Historical futures contracts

[trend]

Hi,
I imported several individual contracts for aussie bonds (SFE)
from esignal, in order to build the current contract 03-10
with extended history. It worked fine (set offset and rollover dates)
Upon NT restart I realized that the historical contracts dissapeared
from the History Manager. Is sthg wrong in my settings?

Any clues?

trend,

There should be no reason why instruments would disappear unless explicitly deleted. Please go to Documents\NinjaTrader 7\db\minute or \tick, etc. to see if you can find the contract folders.

If you do not have the folders, can you please provide reproducible steps? Thank you.
