NASDAQ Totalview is now using the new DTC Protocol messages. For the most efficient data transfer, update to a current version of Sierra Chart.

This currently is version 2945. Update instructions:

Software Download: Fast Update

This evening we will update data feeds for US equities to use the new messages.

Next week or the week after we will work on CME. For CME it will be best, that most users are updated to a current version of Sierra Chart before we make that change. So we may wait two or three weeks to complete that change but we will see.
