Documentation - arguments by Christian Yapur

Hi.

I have been doing some analysis for stocks, and I would like to specify the interval time when importing:

qb = QuantBook()



# Select asset data

apple = qb.AddEquity("AAPL")

tsla = qb.AddEquity("TSLA")

googl = qb.AddEquity("GOOGL")



# Gets historical data from the subscribed assets, the last 360 datapoints with daily resolution

stocks = qb.History(qb.Securities.Keys, 360, Resolution.Daily)



stocks.head()

This gives the past 360 daily data, and I'm looking for 1-1-2018 to 1-1-2019. Specifically, I would like to know (for future questions) how to access to the documentation for this specific method. I have tried with "help(qb.History)", searching "qb.history" in the documentation, among others, and none of them gives me the arguments of this function/method.

Hi Christian,

Here is how to request historical data between two specific dates:

stocks = qb.History(qb.Securities.Keys, datetime(2018, 1, 1), datetime(2019, 1, 1), Resolution.Daily)

Here is documentation of Lean, the trading engine which powers QuantConnect platform. There is a “search” tab on left side panel. The documentation page of History() method is here. Moreover, you could fine some examples in our QuantConnect documentation page.

Hope it helps!
