Use `outcome_side` (or `book_side`) instead. See [Order direction](/getting_started/order_direction). This field will not be removed before May 14, 2026. outcome_side: type: string enum: - 'yes' - 'no' description: > The outcome side this order is positioned for. buy-yes and sell-no produce 'yes'; buy-no and sell-yes produce 'no'. `outcome_side` describes directional exposure only; it does not change the order's price. An order at price `p` with `outcome_side=no` is matched by an order at the same price `p` with `outcome_side=yes` — both parties trade at the same price, just on opposite directions. `outcome_side` and `book_side` will become the canonical way to determine order direction. The legacy `action`, `side`, and `is_yes` fields will be deprecated in a future release — please migrate to these new fields. book_side: $ref: '#/components/schemas/BookSide' description: > Same directional bit as outcome_side in book vocabulary. 'bid' is equivalent to outcome_side 'yes'; 'ask' is equivalent to outcome_side 'no'. `outcome_side` and `book_side` will become the canonical way to determine order direction.

For event markets, this refers to the YES leg only: `bid` means buy YES, `ask` means sell YES. (Selling YES is economically equivalent to buying NO at `1 - price`, but this endpoint quotes everything from the YES side.) OrderStatus: type: string enum: - resting - canceled - executed description: The status of an order FixedPointDollars: type: string description: >- Fixed-point US dollar string. Most request fields accept 2-4 decimal places (e.g., "0.56", "0.5600"); responses emit up to 6. Valid quote intervals for a given market are constrained by that market's price level structure. example: '0.5600' FixedPointCount: type: string description: >- Fixed-point contract count string (2 decimals, e.g., "10.00"; referred to as "fp" in field names). Requests accept 0-2 decimal places (e.g., "10", "10.0", "10.00"); responses always emit 2 decimals. Fractional contract values (e.g., "2.50") are supported; the minimum granularity is 0.01 contracts. example: '10.00' SelfTradePreventionType: type: string enum: - taker_at_cross - maker description: > The self-trade prevention type for orders. `taker_at_cross` cancels the taker order when it would trade against another order from the same user; execution stops and any partial fills already matched are executed. `maker` cancels the resting maker order and continues matching.
