One chart wasn't updating so I tried to use the reload function to reload just the past 5 days to see if that would help. The application decided to rewrite the entire file all the way back to the begining of the contract erasing all of the other front months.
I have a backup of the data since the last expiry, but I think using it would rewrite all of my other products too meaning I would have to reload the data since June for every instrument instead of just the one that got corrupted.
Is there any way around this?
EDIT: very oddly, this seems to have only affected the daily data for that instrument, the minute data seems to be fine.
Thank you.
