Convert common futures and cash-market session hours from the market’s entered UTC offset into the trader’s local UTC offset.
STEP-BY-STEP
How to use this tool
- Choose the session that matches the market and data being reviewed.
- Confirm the UTC offset in effect at the market location on the planning date.
- Enter the trader’s current local UTC offset.
- Review the converted open and close plus any previous- or next-day relationship.
- Account for the Globex maintenance break where applicable.
- Verify holidays, early closes, product-specific hours, and daylight-saving changes with the exchange.
WORKED EXAMPLE
See the calculation in context
An 8:30 AM Central session with market offset −5 and trader offset −7 converts to a 6:30 AM trader-local open. Offsets must be changed when daylight-saving status changes.
Calculation method
UTC time = market-local time − market UTC offset. Trader-local time = UTC time + trader UTC offset. When a closing hour is earlier than its opening hour, it is treated as the following market calendar day.
AVOID THESE ERRORS
Common mistakes
- Using a standard-time offset during daylight-saving time
- Assuming all CME products share identical hours
- Ignoring the daily Globex maintenance break
- Using cash-session hours for overnight futures analysis
- Forgetting that converted times can fall on another calendar day
- Relying on a generic reference during exchange holidays
FREQUENTLY ASKED
Questions and answers
Why enter UTC offsets manually?
Manual offsets make the daylight-saving assumption visible and let traders convert between any locations.
Are these hours guaranteed for every product?
No. They are common presets. Product, holiday, clearing, and broker schedules can differ.
Does session open mean the best time to trade?
No. Liquidity and volatility vary by product, event risk, strategy, and market conditions.
