6. Market Impact Currently when executing Find Transaction through TML all transaction history is returned based on the dates provided in the FROM/THROUGH selection. With PR 900006 implementation: By default, the service will return 270 days of transaction data history at the same response time rate as today or better. An indicator will be available on Find Transaction as a control to request 4 years of data The control will allow for the return of 4 years of transaction data to be available with a potential for slower response time RMSJune 10, 2009
