I am getting this error when I backtest:
Runtime Error: Trying to retrieve an element from a collection using a key that does not exist in that collection throws a KeyError exception. To prevent the exception, ensure that the ANGI V1OBWK1IM6HX key exist in the collection and/or that collection is not empty.
at <lambda> in FundamentalUniverseSelectionModel.py:line 3
KeyError : 'the label [ANGI V1OBWK1IM6HX] is not in the [index]'
Would anyone be willing to look at my code and tell me what I am doing wrong? I believe it is in the #Top 1500 Volume section (because it worked before I added that).
