Hi Tamim,
The Securities object behaves like a Python dictionary in regards to how we access it with keys. But under the hood, it's a C# class. Thus, when we iterate over it with
for kvp in algorithm.Securities:`kvp` is of type System.Collections.Generic.
That is why, in this case, we access the key and value with
kvp.Key kvp.ValueIf instead, we iterate over the object with
for kvp, val in self.Securities.items():`kvp` will be of type Symbol and `val` will be of type Security.
See the attached backtest and logs for reference.
Best,
Derek Melchin
