Missing Merged data ?

[T2020]

A couple days ago I merged some ES 09-09 data with the 12-09 ES data .
It showed up on my charts and all was well . Now that data has vanished . Only the 12-09 data is there now ???

Hello T2020,

Thank you for your post.

What was the date range of the merge?
Does your data connection provide historical data in the interval you merged?

1 . ES 09-09 was 8/3/09 to 9/10/09 .

2. My data comes from TT . I think they only have a couple of weeks historical .

Hi T2020,

Thank you for your reply.

Please merge the data in to the 12-09 contract once more. After verifying that the data merged correctly, restart NinjaTrader, reconnect to TT and open a new ES 12-09 chart.
After taking these steps, does the data remain or is it overwritten once more?
