Requires the BROKER policy for invited users. Send quoteID and use the same tradeType/server as the saved quote; for smart quotes use executionServer. A preview without quoteID cannot be executed.

For OTC, this submits the saved quote as an offer for later filling; quote creation, offer submission and another account filling it are separate steps. Success returns a status, not a full quote. Background processing can continue after the response. Retrieve the trade to follow its status.

Expired, previously submitted or mismatched quotes can be rejected. If a request times out or its outcome is uncertain, retrieve the record before deciding what to do; repeated execution is not guaranteed safe.
