When I run the following code using a period it works: self.spy_history = self.History(self.spy_symbol, 30, Resolution.Daily)
When I try with start_time an end_time I get an empty dataframe: self.spy_history = self.History(self.spy_symbol, start_time, end_time, Resolution.Daily)

you cannot get history from the future counting from current algorithm Time, algorithm starts on 2008-01-01 00:00, so your first history call will return last 30 days history up to (excluding) this date (basically, December 2007), while the second call will try to retrieve history from the future relative to current date, which is 2008-01-01, and will return none.
