The error message you're seeing is typically due to trying to use a symbol that hasn't been added to your algorithm using the
AddSecurity()orAddEquity()function. In your case, it seems like you're trying to use a symbol 'CMCSA' that hasn't been added.You should add these securities using the
AddEquity()function before creating the EMA indicator. Here's how you can modify your code:This will ensure that the symbol you're trying to create an EMA for is added to your algorithm.
Also, please note that Python doesn't support method overloading like C#, so if you have two
OnDatamethods in your code, the secondOnDatamethod will overwrite the first one. You should remove or rename one of them.Sources:
