Market/Limit Orders
How Limit Orders Work on ProbiFi
Looking to trade on your own terms? ProbiFi supports limit orders, allowing you to set the exact price you're willing to pay (or receive) for YES or NO shares in any market.
This guide covers what limit orders are, how they work, how to manage them, and where to find them in the dApp.
What Is a Limit Order?
A limit order is a trade that only executes when the market reaches your target price.
Let’s say you're looking at a market like “Will KAS reach $0.10 by July 2025?” The current YES share is priced at $0.73, but you’re only willing to buy if the price drops to $0.72. Instead of buying at market, you can place a limit order at $0.72. If another trader is willing to sell at that price, your order fills automatically.
Limit orders can partially fill depending on market volume
Unfilled portions remain in the Order Book until matched or cancelled
How to Place a Limit Order
Go to any live market on ProbiFi
Choose YES or NO, then click Advanced Options
Enter your desired price (e.g., $0.65)
Specify the amount you'd like to buy or sell
Once submitted, your order will appear just below the market’s live order book.
Managing Your Open Orders
You can view and manage all open limit orders directly on the market page, just below the order book.
To view your full list of pending trades across all markets, go to the Portfolio page.
If you’ve placed limit orders in time-sensitive markets (like sports or elections), note:
In sports markets, all open limit orders are automatically canceled at the start of the event (e.g., at kickoff or first pitch)
Some markets may include a short delay (e.g., 3 seconds) on marketable orders to prevent last-second manipulation
Canceling a Limit Order
To cancel an open order:
Go to the market where the order is placed
Find your open order under the order book
Click the red "×" button next to the order
Confirm the cancellation in your wallet (if prompted)
You can also cancel or edit open orders from the Portfolio at any time.

What Is a Market Order?
A market order executes immediately at the best price currently available in the Order Book. It’s ideal when you want to get into a position quickly and don’t mind a small difference in price.
Example: If the lowest ask for YES shares is $0.47, placing a market order to buy YES will fill at that price, assuming enough liquidity is available.
Unlike limit orders, you won’t need to wait for a matching order — the trade executes as soon as you confirm it.

Tips for Using Market Orders
Use market orders for fast entry into highly liquid markets
In low-liquidity markets, large market orders may fill at a higher or lower average price due to slippage
For more precise control over price, consider using Limit Orders
