Continuation charts can be constructed in different ways. Data from several futures contracts has to be used, because every futures contract expires at a certain date and cannot be traded afterwards.

With the continuation settings, you can control what futures contracts (expiration months) are used for constructing the continuation chart, when the switch (rollover) between two contracts will take place, and if and how the prices of older contracts are adjusted to avoid gaps in the chart on rollover.

To change the continuation settings

▪ Right-click on the chart and select Properties.

▪ On the left side of the dialog, select the name of the chart pane, the name of the symbol and then Continuation. For example: Pane 1 > FDAX 2009H,CC > Continuation.

▪ On the right side of the dialog, adapt the default settings to your needs.

Symbol settings

With these settings, you can control what contract is used as the current contract with real prices in the continuation chart and what expiration months are used to construct the continuous contract.

Forward contract

Forward contract that is used as the current contract in the continuation chart, that means the contract that all other prices are back-adjusted to. The default setting is 1, which means that the current contract is the front month.

This setting is not connected to the rollover date in any way.

Control months

Contract expiration months that are used for creating the continuous contract. By default, all available months are included.

This setting is only available on the Continuation tab in the Symbol Search dialog. For changing the data compression later, see Changing the Data Compression.

Rollover settings

These settings control when to switch (roll over) from one contract to the next. You can either roll based on the expiration date / month of a contract, or based on its open interest / volume.
