10x Data Scraping with AsyncIO / Concurrency
We use Asyncio to speed up the download of financial data from a REST API. In this video I use Polygon to download 1 minute OHLC candles, but the same technique will work for any provider.
We use a Queue to concurrently download multiple chunks of data at the same time, asynchronously using asyncio.
