Order Types

All orders are matched using price-time priority. At the same price level, earlier orders fill first.

• Market orders: The user chooses the amount to trade and his order is completely filled at the best prices the orderbook is offering.

• Limit Orders: The user chooses the amount to trade and the price to trade at. Based on the type of limit order, different behaviors are possible:

  • Standard: The amount is filled until the chosen price. The unfilled amount is placed as a pending order on the orderbook.

  • Fill Or Kill: The order needs to be completely filled until the price, otherwise the transaction aborts.

  • Post Only: Ensures the order is placed on the book with no fills. If the order would immediately match against existing liquidity, the transaction aborts. Use this to guarantee maker fees.

  • Immediate Or Cancel: The order is filled until the chosen price, the unfilled amount is canceled and returned to the account.

• Stop Market Order: Triggers a market order when the mark price crosses your stop price.

• Stop Limit Order: Triggers a limit order when the mark price crosses your stop price.
