Struct PolymarketOrderBuilder 

pub struct PolymarketOrderBuilder { /* private fields */ }

Builds signed Polymarket orders for submission to the CLOB V2 exchange.

last_timestamp_ms backs a strictly-monotonic millisecond clock so that bursts of submissions landing in the same wall-clock millisecond still produce distinct timestamp values (the V2 per-address uniqueness field).

Implementations

impl PolymarketOrderBuilder

pub fn new( order_signer: OrderSigner, signer_address: String, maker_address: String, signature_type: PolymarketSignatureType, ) -> Self

Creates a new PolymarketOrderBuilder.

pub fn build_limit_order( &self, token_id: &str, side: PolymarketOrderSide, price: Decimal, quantity: Decimal, order_type: PolymarketOrderType, expiration: &str, neg_risk: bool, tick_decimals: u32, ) -> Result<PolymarketOrder>

Builds and signs a limit order for submission.

Immediate BUYs spend a cent-denominated maker budget. When quantity * price is not an exact cent amount, the builder truncates that budget to cents and signs the share quantity derived from it, rounded up to the market amount precision so the signed ratio does not exceed the limit price.

expiration is a unix-seconds timestamp ("0" for non-GTD orders). It is carried in the wire body but excluded from the EIP-712 signed hash.

pub fn build_market_order( &self, token_id: &str, side: PolymarketOrderSide, price: Decimal, amount: Decimal, neg_risk: bool, tick_decimals: u32, ) -> Result<PolymarketOrder>

Builds and signs a market order for submission.

amount semantics differ by side:

• BUY: amount is pUSD to spend
• SELL: amount is shares to sell

Market orders never set an expiration.

pub fn expected_order_id( &self, order: &PolymarketOrder, neg_risk: bool, ) -> Result<VenueOrderId>

Computes the Polymarket order ID for a signed CLOB V2 order.

pub fn validate_limit_order(order: &OrderAny) -> Result<(), OrderDeniedReason>

Validates a limit order before building, returning a denial reason if invalid.

pub fn validate_market_order(order: &OrderAny) -> Result<(), OrderDeniedReason>

Validates a market order before building, returning a denial reason if invalid.
