Rollover is the transition of the underlying instrument from an expiring contract to a longer-term feasible contract.
Since some instruments offered by SwissMain.com are based on futures contracts and do not have a specific maturity, they have to be periodically rolled. The benefit of this is that the client can keep positions open longer by switching to another contract.
The table values represent the date of the rollover. For instance: 12th February means that contracts will be rolled at midnight on 12/13th February (swap points will be calculated at that moment)
