Hi, I'm writing a very basic algorithm, still in alpha version. Basically, the algorithm analyze 50 stocks and then decide which to trade based on certain parameters. I detected that those parameters might have no sense on those days where a stock have its earning reports as those are "not ordinary days" for a stock if you know what I mean. My algorithm will be much greater and less risky mainly if I can get from somewhere a datasource with stocks earning reports days. Can you help me finding that? I look in Quandl but I couldn't find. Any help?
