Option 2: iterate over bars def process_bar ( bar ): # process bar print ( bar ) bar_iter = api. Option 1: wait for the data from alpaca_trade_api.rest import REST, TimeFrame api = REST () api. We provide you with both options to choose from. Wait for the entire data to be received, and then work with it as a list or dataframe.(meaning it's faster but you need to process each item alone) Working with data as it is received with a generator.You could query up to 10000 items, and the API is using a pagination mechanism to provide you with the data.
