Introducing the new Market Summary File Lookup!

Our new market summary file lookup offers a snapshot of the entire market every 5 minutes throughout the trading day! Deliverable by exchange and security type, these lookups contain data for every symbol we carry streamed to you over the lookup port in IQFeed. At the end of the day, they are archived for historical EOD retrieval. Additionally, via these lookups you will be able to retrieve archived fundamental data. Data has been backfilled for this new product offering back through May 20th, 2018. Note that exchange permissions for real-time vs delayed 5min snapshot files are still in effect for this product and we are still evaluating what price point this will be when the beta period ends (for now, it’s free).
