Coming soon: order placement over WebSocket becomes available on September 2, 2026, on the global platform only. The EU platform is not yet supported.
Park a margin or futures limit order outside the order book. When the market reaches activation_price, the engine places a margin limit order at price. Until then the order holds status OPEN with activated 0.

​
Rate limits

​
Place margin stop-limit order

​
Request parameters

The trigger direction is not a parameter. The engine derives activation_condition by comparing activation_price to the market at placement: above the market yields gte, below yields lte.

​
Response

The result object adds the activation fields and the position fields to the standard order object — see the order object reference. A margin stop-limit order reports type 9.
Cancel this order with order_cancel by order id. The order_cancel_conditional method applies to OCO and OTO groups only, and returns error 6 for a plain stop order. A stop-limit order also cannot be modified once it belongs to a group — see order_modify.

Error codes

Standard transport errors and the shared account, rate-limit, and region codes are listed in Order Management.
