Coming soon: order placement over WebSocket becomes available on September 2, 2026, on the global platform only. The EU platform is not yet supported.
Rate limits
Cancel all orders
Request parameters
One market per call — no all-markets form exists, so flattening an entire book of activity means looping over the markets in use. Passing all three trading types is safe on any market, because types that do not apply are simply not matched.
Response
The result is an empty object. No list of canceled orders comes back, and nothing matched is not an error — an empty result is indistinguishable from a market that held no orders. Re-query pending orders, or watch
Orders Pending, to confirm what was actually withdrawn.
Positions survive. This call covers resting and conditional orders on the market; an open position remains open, and only the orders protecting it are gone. Re-arm stops after a bulk cancel — see
collateral_order_tpsl_place for position-tracking protection.
Error codes
Standard transport errors and the shared account, rate-limit, and region codes are listed in Order Management.
