Prepare Your Watchlist
Organise the stocks you want to monitor as the regular trading session approaches.
Premarket prices do not determine where a stock will open or trade during the regular session.
Understand Premarket Trading Risks
Premarket trading can involve lower liquidity, wider bid-ask spreads and greater price volatility than regular-hours trading.
Displayed prices may also differ between trading venues, and the quoted price may not be available when an order is executed.

Questions about the premarket session
- What time does premarket trading start?
- The session runs from 4:00am Eastern to 9:30am. Individual brokers set their own start times and many do not accept orders before 7:00am.
- Can anyone trade premarket?
- Most US brokers allow it once you enable extended hours on the account. Order types are usually limited to limit orders, and some brokers cap order size.
- Is premarket a good predictor of the open?
- Weakly, and less so the thinner the volume. Direction holds more often than magnitude, so a stock up eight percent premarket frequently opens up two.
- Why are premarket spreads so wide?
- Fewer participants means fewer resting orders. With a thin book, the gap between the best bid and the best offer widens, and a market order can fill far from the last price.
- What moves stocks in premarket?
- Earnings released before the open, company announcements, analyst rating changes, and overnight news from other markets.
