Available options:
buy, sell Spot markets only — sending it on an order for any other market is rejected. Optional: omit both this and ui_intent to submit raw engine values. If either is present, this must be exactly usdc_cngn_spot_v1 and ui_intent becomes required.
Example:
"usdc_cngn_spot_v1"
Spot markets only — sending it on an order for any other market is rejected. Optional, and paired with order_entry_spec: sending one without the other is rejected. When present, the service derives side, limit_price and desired_amount from it. If you send those fields as well, each must match the translation exactly or the order is rejected.
