symbols = ["MON", "AAPL", "CSRA"]
for symbol in symbols:
qb.AddEquity(symbol)
end_date = datetime.now()
start_date = end_date - timedelta(days=60)
history = qb.History(symbols, start_date, end_date, Resolution.Daily)I'm running the above code in a notebook. If I try to do any of these, I get an error.
history.loc["MON"]
# KeyError: 'the label [MON] is not in the [index]'
history.loc["CSRA"]
# KeyError: 'the label [CSRA] is not in the [index]'
history.loc["AAPL"]
# works fineBoth MON and CSRA appears to be in your available daily data:
https://www.quantconnect.com/data/file/equity/usa/daily/c*/csra.zip/csra.csv
https://www.quantconnect.com/data/file/equity/usa/daily/m*/mon.zip/mon.csv
How comes this crashes my notebook?
Thanks!

Same error for TWX and WYN. Haven't found anymore of these in the S&P500...

Hi Joseph,
Data for MON and CSRA are updated until 06-06-2018. Therefore if your request the history for the last 60 data, the data frame returns nothing. The last data point of TWX is on 07-14-2018 and WYN on 05-31-2018. These companies were acquired or merged by the other companies and no longer listed in the market. You can expand the time range to get the history data of those companies.
