Place a margin or futures order priced from the best bid or offer with collateral_order_bbo_place.
Place a margin or futures limit order priced from the current best bid or offer. The role semantics match the spot order_bbo_place method, and the same ordinary limit order comes back.
The response is an ordinary margin limit order reporting type7 — no BBO marker survives placement. The price field records where the order landed. See the order object reference.
No re-pegging happens. The price is resolved once, at placement, and the order then behaves like any other resting limit order as the order book moves away from it.
