Finds the signed-in member’s original trade using its direction and Idempotency-Key. Requires permission to view transactions. Returns the current approval request and, once booked, the related transaction. Denied, cancelled and expired requests retain their actual status. A pending approval can include a booked transaction when its final decision is unresolved. This read never submits or retries a trade.

Use this after a timeout or duplicate-key refusal. Request-key lookups are retained for at least 24 hours; a 404 can mean that the request is still in flight or its lookup is no longer retained. It does not prove that no trade was submitted. Preserve the original key and reconcile transaction and approval history before using another key.
