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.
▪ 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.

Adjustment settings
When splicing the different contracts together, you can let TeleTrader WorkStation adjust the prices of older contracts to avoid gaps in the chart. These settings control if and how the older prices are adjusted. The current contract is always shown with its real prices.
For details about price adjustment and the different options, see Back Adjustment of Continuous Contracts.
Note The adjustment settings are not used for continuation charts with weekly or monthly compression.
