Getting historic cypto values

Hi Keith,

To get historical data for a crypto coin, you can use the History method in QuantConnect. This method returns a pandas DataFrame with historical data of the requested symbol. You can specify the period for which you want the data. For example, if you want data for the last 2 hours, you can use self.History(symbol, timedelta(hours=2)).

Here is an example of how you can use this to implement a strategy where you check if the value of a coin is increasing over the last 2 hours and buy it if so:

class MyAlgorithm(QCAlgorithm):
    def Initialize(self):
        self.SetStartDate(2013,10,7)
        self.SetEndDate(2013,10,11)
        self.AddCrypto("BTCUSD", Resolution.Hour)
        self.Schedule.On(self.DateRules.EveryDay("BTCUSD"), self.TimeRules.Every(timedelta(hours=2)), self.CheckPrice)

    def CheckPrice(self):
        history = self.History(self.Symbol("BTCUSD"), timedelta(hours=2))
        if history.empty:
            return
        if history['close'][-1] > history['close'][0]:
            self.SetHoldings("BTCUSD", 1)

In this example, we schedule the CheckPrice method to run every 2 hours. In this method, we get the historical data for the last 2 hours and check if the closing price has increased. If it has, we set our holdings of the crypto coin to 100%.

As for more examples of crypto strategies, you can check out the Strategy Library on QuantConnect. It contains a collection of tutorials written by the QuantConnect team and community members, which include strategies for cryptocurrencies.

You can also check out the QuantConnect forum for discussions and examples of crypto strategies shared by the community.

I hope this helps! Let me know if you have any other questions.
