How Odds Work on Orbit Exchange: Back Prices, Lay Prices and Reading the Order Book (2026)
Understanding how odds are formed and displayed on Orbit Exchange is the foundation of every strategy you will use on the platform. OrbitX operates differently from any traditional bookmaker: there is no house setting prices, and what you see in the interface is a real-time auction between bettors. This guide explains exactly how exchange pricing works and how to use that knowledge to get consistently better value than any soft book.
Exchange Odds vs Bookmaker Odds: the Core Difference
At a traditional bookmaker, a pricing team or algorithm sets the odds on each outcome. Those odds are designed to ensure the bookmaker turns a profit over time regardless of results. On a standard football match, the combined implied probability of all three outcomes (home, draw, away) will typically sum to 108 to 112 percent. The excess above 100 percent is the overround, and it represents the edge extracted from you on every bet placed.
On Orbit Exchange, there is no pricing team and no overround. The exchange is a marketplace: bettors who want to back an outcome are matched against bettors who want to lay that outcome (i.e., bet it will not happen). The price is set by supply and demand. OrbitX charges a 3 percent commission on net winnings per market on the winning side only. This is how the exchange generates revenue, and it is categorically more transparent and lower-cost than a bookmaker's overround for any bettor who wins consistently.
For a Betfair refugee, this dynamic will already be familiar. OrbitX runs on the same underlying liquidity pool as Betfair, meaning the prices are structurally comparable. The key difference is that OrbitX does not charge the Betfair Premium Charge, making it the superior platform for profitable long-term bettors.

Back Price and Lay Price: Understanding the Spread
On any exchange, including Orbit Exchange, every selection has two prices displayed at any moment: the back price and the lay price.
- Back price: the best odds currently available if you want to back the selection (bet it will win). This is the price at which a layer is currently offering to take your bet.
- Lay price: the best odds at which you could lay the selection (bet it will not win). This is the price at which a backer is requesting the opposite side of the bet from you.
The back price for any selection is always lower than the lay price for the same selection at the same moment. This is the exchange spread, sometimes called the gap. If Liverpool are priced at 1.80 to back and 1.82 to lay, the spread is 2 ticks (0.02 in this price range).
When you click to back at market price on OrbitX, you are accepting the best available lay offer. When you click to lay at market price, you are accepting the best available back offer. In both cases, your bet is immediately matched against a counter-party who wanted the opposite side of the transaction at that price.
In liquid markets (Champions League group stage, Grand National, major tennis Grand Slams), the spread on Orbit Exchange is typically 1 to 3 ticks on the favourite and 2 to 6 ticks on longer-priced selections. In thin markets (League Two football, obscure Asian leagues), spreads of 20 to 50 ticks are common. A 20-tick spread at odds of 2.0 represents roughly a 1 percent cost per entry-exit round trip, which is modest. A 20-tick spread at odds of 5.0 represents closer to 2 to 3 percent per round trip, which is significant for traders. Always check the spread before entering a trading position, not just the headline price.
How the Orbit Exchange Order Book Works
The order book is the complete record of all available back and lay offers at every price level for a given selection at a given moment. Orbit Exchange displays a simplified version of the order book in the standard interface: you see the three best available back prices (from highest to lowest) and the three best available lay prices (from lowest to highest), along with the available liquidity at each level.
When you place a back bet at the best available price, you are consuming liquidity from the existing lay orders at that price. If the available liquidity at the best price is smaller than your requested stake, your bet is partially matched at the best price, with the remainder queued or matched at the next available price level.
When you place an unmatched back bet at a price better than the current best available (i.e., you want higher odds than anyone is currently offering), your request sits in the order book as a pending offer. Other bettors can see it. If the market moves to your price, or if a layer submits a new offer at your price, your bet will be matched. Unmatched bets can be cancelled at any time before matching.
| Price Level | Back Liquidity Available | Lay Liquidity Available | Notes |
|---|---|---|---|
| 1.84 | GBP 340 | - | Pending back offer in book |
| 1.82 | GBP 1,200 | - | Best available back price |
| 1.81 | GBP 680 | - | Second best back |
| Spread | Gap between best back (1.82) and best lay (1.84) = 2 ticks | ||
| 1.84 | - | GBP 2,100 | Best available lay price |
| 1.86 | - | GBP 950 | Second best lay |
| 1.88 | - | GBP 400 | Third best lay |
In the example above, if you want to back the selection and you submit a bet up to GBP 1,200, it will be matched in full at 1.82 (the best available back price). If you want to back GBP 2,000, the first GBP 1,200 is matched at 1.82 and the remaining GBP 800 is matched at 1.81. Your average matched price is slightly below 1.82.
