Hi,

I am running an algorithm with daily resolution using SPY500 constituents, and has been running very fast.

To have more accurate results I switched to QC500 rather than hardcoding the historical constituents. However, it runs very slow. Is there a way to make it calculate the fundamentals in a lower frequency. I suspect this calculation causes the algorithm to perform that slow. I am fine to do this once a month. 

Thanks,

Dario
