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.
