private/close_position

Places a reduce-only order to close an existing position. Reduce-only orders can only reduce or close a position; they cannot open a new position or increase an existing one.

You can specify whether to use a market or limit order. If using a limit order, provide the price. The order will automatically be set to reduce-only to ensure it only closes the position.
