Summon with a Limit and Fill

Send a Summon with a limit (537=1 and a price, 44) on the RQ session. OpenYield acknowledges receipt and, 5 seconds after the request, places your price on the marketplace as a limit order. A Summon (537=0), or 537=1 without a price, places no order.

Two acknowledgments arrive on RQ in sequence:

• A pending acknowledgment (OrdStatus 39=A), on a staged OrderID (SD), signals that OpenYield received the request.
• A new acknowledgment (39=0), on a live OrderID (OD), signals that the limit is now on the marketplace.

Once live, fills arrive on TR and DC as contra-side liquidity is matched. When the order is completely filled, the final fill (OrdStatus 39=2) gives the total quantity and average price and closes the order.
