back-test

With it, James has been able to devise five new systems and back-test his theories against market data going back 20 years.

So I research and back-test and theorise and work on new strategies.

In 1987, they released System Writer, a software product that enabled users to develop and "back-test" their own trading ideas using historical market data.

Research it, code it, back-test it and let it fly under the direction of a master trader and system builder.
