My model only holds a subset of the symbols I track. What is the best way to count the number of symbols currently held? Is there a count function, can I loop through self.Portfolio, or must I loop through all symbols tracked? I've tried several things but the only thing that works is looping through all symbols tracked but I think there must be a better way. Thanks for any help.

Hi Hugh,
To iterate all the stocks in the portfolio, you could use
for kvp in self.Portfolio:   security_holding = kvp.Value   symbol = security_holding.Symbol.Value # Quantity of the security held   quantity = security_holding.Quantity # Average price of the security holdings   price = security_holding.AveragePriceOr you can get the symbol list invested first
invested = [x.Key for x in self.Portfolio if x.Value.Invested]Then loop the "invested" to get the properties
for symbol in invested:     security_holding = self.Portfolio[symbol]     quantity = security_holding.Quantity     price = security_holding.AveragePriceHugh Todd
Jing Wu - Thanks, you're the best. You gave me several options that should work. Really appreciate it.
