Day order

Order to buy/sell a crude or product contract that expires at the trading day’s close if not filled.

A day order is an instruction to buy or sell an oil-related instrument—such as a futures contract, option, swap, or physical cargo—that is valid only for the current trading session. If the order is not executed by the market close, it automatically expires. Day orders are widely used in crude oil and refined product markets where intraday volatility can be high, particularly around data releases such as EIA inventory reports or macroeconomic announcements. Traders use day orders to control execution timing and avoid unintended exposure to overnight price risk, geopolitical headlines, or changes in Asian or European trading sessions. In physical markets, day orders may be tied to pricing windows or bid-offer negotiations that are only open for limited periods. From a risk management perspective, day orders help ensure discipline by preventing stale orders from remaining active when market conditions have changed. They are especially common among day traders, market makers, and short-term discretionary traders who rely on rapid execution and precise price levels.
