Viewing information from Technology Universe

Hello, I am having troubles trying to get a list of all symbols in the Technology Universe. I started a new algorithm with the Technology Universe Module (which comes with the TechnologyUniverseModule.py and self.SetUniverseSelection(TechnologyUniverseModule()) in the Initialize()). May I know how to access information from all the assets in the Technology Universe?

Hi Soggeh,

After a universe selection, we subscribe to all the symbols that we selected. By subscribing, the data of those symbols will arrive in the next data slice{}, which will be handled by OnData() method. Moreover, we could manage the change of universe in OnSecuritiesChanged() method. You might find more helpful information in our documentation page.

In the backtest I logged the ticker name of the securities in the universe in Ondata() method. Although in the chosen time range, there is no change in the universe based on Technology Universe Module selection, I've put code there in OnSecuritiesChanged() method to demonstrate how to log the ticker name of securities added to & removed from the universe (in OnSecuritiesChanged()). You could access whatever properties you want (OHLC, etc).

Hope it helps!
