Hello alexstox,

I would check each one to see the rollover dates for each one as they may be different. You may view the rollover dates inside of NinjaTrader by going to Tools -> Instrument Manager, then type the name of the instrument inside of the Name field, press Search, select the instrument you would like to view, press the Edit button below, select the Misc tab up at the top, then scroll down to the bottom to the Contract Months and press the "..." ellipse button to view it.

Hello alexstox,

Thanks for your reply.

Upon further review of your charts I am able to see that you are using the setting MergeBackAdjusted. With this settings the past data will be adjusted so there are no gaps between rollovers.
To have the data show the actual value within the Control Center go to Tools> Options Data
Set the Merge Policy to MergeNonBackAdjusted
Select OK
Right click on your chart and select Reload All Historical Data

Eureka! Now I really understood what is "merge back adjusted" and "non-ba"!!!
But still have one question.
Why "merge ba" set as default in NT? Because of easy use for script systems?
As trader, I prefer "non-ba" as it shows real history price.

Hello alexstox,

Thanks for your reply.

That is correct, many people use the merge back adjusted setting so that backtesting and indicators calculate smoothly across multiple contracts.
