QUANTCONNECT COMMUNITY
Hi Everyone,
For my algorithm I require to compare open prices for CFDs for previous 10 days open. I was reading about the self.history method, however, I am unsure of how to use it exactly.
How do I get the code to 'print/show' the value for historical open. Or more generally, how do I just print out the structure i get when i run the self.history method.
I hope that makes sense?

Here is an example of a History Request in Python:
def Initialize(self): ticker = "XAUUSD"; self.SetStartDate(2017,1,1) #Set Start Date cfd = self.AddCfd(ticker, Resolution.Minute, Market.Oanda) # History method returns a dict with a pandas.DataFrame history = self.History([ticker], 10, Resolution.Daily) # prints out the tail of the dataframe self.Log(str(history[ticker].head())) for index, row in history[ticker].iterrows(): self.Log(str(index) + str(row))Note that we need to pass the ticker in a list to have a pandas.DataFrame as output.
