I am using "SC Data - All Services". When the symbol rolls over from ESU23-CME to ESZ23-CME, I see a large difference in historical prices. You can see the examples as well as my chart settings in the attached file. As an example, May 3rd prices for ESZ23-CME are ~50 points more than ESU23-CME. What could be the reason? |

The reason is that these are two different contracts that do not trade at the exact same prices. This is normal. But, you may want to look into the Continuous Futures Contract Chart.

As you can see from the attached chart settings, I am using "Continuous Futures Contract - Volume Based Rollover, Back Adjusted". Hence, I am expecting the month 5 data to remain identical after the rollover. |

Can it be due to the back adjustment?

Yes, the back adjustment does change the historical prices. And each past contract changes by a larger amount with each additional rollover.
