Why is my self.History(1, Resolution.Daily) giving me 12-17 when the log shows 12-19? I have attached a debug to see in the log for reference. 

I know that my start date is 12-18, but the log doesn't throw the debug until 12-19 (also - why not 12-18?) so shouldn't my debug with self.time[-1] for self.History return 12-18 in that case? 

Any help would be greatly appreciated!
