I was wondering what specific steps have been taken to ensure the accuracy of QuantConnect's historical data? I realize that ensuring perfect accuracy down to every tick of every symbol is pretty unrealistic, but have attempts at least been made to remove inaccuracies in minute-to-minute data or even daily data? I'm not trying to imply that I have found anomalies in the data (I haven't).

I also wanted to say that I have only been a member of QuantConnect for less than a week and I already love it. QuantConnect is going to make life a million times easier for a beginner-level algo trader like me! Keep up the good work guys!
