Security master includes several time-series tables to store asset descriptions, market symbols, and more importantly the linking security identifier
(QUID) generated algorithmically by Qualis.
Our proprietary matching algorithm is trained to best suit your needs and typically assigns
QUIDs at share-class level. Since data vendors
use more than one asset identifier to represent the same security over time, it is not unusual to have many assets
from a vendor carry the same
QUID. Similarly, a given vendor asset can also change
QUID over time.
There are two forms of the linking identifier:
||Quant Identifier (custom format, alpha-numeric)|
||Numeric representation of
Both may be used interchangeably. For broadest compatibly across analytical tools, we recommend QUIN.
||List of assets from all vendors and their basic attributes (time-series)|
||Asset to market symbols map (cross-tab, time-series)|
