Separate intent from execution
An order request, validated order, routed order and completed trade are different states. Representing them clearly prevents confusing UI and unsafe recovery.
Market data has conditions
Freshness, entitlements, exchange rules and connection quality affect what users can see. The interface should communicate delayed or unavailable information honestly.
