错误响应

下单和撤单错误通常以与批量请求长度相同的向量形式返回。

以下是可能的批量错误响应列表：

错误来源	错误类型	错误字符串
Order	Tick	Price must be divisible by tick size.
Order	MinTradeNtl	Order must have minimum value of $10.
Order	MinTradeSpotNtl	Order must have minimum value of 10 {quote_token}.
Order	PerpMargin	Insufficient margin to place order.
Order	ReduceOnly	Reduce only order would increase position.
Order	BadAloPx	Post only order would have immediately matched, bbo was {bbo}.
Order	IocCancel	Order could not immediately match against any resting orders.
Order	BadTriggerPx	Invalid TP/SL price.
Order	MarketOrderNoLiquidity	No liquidity available for market order.
Order	PositionIncreaseAtOpenInterestCap	Order would increase open interest while open interest is capped
Order	PositionFlipAtOpenInterestCap	Order would increase open interest while open interest is capped
Order	TooAggressiveAtOpenInterestCap	Order rejected due to price more aggressive than oracle while at open interest cap
Order	OpenInterestIncrease	Order would increase open interest too quickly
Order	InsufficientSpotBalance	(Spot-only) Order has insufficient spot balance to trade
Order	Oracle	Order price too far from oracle
Order	PerpMaxPosition	Order would cause position to exceed margin tier limit at current leverage
Cancel	MissingOrder	Order was never placed, already canceled, or filled.

重要提示：某些错误是负载本身的确定性函数，这些错误会作为预校验（pre-validation）的一部分提前返回。在这种情况下，整个负载只返回一个错误，因为其中一些错误并不针对特定的订单或撤单。

示例包括：空的订单批量、非只减仓（reduce-only）的 TP/SL 订单、订单价格偏离参考价过大，以及某些形式的 tick size 校验。

对于使用批量处理的 API 用户，建议处理一个批量多笔订单只返回单个错误的情况。此时，该响应可以在被送入回调函数之前复制 n 份，因为整个批量都是因同一原因被拒绝的。

对于使用历史订单的 API 用户，所有撤单/拒绝历史订单状态的列表可在这里查看。
