The key instance must be attached to market reference nodes that participate in forward testing and live trading sessions, as that is the scenario in which the user must validate the account with the exchange.

Some exchanges—like Binance—require validating the user even when retrieving data from the exchange. For such reasons, the key instance must also be attached to the market reference of the sensor process instance that connects to such exchanges.

In all cases, the key instance node must reference a valid exchange account key from an account with the exchange, as defined in the Crypto Ecosystem hierarchy.

{% include important.html content="Most exchanges do not allow the same exchange account key to be used with multiple processes querying the exchange API. This means that if you are trading with multiple trading systems or multiple sessions on the same exchange, each session requires different exchange account keys." %}
