Trading Hours and Holiday Calendar
Trading Hours
Markets trade electronically, opening at 1800 U.S. Eastern Standard Time (EST) and closing at 1715 EST the next day, Sundays through Fridays - the same as the NYMEX trading hours. Singapore is 13 hours ahead of EST and Dubai is 9 hours ahead. The time difference is reduced by one hour when Daylight Saving Time is in effect in the U.S. Neither Dubai nor Singapore observe Daylight Saving Time.
Settlement
A daily Oman OSP settlement price is published by the DME for the front month DME Oman Crude Oil Futures Contract at 1630 Singapore time.
The DME also publishes an end of day settlement price at 1430 EST for all contracts. This timing coincides with the settlement prices of the NYMEX light sweet crude oil futures contract and other key energy markets. The DME end of day settlement price is used by the Clearing House to mark to market open positions and thereby establish variation margin.
The DME is closed for trading on New Year's Day, Good Friday and Christmas Day, therefore no settlement prices will be published on these days. As illustrated in the table below, there are six additional US holidays where no margining will occur, but there will be a daily Oman OSP settlement price published for the DME Oman Crude Oil Futures Contract at 1630 Singapore time on these days.
