What is the last trading day for Futures contracts?

The last trading day is the final day that the Futures contract may be traded before the delivery of the contract’s underlying commodity must occur. For equity index Futures like ES, it’s typically the third Friday of the contract month (e.g., June 18, 2026, for /ESM6). Commodities like Crude Oil (CL) often end a few days before the month’s close. Webull notifies users to close or roll over positions to avoid delivery or settlement issues.
