Returns all currently-open orders belonging to the authenticated portfolio. Orders are returned regardless of instrument or order type; filtering by instrument kind and order type is not currently supported.

Each order includes instrument_id, product_group, and the post_only, reject_post_only, and reduce_only flags. instrument_id is the numeric instrument id. product_group is the Starbase routing group (BTC, ETH, TIER_2, or TIER_3). post_only and reject_post_only correspond to the SBE postOnly and postOnlyReject bits and are mutually exclusive. reduce_only reflects per-order reduce-only from classic JSON-RPC or FIX (it cannot be set per order in SBE).

The portfolio is resolved from the authenticated session. There is no parameter to query another portfolio's orders. MMP-flagged orders are visible via this endpoint. Orders placed via Mass Quote (MassQuoteRequest) are not currently returned.

This endpoint is rate-limited to 10 requests per minute per portfolio on each REST gateway. The A and B gateways enforce this cap independently. Exceeding the limit returns HTTP 429.
