The first full version of TRAITS was released in June 2007, after a two year period of development. Since then we have been incrementally improving the system, and expanding its capacity to deal with large stock universes. With each major release we have initiated a live run with paper trades, which involves updating the system on a daily basis with live data and sending the daily trading decisions to selected third parties for inspection and validation. The entire live run process is completely automated, and trading decisions are sent out before the markets open each morning.

The following table lists the major releases of TRAITS. For more information on each release, click on the version number. For more information about live runs associated with each release, click on the live run links.
