Database Maintenance
TXL Data maintains your ASX database regularly in order for you to have
an accurate record of currently trading securities.
Maintenance is performed on a weekly basis, with maintenance files being
published over the weekend to allow the house-keeping to be completed as a
stand-alone task.
The following actions are performed as part of database maintenance:
-
Equity prices are adjusted for changes to a company's capital base (such
as share splits, consolidations, or capital restructures)
-
De-listed securities and associated trading instruments (eg options &
warrants) are moved from the main database into a "De-listed Securities"
folder (from where you may delete them at your leisure)
-
Expired company options, warrants, exchange traded options and interest
bearing securities are delisted.
-
Securities that have undergone a name or code change are refreshed to
reflect the new name or code.
-
Securities that have traded in a deferred settlement mode (usually due to
a capital adjustment or rights issue) are merged with their original code.
-
New securities that have been added to the database during the week are
assigned their full names.
-
S&P Global Industry Classification Scheme sector lists, S&P/ASX
20/50/100/200/300 index constituents, and ASX short-sellable securities for
the Custom Folders are updately weekly.
-
New warrants and options series are assigned a clear name that reflects
their expiry date and strike price.
