> I've built many systems in this area, but it wasn't until I started working in the Indian market (>10 yrs ago) that it became abundantly clear that trying to calculate the long/shorts signals using historical (/time series) data was a waste of time. (And yet my primary role was to provide tools that did exactly that).

I'm currently working on building similar tools in my area of work for the Indian market and would really appreciate if you could shed some more light into the things you learned from your experience in working in this domain.
