Hello, In what forum should data science topics be posted? For example, where would I post about structure and analysis of data sets in a pair trade (GM/F, AG/AU, VZ/T, etc.), including datasets such as market price, options at various strikes, futures at different contract expiry, etc. This is a little esoteric for the "Trading" forum, is beyond "Technical Trading," and doesn't fit well in "App Development." Thanks, Keith
