## Session Resumption Protocol

A session resumption protocol allows a trading system to reconnect to an exchange without performing a full authentication handshake or losing the state of open orders. By using unique session identifiers or tokens, the client can resume exactly where it left off.

This minimizes downtime and ensures that active orders remain tracked and managed during brief connectivity interruptions. It is essential for high-frequency trading where every millisecond of inactivity increases exposure to market volatility.

The protocol handles the reconciliation of messages that might have been sent but not acknowledged during the disconnect. This ensures data integrity and prevents duplicate orders or missed fills.

It acts as a bridge that maintains continuity in the lifecycle of derivative contracts. Efficient session management is a hallmark of institutional-grade trading platforms.
