Welcome to the Record Formats and Messages section for DTC settlement. Here you will find technical specification documents outlining the the data format required in order to send and receive data.
Once you have set up up your batch files and messages you are ready to send your transactions for DTC settlement. Status messages will arrive as output files or messages from DTC. You may also check the status of transactions sent via file or message in the Settlement Web.
