Dear Traders,
We are making slight changes to some of our automated API response messages, specifically for immediate-or-cancel (IOC) trades.
For IOC trades, they typically have to be filled immediately, or else they’re automatically canceled. On some occasions they can be only partially filled.
In the past, when orders were only partially filled, we would send an automated message notifying traders.
Going forward, this message will also include a note confirming that the remaining orders have been canceled.
This change will occur on July 24 for spot trades, and July 21 for futures trades.
To see how each API response will be changed line by line, see below – note that new changes are highlighted:
