WSS
This stream is available on the optionsOpenOrders subscription. It provides your open orders.

Snapshot vs. Delta

The emitOptionsOpenOrders request returns a snapshot via optionsOpenOrders. Once subscribed, optionsOpenOrdersDelta messages carry incremental changes — each order includes a kind field: add for a new open order, drop when the order is no longer open (filled or cancelled).
