Analyzing Stocks in Research That Share a Symbol by Derek Melchin

After analyzing the CSV file of tickers provided by QuantQuote in the Data Library, I've noticed that it's possible for seperate companies to trade under the same symbol in this dataset. For example, both Astra and Agilent Technologies have used the symbol 'A'.

My question is: in the Research environment, is it possible to retreive the historical pricing data for both of these securities?

As of right now, I'm only aware of retrieving historical pricing data with

qb.History(qb.AddEquity("A").Symbol, 250, Resolution.Daily)

which only returns the data for Agilent Technologies (the currently listed stock). Ideally, I'd like to analyze the historical data of both of these companies.

For anyone else who may be experiencing the same thing I am, rest assured. If you call the History method with dates that include when each of the companies were listed, their time series of historical data are stitched together in the DataFrame that results.
