D2000-2 or Reuters Dealing 2000-2 was a software system designed by Reuters for foreign exchange trading.
This automated electronic trading system allowed a dealer to enter buy and/or sell prices directly into the system, thereby avoiding the need for a human broker.
The system recorded the touch price which is the highest bid and lowest ask price.
[1] The D2000-2 product superseded D2000 which was originally released in 1987 and only provided indicative foreign exchange prices.
[2] Much of the functionality of the system was incorporated in Reuters' subsequent online trading platform, Reuters 3000 Xtra.
