The new e-Watcher solution allows integration with B3 to monitor OTC trades and asset characteristics. In addition, users will be able to request asset characteristics and custody position at any time.

e-Watcher is a tool that monitors real-time transactions on B3’s OTC post-trade platform. The system sends fast and accurate updates on transactions, helping users stay up-to-date about what is happening in the market.

Unlike other solutions that need time to deliver data, e-Watcher provides data almost instantly. Messages are organized into threads and are available for query for up to 24 hours, allowing participants to access them efficiently and securely.
