What Is a Day Order?
A day order is a buy or sell order that automatically expires if it is not executed by the end of the trading session on the day it was entered. It is the default time-in-force instruction for most brokerage platforms.
When you place a trade, you must tell the broker not just *what* to buy and *at what price*, but *how long* to keep the order active. This duration is called "Time in Force." The default duration on almost every trading platform is the "Day Order." A day order remains active in the market until the closing bell rings. In the US equity market, this is typically 4:00 PM Eastern Time. If the order has not been filled by then—perhaps because the limit price was never reached—the broker's system automatically cancels it. The next morning, the order book starts fresh. This automatic cancellation is a safety feature. It prevents a scenario where a trader places a buy limit at $100, the stock closes at $105, and then two weeks later bad news hits and the stock crashes to $100. If the order were still active, the trader might accidentally buy a crashing stock they no longer wanted.
Key Takeaways
- A day order is valid only for the current trading session.
- If not filled by the market close (usually 4:00 PM ET), it is canceled automatically.
- It protects traders from having forgotten orders fill unexpectedly on future dates.
- Traders can specify "GTC" (Good Till Canceled) if they want an order to persist beyond one day.
- Day orders generally do not include extended hours (pre-market or after-hours) unless specified.
Day Order vs. GTC Order
The two most common time-in-force instructions.
| Feature | Day Order | GTC (Good Till Canceled) |
|---|---|---|
| Duration | Expires at market close today | Lasts until filled or canceled (often 60-90 days) |
| Maintenance | Requires re-entry daily | "Set and forget" |
| Risk | Low (no surprise fills) | Higher (market conditions may change) |
| Use Case | Active trading, intraday scalping | Long-term target buying/selling |
Extended Hours and Day Orders
A crucial nuance is that "Day" usually means "Regular Trading Hours" (9:30 AM to 4:00 PM ET). If you place a day order at 8:00 PM, it will likely be queued for the *next* morning's open, not the current after-hours session, unless you specifically select a "Day + Ext" or "All Sessions" setting. Traders must check their broker's specific definition of a "day" to avoid missing liquidity in the pre-market or after-market.
Real-World Example: Trying to Buy the Dip
A trader wants to buy Tesla (TSLA) if it dips to $200. TSLA is currently trading at $205.
FAQs
Usually, no. Most brokers define a standard "Day" order as applying only to the primary session (9:30 AM - 4:00 PM ET). You typically need to select a special time-in-force like "Day + Ext" to participate in pre-market or after-hours trading.
Yes, absolutely. You can cancel or modify a day order at any time as long as it has not yet been filled.
The order remains active in the system during the halt. If the halt lifts before the market close, the order can execute. If the stock remains halted past 4:00 PM, the order expires.
Yes, but the definition of "End of Day" varies. In forex, the day often "ends" at 5:00 PM ET (New York close). In futures, it might be the maintenance break (e.g., 5:00 PM ET for CME). Traders must know the specific session times.
Day orders force you to re-evaluate the market every morning. A GTC order placed last week might be based on a thesis that is no longer valid today. Day orders enforce discipline and prevent "stale" orders.
The Bottom Line
The day order is the bread-and-butter of active trading. By automatically expiring at the close, it provides a simple, built-in risk management tool that prevents orders from lingering in the market longer than intended. While long-term investors may prefer GTC orders for convenience, active traders rely on day orders to ensure their order book reflects only their current intent for the current session.
