From the documentation, I learn the following way to add individual equity; but is there way to add the whole universe without adding each symbol?  For example, I want to add all symbols = MorningstarSectorCode.Technology, and search for tech stocks that meet fundamental criteria overtime.    What would be the best approach? Thanks


qb = QuantBook()


for symbol in symbols:

history = qb.History(qb.Securities.Keys, 253, Resolution.Daily)
