Fees, Limits, & Using the Order Book
Does ProbiFi Charge Fees?
Yes — ProbiFi applies minimal protocol fees to support long-term sustainability and reward active participants:
Trading Fee: A 0.2% fee is charged on all share buy and sell transactions within any market.
No deposit or withdrawal fees for KAS or supported tokens.
Note: Third-party services (e.g., centralized exchanges, fiat onramps) may charge network or processing fees outside of ProbiFi.
How Does ProbiFi Generate Revenue?
ProbiFi’s design allows for sustainable protocol revenue generation without compromising user experience:
Trading Fees (0.2%) A small transaction fee is applied to share trades (buys and sells), which contributes directly to protocol revenue.
Bid-Ask Spread Capture In thinner markets, trades may cross existing bid/ask spreads. ProbiFi’s internal market engine captures part of that spread, similar to traditional exchanges or AMMs.
Protocol-Owned Liquidity The protocol will allocate its own liquidity into select markets. Over time, these positions may earn profits by buying low and selling high based on outcome volatility. Revenues flow back to the NFT-based revenue-sharing system.
Sponsored & Enterprise Markets (Planned) ProbiFi aims to offer enterprise-level markets for DAOs, protocols, or real-world use cases (e.g., token governance, milestone forecasting). Partners may pay listing or liquidity fees that are routed into protocol revenue.
Are There Trading Limits?
ProbiFi’s order book is designed to be fully permissionless and uncapped — meaning there are no limits to how much you can trade at once.
That said, trading large volumes may not always be possible without affecting the market price. Liquidity is determined by the availability of counterparties — if you want to buy 10,000 YES shares and only 3,000 are listed for sale at your target price, your order will either partially fill or move the price.
Before placing large trades, it’s best to check the order book to understand:
How many buyers or sellers are currently active
At what prices they’re willing to trade
Whether the market can support your trade size without slippage
ProbiFi Order Book
The Order Book displays all active bids and asks for any given market — helping you make more informed trading decisions.
Here’s how to read it:
Green (Bids): Offers from traders looking to buy YES or NO shares, and how much they’re willing to pay
Red (Asks): Offers from traders looking to sell their shares, and the lowest price they’ll accept
The difference between the highest bid and lowest ask is called the spread
Example: In a market like “Will KAS reach $0.10 by July 2025?”, the highest bid for YES might be $0.42 and the lowest ask $0.45. The $0.03 spread tells you how tightly the market is priced — tighter spreads often indicate higher liquidity.
Market Orders vs Limit Orders
In the Market Orders guide, we covered how trades can be executed instantly at the current price.
If you're comfortable accepting the best available price, use a market order.
But if you believe the price is too high (or too low), you can place a limit order — a trade that only executes if the market reaches your target price.
Managing Your Open Orders
When you place a limit order, it will appear just below the order book on the specific market page. You can monitor its status there.
To view all of your active limit orders across all markets:
Go to your Portfolio
From there, you can track trades, cancel open orders, or adjust your exposure
Canceling Open Orders
To cancel an order:
Find your open order on the market’s page
Click the red × button beside it
Confirm cancellation in your wallet (if prompted)
All of your open orders can also be managed directly from the Portfolio tab.
