I change-over on Saturday. So set the rollover date to October 16, and set the difference in the settlement prices for Friday. That way you not have to deal with NT quirks on handling the rollover.

Also make sure that you have merge-back-adjusted set to true for CL; reload a few days data to reset the DBs and also restart your workspace so that the rolled over contract info gets loaded up.

1, Go to instrument manager and find CL.
2. Go to Edit
3. Then do tasks outlined.
You set the rollover info in the Misc Tab. You select the day at which you want to make the latest contract the current contract, and based on the settlement prices of Friday, set the adjustment values.

When you do MergeBackAdjusted it will get information about the contract value for the past from the THEN current contract. This is useful for doing Fib analysis etc.

If you select DoNotMerge or MergeWithoutAdjusting, it will either show the raw data for the current contract OR show gaps when the contract switches.

For commodities the price of futures far out is higher (think in terms of storage costs) so MergeBackAdjusted gives the best perspective about the price history.

to set the the adjustment, is this the offset where you set the rollover date or is it changing the sim feed start price.

Again great info thanks for the detail.
