this standard is for exchanges,brokers,dealers,execution venues to implement, providing a standard universal and consistant MCP for agent trading.

agents trading with other agents is not in scope here nor the purpose of this specification. though it is an interesting idea for a different project, for sure.

main idea here is for brokers, exchanges, execution venues to all implement the same APEX specification for MCP trading. This allows agents to have a common universal interface across all systems instead of fragmented bespoke integrations sprinkled everywhere.

its not a competitor to FIX, it is an agent MCP based "sister" protocol. they serve different purposes.
