The endpoint creates, updates, or deletes a kill-switch timer. The kill-switch acts as a safety mechanism for automated trading systems — the timer automatically cancels all open orders for the specified market if the client fails to reset the timer before expiration. Set timeout to a value between 5 and 600 (seconds) to create or update a timer. Set timeout to null to delete an existing timer.
