When you are trading crude oil CFD futures contracts on the MT4 platform, if you hold a position over the monthly expiration date of the futures contracts, there will be a CFD rollover.

To avoid CFD rollovers, clients can choose to close any open CFD positions prior to the expiration date.
As crude oil (CL-Oil) futures contracts will have an expiration date, kindly note that positions that are open on the expiration date will be adjusted via a rollover charge or credited to reflect the price difference between the expiring and new contracts.
