XM offers cash CFDs which do not have an expiry date.

As CFDs are traded on margin, you will pay or receive an overnight financing rate linked to the relevant benchmark rate for the particular currency in which your position is denominated.

This means you can keep them running for as long as you choose.

For other CFDs, you can hold until the expiration dates set for each financial instrument. At the expiration of each CFD product, all open positions will be liquidated and you will need to re-open positions in order to keep trading the product.
