Derivatives Trading Interface Error Messages

Market is suspended; trading is unavailable.

An inactive derivatives market was specified in the order submission request.

Price is smaller or equal to zero, price exceeds the max price set for the contract, or price is not a multiple of the tick size. This is also returned if a trigger order’s trigger settings are invalid.

Quantity decimals are greater than the contract value trade precision, notional size exceeds the order max volume of 20,000,000 USD, or quantity specified is less than zero.

Notional size is lower than the small order threshold of 0.01 USD.

Incremental initial margin is greater than the usable margin.

Incremental initial margin = new initial margin with orders - initial margin with orders + effective fee - min(PNL after execution, 0)

Max maintenance margin impact = max(maintenance margin after execution - maintenance margin, 0)

Usable margin = if(max maintenance margin impact = 0, margin equity - initial margin with orders, margin equity - maintenance margin)

Order would fill at a worse price than the mark price, causing the portfolio value to fall below the maintenance margin and trigger a liquidation.

Client order ID specified currently being used in an open order.

Client order ID specified exceeds the max character length of 100.

The sum of the max position size, existing orders size, and order quantity would exceed the max position size set for the contract. This is also returned if the order would push the contract’s total open interest above its limit, or your share of the contract’s open interest above the per-user limit.

Taker order would fill 20% away from the mark price.

Taker order would cause the contract price to deviate from the index in the direction specified as the price dislocation direction for that contract.

The requested changes would not cause any modifications to the order. This is also returned if an earlier edit to the same order is still being held by maker protection. The order is left unchanged.

The order ID could not be found in the account open orders.

The order ID could not be found in the account open orders.

The order is not a trigger order and the edit order request contains a stop price.

The order or the market is set to post-only and the order would be filled upon placement. If the market is in post-only orders cannot cross the mark price.

The immediate-or-cancel order would not execute immediately. This also applies to an order held by maker protection that could not trade when it was released.

A fill-or-kill order could not be filled in full against the order book, so none of it was executed.

The taker order would match with a maker order belonging to the same account.

The account or contract is set to reduce-only, the current position size is equal to zero, the position is long and the order is a reduce-only buy, or the position is short and the order is a reduce-only sell.

An edit to an order held by maker protection was partly filled when released, and the rest of the order was refused because it could not rest on the book.

The market is set to post-only mode. Unused. Refer to POST_WOULD_EXECUTE.

The order was refused for one of two reasons:

• Open order limit: your open orders and order triggers on this account would exceed 20,000.
• Maker protection hold limit: on markets with maker protection, you can only have a limited number of orders held at the same time (currently 500). The limit is shared between a master account and all of its subaccounts. Post-only orders are never held, so they don’t count towards it. A refused order never reached the order book, so you can safely send it again once your earlier held orders are released (within 100 ms).

See Maker protection: how many orders you can have held at once.

The incremental initial margin would go below the margin schedule threshold.

Client order ID is not ASCII printable.

The order request attempts to edit the trigger price of a trailing stop order.

The contract was repeated while checking margin for multiple orders.

The order’s processing deadline had passed before it could be processed. This includes:

• a deadline that is shorter than the maker-protection hold
• an order held by maker protection that was removed before release, for example during a liquidation, de-risking or an admin cancel-all

A closing order failed the margin check. See INSUFFICIENT_MARGIN.
