I'm new to the Quantopian environment. The Quantopian Help descriptions don't provide detail on available SIDs or use of History with multiple SIDs declared. I've searched the community posts and haven't seen usable examples.
If I use a market index as part of my technical indicator suite, how do I find a SID for an market index? If I apply the History method to retrieve stock and index pricing, how do I declare a specific SID to limit pricing retrieval given the differences in pricing information between a stock and an index?
Thanks!
