A Limit Order lets you choose the exact maximum price you are willing to pay when you buy, or the minimum price you are willing to accept when you sell. Prices on Outcome are between 0.1c - 99.9c Limit Orders can:
  • Execute immediately if they cross the spread
  • Rest in the order book and provide liquidity

​
Place Orders

  1. Select Limit tab on an Event.
  2. Choose YES or NO.
  3. Enter the number of shares and your Limit Price.
  • For a Buy this is the highest price you are willing to pay.
  • For a Sell this is the lowest price you are willing to accept.
    1. Submit the order to post it on chain.

    How Limit Orders execute

    Limit Orders match against the existing order book:
    • If your buy limit is at or above the best ask
  • It immediately fills against resting asks, up to your size.
  • You never pay more than your limit price.
    • If your sell limit is at or below the best bid
  • It immediately fills against resting bids, up to your size.
  • You never receive less than your limit price.
    • If your Limit Order does not cross the best Ask/Bid it rests in the book until it is:
  • Filled by incoming Market or marketable Limit Orders
  • Manually cancelled
  • Removed when the market closes

    • ​
    Queue priority

    At each price level, orders are filled in FIFO order (first in, first out).
    • Earlier orders at a given price fill before later ones
    • This applies to both user orders and Outcome’s own quotes
    If your Limit Order is at a better price than Outcome’s quotes or entered earlier at the same price, incoming Market Orders will fill your order first.

    ​
    Complementary YES and NO

    YES and NO prices are always complementary and sum to 1 dollar at resolution.
    • Buy YES at 75¢ ($0.75) is equivalent to Sell NO at 25¢ ($0.25)
    • Sell YES at 40¢ ($0.40) is equivalent to Buy NO at 60¢ ($0.60)
    The interface shows a single side, but the order book remains consistent across both YES and NO.

    ​
    Cancel Orders

    • Navigate to Open Orders.
    • Hit Cancel next to the order you no longer want.
    • Your staked funds instantly return to your balance.
    You can cancel at any time while there is remaining size.
