M over same 50 day time period

if x.DollarVolume > 2500000 and x.Price > self.value_MinStockPrice and x.Volume > 500000:    
                Filtered_Universe.append(x)
      
        #For every stock that satisfy the screening criteria, compute the RSI
        for x in Filtered_Universe:
            x.RS_Index = self.RSI(x.Symbol, self.value_RSIDays, Resolution.Daily)
        
        #Then, sort the stocks according to the highest RSI:
        Filtered_Universe.sort(key=lambda x: x.RS_Index, reverse=True)      

        return [i.Symbol for i in Filtered_Universe]

To fix the error, I put the ff. code in main.py under the initialize function:

self.AddSecurity(SecurityType.Equity,'A RPTMYV3VC57P', Resolution.Daily)

However, I still get the following error:

Runtime Error: Exception : Please register to receive data for symbol 'AA WF7IHVI76I5H' using the AddSecurity() function...at CoarseSelectionFunction in main.py:line 113

What is the best way to fix the error? 

Appreciate the response!
