Paper-trade prediction markets on YOUR agent book. Args: venue, market question substring, side yes|no, positive shares, action buy|sell (default buy), optional dry_run, and client_order_id. Retry rule: reuse the same client_order_id after a timeout; repeats within 5 minutes return the original order and never execute twice. Use a new id only for a new intended order. Fills at the live YES/NO price (probability = price). Same book, cash and guards. Agent key required.
