<p>Hence, the invention is a contribution to the field of designing computer implemented systems that test how different trading algorithms work when fed historic data ('backtesting'). It teaches an efficient and effective data representation that comprises two elements. First, an object-based representation of each trading strategy; each object is instantiated as a 'strategy instance'. Secondly, a pairing between any tradable instrument and any strategy instance; the pairing is called an 'account'. A key advantage of the data representation is that the data in each account is held in a matrix format; these are easily and efficiently stored in standard relational databases. Further, operating the method involves large scale matrix operations, which are fast and computationally efficient within a matrix based language. Conventional approaches do not store data in a matrix format and hence fail to achieve the computational efficiency possible with the present invention.</p> |
