Order direction. Use buy to open or increase a long position and sell to open or increase a short position.

Custom order identifier. Must be unique and contain only letters, numbers, dashes, dots, or underscores.
"order1987111"
When true, both legs of the OCO order can only reduce or close an existing position — neither leg can increase the position or open a new one. If the order amount exceeds the current position size, the system reduces the order to match — the response returns the adjusted amount. The API returns error code 116 if no open position exists or the order side matches the position direction. See reduce-only.
