Plotting APPLE stocks in Python


I am new to QuantConnect and I would like to plot AAPLE ("AAPL") stocks. Also, I would like to get the latest price instead of entering 3/26/2018 manually. Can someone help me how do I it?

        '''OnData event is the primary entry point for your algorithm. Each new data point will be pumped in here.'''

Update Backtest

Hi Priyank Shah, Please see the attached sample algo. Basically if you don't set the end date, the backtest automatically runs until the latest day. Thanks. 


Hi HanByul P, 

Thanks, not mentioning the end date is what I was looking for. However, in order to get the stock data, you are using self.SetHoldings. What if I would like to get data without holding the equity?

Please let me know!


Hi Priyank Shah, Simply to get the AAPL prices, you need to use 'History' function. You can get 'Daily' data, 'Minute' data and so on. I attached a sample algo that shows how to get the AAPL daily 'close' and current 'close' at 09:35am. Please see 'Logs'. Thanks.
