QUOTEZ
market data an agent can read and cannot act on.
An agent that can read a market can also trade it, unless the tools it is handed cannot. This server hands out prices and nothing else, and no order-placement code exists in it to be tricked into running.

A symbol that does not exist, to show what the model actually sees:
