Combining different month futures into 1 chart

[newguy05]

Hi, for futures (ie: ES mini). Usually only the front month contract are traded heavily and has useful volume. Unfortuntely it makes impossible to view a historical chart going back say 1 year. The because the futures contract expires every couple month and you can only pick 1 contract.

Is there any way to combine the contracts for historical daily chart? For example use the front month contract in the chart, until expiration date, then continue to use the next front month contract etc...

If above is confusing, the question is how do i show a daily historical chart on ES mini going back say 2 years with accurate volume information.

thanks

You can add previous front month contracts into the current front month contract using the Merge feature. More information and instructions can be found in the link below.

Merge without back adjustment?

I'd like to request the option not to back adjust data for merging into continuous contracts. It's one of those things that is technically correct but it is what most people look at that counts - and simple nearest futures with no adjustment has always been the standard.

Also if you already have your own continuous data going back years and just want to merge the current contract in, you don't want further adjustment.

NT7 has option not to back adjust.
