Futures and forward contracts, for example, can sometimes be rolled over instead of expiring. In this instance, the price of opening a new position will be factored into the cost. In options, rolling over an option means buying a similar option with a later expiry date.
On shorter-term trades like Spot FX, there is a cost associated with keeping the position open overnight. This can also be known as the cost of carry.
We offer forward contracts on CFDs, with rollovers available up until 15 minutes before the position is due to expire. On daily CFDs, a rollover for keeping a position overnight will be calculated differently for forex positions and other markets.
