Executive Summary

DN Hub is an automated tool hosted on the DRDM platform and supported by CJC's 24/7 Managed Services team. Managing Exchange data notifications (DN) manually is resource-intensive and error-prone. The DN Hub tool cross-checks Exchange usage against the latest data notifications from Exchanges worldwide and is available as either a fully managed service or a self-service option for market data teams. The tool replaces outdated, manual processes by making notification management faster and more reliable, and by providing actionable insights to its users.

Without a streamlined process to manage Exchange market data notifications, firms may face challenges that include:

  • Untracked Permission Changes.
  • Missed Fee Increases.
  • Compliance Risk Exposure.
  • Loss of Market Data.
  • Unplanned Cost Spikes.
