preload_data(client, create_trading_universe, universe_options)[source]#

Show nice progress bar for setting up data fees for backtesting trading universe.

  • We trigger call to create_trading_universe before the actual backtesting begins

  • The client is in a mode that it will display dataset download progress bars. We do not display these progress bars by default, as it could a bit noisy.
