Abstract

A real-time financial search engine retrieves financial updates in real-time. A condensation memory in the real-time financial search engine stores financial data in a compacted space that allows computation of a smaller set of numbers. Real-time feed is converted into a two-dimensional (X, Y) location code for placement on a linear location code array of a security symbol. A single number of a location code efficiently represents (time, price) or (time, volume) in a 2D coordinate plane for real-time search of financial data.

Claims

1. A real-time financial system, comprising:

a feed machine for receiving one or more real-time financial updates of at least one symbol; and

a real-time financial search engine, coupled to the feed machine to receive said updates and for real-time searching of the one or more real-time financial updates of the at least one symbol, the search engine including a condensation memory converting the real-time financial updates into a two-dimensional location code to construct a linear location code array, each linear location code in the linear location code array representing a pair of (X, Y) coordinates or a pair of (X, Y) coordinates, the X symbol denoting time, the Y symbol denoting price, and the Z symbol denoting volume.

2. The real-time financial search system of claim 1 wherein the condensation memory searches for the at least one symbol according to a search criteria.

3. The real-time financial search system of claim 1, further comprising a query device, coupled to the real-time financial search engine, for submitting searching parameters of the at least one symbol.

4. The real-time financial search system of claim 1, further comprising a broadcast server, coupled between the real-time financial search engine and the feed machine, for broadcasting real-time feed to the real-time financial search engine.

5. The real-time financial search system of claim 4, further comprising a real-time news search engine, coupled to the broadcast server, for searching real-time news related to the symbol.

6. The real-time financial search system of claim 4, further comprising a real-time charting and statistical analysis engine, coupled to the broadcast server, for searching real-time charting and statistics of the symbol.

7. The real-time financial search system of claim 1, further comprising a historic search engine, coupled to the broadcast server, for searching historical updates of the symbol.
