Post From: accessing data older than 10 years

Hi, I'm re-opening this question as I seem to be only getting exactly 10 years worth of history.

I ran some charts in March 2021 and the scid files were generated.

I then started on a fresh computer and ran exactly the same charts in Jan 2022.

What I noticed was that the data in the scid files on the fresh computer generated in Jan 2022 only seemed to go back exactly 10 years.

I then compared the scid files and found the ones generated in March 2021 had some older contracts that did not appear when I generated them in Jan 2022.

For example, the following contracts were missing for BZ (ie the ones just older than 10 years)

"BZH11-NYMEX.scid" "BZJ11-NYMEX.scid" "BZK11-NYMEX.scid" "BZM11-NYMEX.scid" "BZN11-NYMEX.scid" "BZQ11-NYMEX.scid" "BZU11-NYMEX.scid" "BZV11-NYMEX.scid" "BZX11-NYMEX.scid" "BZZ11-NYMEX.scid"

In the chart settings, I have 'number of days to load' = 7300, which should give me comfortably more than 10 years.

I also noted the format of the scid files (the date is now a 64 bit integer) on the new computer is different as it had the latest version of sierra chart, so it's not as simple as just copying them over (my old computer has died, but I made a copy of the files).

Hence it seems that if I start from scratch, I can't replicate what I had.

Is there something that I can do to get all the data generated rather than what appears like a limit of exactly 10 years? It's not much more than what exists (according to your doco on stored history), but it is important.

Thanks in advance.
