Historical Data Manager deletes data during Download

[Ralph]

Hi,

I import historical data for instruments. The imports contain data beyond the rollover date (older than the rollover date). I use the non-backadjusted merge policy with NT7.17. When I update instrument data with the HDM (Download), then the HDM deletes all historical date with a timestamp before the rollover date from the database.

NT should never delete any of my data without confirmation.

Regards

Thanks for the feedback Ralph, we'll look into here.

Ralph, can you please shed some more light on the exact scenario and setup you used (data provider, instrument, data dates present before reload, regional settings) - with ZenFire and for example ES on your non adjusted merge policy I was not seeing this happening on my end, older data was persisted if I reload the active instruments data via the HDM.
