Frequently asked questions
- Does Polygon offer pre-market and after-hours data?
- Yes, we provide data for every single trade that occurs, whether that happens during normal trading hours, or extended trading hours. Our tick-level market data will stream normally during pre-market and after-hours.
- How does Polygon create the OHLCV (open, high, low, close, volume) aggregate bars?
- Polygon uses the "Sale Conditions" attached to each trade to determine if that trade is eligible to update the aggregate.
- Where does Polygon's Stock data come from?
- We receive data directly from both SIPs (Security Information Processors) as RAW binary feeds rather than via retransmission or through an intermediary.
- Does Polygon offer dark pool data?
- Yes, we provide dark pool data. If a trade comes through with an exchange ID of 4 (exchange:4) and also has an attached “trf_id” field, it came from a dark pool.
