Abstract

The present invention is aimed to provide a system for providing, to a terminal device of an investor, data indicating delay of distribution of financial data, which data is used for the investor to make decisions on investment transactions in a simple and reliable way. To achieve the above aim, after entity 20 carries out specific processing of financial data received from financial data broadcasting device 10 to generate new financial data derived from the received financial data, entity 20 adds time data and an entity identifier for identifying entity 20 to the derived financial data and transmits the data to another entity 20 located at a downstream position or to financial data searching device 30.

Claims

1. A method for distributing financial data in a communication system having a data source from which financial data is transmitted, a terminal device receiving the financial data and displaying content of the financial data, and plural relays located between the data source and the terminal device for relaying the financial data, comprising:

transmitting financial data from the data source to a first relay;

adding to the financial data, at the first relay, a pair of time data indicating a current time which is obtained from an internal timer of the first relay and an entity identifier identifying the first relay;

transmitting the financial data from the first relay to a second relay or to the terminal device;

calculating, at the second relay or the terminal device which receives the financial data, a time period between a time indicated by the time data included in the financial data in a pair with the entity identifier of the first relay and a current time which is obtained from an internal timer of the second relay or the terminal device; and

determining, at the second relay or the terminal device which receives the financial data, whether critical delay of distribution of the financial data occurred at the first relay by comparing the calculated time period and a predetermined threshold time period.

2. The method for distributing financial data of claim 1, further comprising:

adding to the financial data, at the second relay which receives the financial data, a pair of time data indicating a current time which is obtained from an internal timer of the second relay and an entity identifier identifying the second relay;

transmitting the financial data from the second relay to a third relay or to the terminal device;

calculating, at the third relay or the terminal device which receives the financial data, a time period between a time indicated by the time data included in the financial data in a pair with the entity identifier of the first relay or of the second relay, and a current time which is obtained from an internal timer of the third relay or the terminal device; and

determining, at the third relay or the terminal device which receives the financial data, whether critical delay of distribution of the financial data occurred at the first relay or at the second relay by comparing the calculated time period and a predetermined threshold time period.

3. The method for distributing financial data of claim 1, further comprising:

processing, at the second relay which receives the financial data, the financial data to generate derived financial data;

adding to the derived financial data, at the second relay which receives the financial data, a pair of time data indicating a current time which is obtained from an internal timer of the second relay and an entity identifier identifying the second relay;

transmitting the derived financial data from the second relay to a third relay or to the terminal device;

calculating, at the third relay or the terminal device which receives the derived financial data, a time period between a time indicated by the time data included in the derived financial data in a pair with the entity identifier of the first relay or of the second relay, and a current time which is obtained from an internal timer of the third relay or the terminal device; and

determining, at the third relay or the terminal device which receives the derived financial data, whether critical delay of distribution of the financial data or of the derived financial data occurred at the first relay or at the second relay by comparing the calculated time period and a predetermined threshold time period.
