Backtest including or excluding specific industries

[StephaneFima]

Yep. Just did some test (with the explorer) on my solution and it works perfectly well.
I think we were saying the same thing but coded differently.

However, as I said before, I always have some delisted stocks with no GICS number.
Therefore the results of a strategy using this snippet will have some bias (but I think it should be small).

And yes, your last solution works fine too

great

actually you can write the same thing in many ways i sometimes feel it depends on the mood how it will be simple or complicated

regarding delisted stocks you are right some of them they don’t have industry mentioned
