Data Quality

We believe DTS's data quality is exceptional and we are reminded of this almost every day by comments from our users, who benefit from the accuracy of the data.

Our underlying data is captured at a consistent point in time, three times a day from multiple sources to coincide with the closing of each of the major world financial markets. Careful collection and screening procedures ensure that the high quality of the Horizon database is always maintained.

The data used in Horizon is regarded by our clients to be the best of breed. Not only is data collected from multiple sources but an extensive filtering and checking process is carried out by a team of dedicated Data Analysts and Researchers based in our London office.

The Collection Process

Data is collected from a range of subscription services provided by third party data vendors, brokers and highly respected market participants. Some data elements are collected in real-time, whilst other data is taken as a snapshot at different times during each trading day to match up with the three main time zones traded globally.

Initially the data is collated from the many available sources.  Next an initial investigation is carried out to reject any obvious anomalies that appear when comparing multiple values of the same instrument. The data is then subjected to rigourous manual and automated checking using a range of sophisticated analysis and investigation techniques. 

The last stage of the process involves the building of the data files used by the Horizon aplication. This data is built from the underlying data that has been collected and filtered. During this process a further filtering process is undertaken to check the data is within predetermined boundaries and conditions. Data irregularities arising here in this final stage are subject to further manual investigation before that data is available for download to Horizon’s customers.
