In nest 3.13 you will have to back fill each scrip individually, by selecting scrip in MW navigating to charts, opening data table and then back filling, and doing the same for every scrip. Doing backfill for one scrip and expecting all to backfill, is not goiing to happen in Nest 3.13, another issue is 3.13 takes ages to load,
What you mention above about back filling wherein one manually back fills one scrip and all other will be done auto, is in nest 3.14 version.
Just FYI one broker has told me to move from 3.11 to higher version as they will henceforth not be giving customer support for nest 3.11, as it may be taken off anytime.
Nest is out with latest version 3.15. Can never understand Omnesys gimmickry, that they find the development of previous version obsolete so fast.
