Wall Street's major exchanges and securities firms have begun a test of how well they will be able to trade come 2000.
In total 41 organisations will link up over the next two weeks and carry out mock trades, with dates set before and after the Millennium day. This is a preliminary pilot before the full test between all of Wall Street's members next March.
The test is sponsored by the US Securities Industry Association, which claimed that its members would spend more than $5 billion on achieving Millennium system compliance.
