Wrong chart data

[ZeFs1]

I open chart ZW-03-12, but i see same picture as ZW-12-11. In realtime Ask and Bid - right, but history is wrong. For example if i will open chart at the half of session, i will see last candle - right ZW-03-12 price, and all others - copy of ZW-12-11. This happens on intraday charts. I use 2 min chart.

Hello ZeFs1,

Thank you for your post.

This is due to the merge policy settings in NinjaTrader and the December contract still actively trading.

You can avoid this issue by going to Tools--> Instrument Manager--> Locate the ZW instrument and select "Edit".

From the Instrument Editor, locate the Merge Policy settings and set this to "DoNotMerge". You should then see the ZW 03-12 contract with the correct last price, rather than back adjusted to match the current prices of the 12-11 Contract.

You can read more about Understanding Merge Policy settings from the following link:

Please let me know if there is anything else I can do for you.
