- Back Adjustment Method- Select the method to use when calculating the back adjusted prices for the continuous contract from the drop-down list.
- Absolute Difference (default) - At rollover, the close of the base contract is compared to the next (rolling to) contract and the absolute price difference (positive or negative) is added to the historical (pre-rollover) prices of the continuous contract.
- Ratio - At rollover, the close of the base contract is compared to the next (rolling to) contract and the ratio of the two prices (rolling to/rolling from) is multiplied to the historical (pre-rollover) prices of the continuous contract.
- Unadjusted - At rollover, no price comparison or adjustment is made to compensate for price gaps that occur.
