Please help: How to isolate out one equity?

you can add: 

and symbol.Value == “QQQ” 

to list condition to only choose “QQQ”. 

Or you can save SPY/QQQ symbol earlier when you add securities, like in initialization:

self.qqq_symbol = self.AddEquity("QQQ").Symbol

and compare symbol directly, without Value.

I have the following code in my initialize section.  I thought if I referenced your self.qqq_symbol and I owned a QQQ call, a QQQ put and QQQ stock that it would pull all three.  Maybe it will just pull the equity only and not the options.  I'll check that and see.

self.equityqqq = self.AddEquity("QQQ", Resolution.Minute)
self.equityqqq.SetDataNormalizationMode(DataNormalizationMode.Raw)
self.symbolqqq = self.equityqqq.Symbol

If I add that code I get an error, I tried to ("QQQ") also, same thing:

Build Error File: project/main.py Line:105 Column:120 - SyntaxError: invalid character in identifier

investedQQQequity = [symbol for symbol, holding in self.Portfolio.items() if holding.IsLong and symbol.Value == “QQQ” and holding.Type == SecurityType.Equity]

Build Error File: project/main.py Line:105 Column:120 - SyntaxError: invalid character in identifier

I think your quotes around QQQ are not standard ones. Try typing them, not copy and paste from here. Maybe formatting here replaces regular quotes with non-standard ones.

Good eye, thanks.  I thought it was an error in the code but it was just the quotes, the cut and paste put in some weird quotes.  

Thanks again for your help! worked great!
