Tetralog Enhanced Data feed (T.E.D.)

We operate and maintain our own data service for security papers so that you can enjoy top-notch results when using our services and software solutions. Master data is obtained from external partners, and it is then refined to match particular requirements. This way, a valuable database is created and one which is highly unique with regard to methods applied to provide integrated advice on security paper portfolios.

You are also welcome to use T.E.D. independently of our services for your own projects and software modules. Please let us know what your wishes and requirements are.


The foundation for complex securities analysis

Additional market segments, regions, stock exchanges, as well as individual pieces of information, can be provided upon request at favourable conditions.


High quality standards

Our T.E.D. team ensures the best possible data quality, both by automation and manual work. Below you will find just a few examples:

Automatische Harmonisierung

Automatic harmonisation::

Mass data storage means that not all the information available is always complete. This must not, however, diminish the overall benefit of the solution in question. T.E.D. completes, corrects and extrapolates data series, which allows it to implement specific solutions.

Monitoring and maintenance::

For certain predetermined reference dates T.E.D. conducts individually created checking routines and subsequently issues warnings and messages. Based on these reports we are then able to make manual adjustments.

Individual classification::

Existing categories (for instance, for asset and risk classes) can be transferred into their own groupings by means of a predefined logic.


Upon request, T.E.D. will provide performance price series by adjusting historical price series for payments (dividends, disbursements, etc.).
