TR Trade Feed
The Trading session (********-TR) is used to submit and manage orders, receive execution reports, and handle fills.
OpenYield supports two models for submitting passive (resting) liquidity:
| Section | Model | Use when… |
|---|---|---|
| Equity Style Order | Equity-style limit orders via NewOrderSingle (35=D) | Your system supports standard equity-style order entry — recommended for all new integrations. |
| Fixed Income Style Quote | Fixed income-style quotes via Quote (35=S) | Your system is a legacy fixed income platform that cannot send NewOrderSingle. |
For taker (aggressive) orders, use the Equity Style Order model regardless of your system type.
The Execution section applies equally to both models. Once a passive order or quote is resting, OpenYield treats them identically — fills and cancels are reported the same way for both.
All fills and order completions are also delivered on the Drop Copy session (********-DC). See Post Trade for details. They are not documented separately here.