Decimal Odds on Orbit Exchange: Quick Reference
Orbit Exchange uses decimal odds exclusively. All prices are displayed in European decimal format. Here is a reference table converting common fractional and American odds to the decimal format you will see on OrbitX:
| Decimal Odds | Fractional Equivalent | American Equivalent | Implied Probability | Profit on 100 Stake |
|---|---|---|---|---|
| 1.10 | 1/10 | -1000 | 90.9% | 10 |
| 1.25 | 1/4 | -400 | 80.0% | 25 |
| 1.50 | 1/2 | -200 | 66.7% | 50 |
| 2.00 | Evens | +100 | 50.0% | 100 |
| 2.50 | 3/2 | +150 | 40.0% | 150 |
| 3.00 | 2/1 | +200 | 33.3% | 200 |
| 4.00 | 3/1 | +300 | 25.0% | 300 |
| 5.00 | 4/1 | +400 | 20.0% | 400 |
| 6.00 | 5/1 | +500 | 16.7% | 500 |
| 10.00 | 9/1 | +900 | 10.0% | 900 |
| 20.00 | 19/1 | +1900 | 5.0% | 1,900 |
Decimal odds always include the return of your stake in the total return figure. This is a common point of confusion for bettors used to fractional odds. At fractional odds of 2/1, you win twice your stake and get your stake back, for a total return of three times your stake: that is 3.0 in decimal. The rule is: decimal odds = (fractional numerator / fractional denominator) + 1.
How Commission Affects Your Real Odds on OrbitX
Orbit Exchange charges 3 percent commission on net winnings per market. This is applied after your bets in a market are settled, not per bet. Understanding the after-commission return is essential for comparing OrbitX prices to bookmaker prices.
The formula for the after-commission return on a winning back bet is:
Net return = stake + (profit x (1 - 0.03))
So if you back at 3.0 with a GBP 100 stake, your gross profit if the bet wins is GBP 200. After 3 percent commission, the net profit is GBP 194. Your effective odds are 2.94, not 3.0.
For lay bets, commission is charged on the net winnings in the market across all bets. If you lay a selection and it loses, you collect the backer's stake. Commission is charged on that collection as your net profit for the market.
| Gross Decimal Odds | After 3% Commission | Equivalent Betfair Odds (5% commission) | Advantage vs Betfair |
|---|---|---|---|
| 2.00 | 1.97 | 1.95 | +0.02 |
| 3.00 | 2.94 | 2.90 | +0.04 |
| 5.00 | 4.88 | 4.80 | +0.08 |
| 10.00 | 9.73 | 9.55 | +0.18 |
| 20.00 | 19.43 | 19.05 | +0.38 |
At 3 percent vs Betfair's standard 5 percent commission, the difference is modest at low odds but compounds significantly over large volumes. A bettor placing GBP 50,000 per year in bets at average odds of 3.0 saves approximately GBP 1,000 in commission by using OrbitX instead of Betfair at standard rates, before any Premium Charge consideration. The Orbit Exchange commission guide explains the full commission model including market discounts and how commission compares across the major exchanges.
Getting the Best Price: Practical Strategies
There are four main approaches to improving the odds you receive on Orbit Exchange, ranked from simplest to most advanced:
1. Take the best available price immediately. For most bettors on most markets, the best available back price on the exchange will already beat any soft bookmaker price after commission. Simply accepting the displayed price is usually the right move, especially in the 60 minutes before a match when liquidity is building and the spread is tightening.
2. Queue a price. Place an unmatched back bet at higher odds than the current best available and wait for the market to reach your level. This works well in markets with predictable price drift (e.g., a heavily backed favourite shortens further as kickoff approaches, which can move money to the other selections and create better prices on the side you want). Queuing requires patience and monitoring; always set a reminder to cancel unmatched bets before in-play begins if you do not want them matched in-play.
3. Use the exchange as the sharp price reference. Check the OrbitX price before betting anywhere else. If a bookmaker offers a significantly higher price than the exchange equivalent, that divergence is worth investigating. Often it means the bookmaker's risk team has not yet adjusted and you have a genuine value opportunity at the bookmaker. This is the foundation of arbitrage betting strategy.
4. Place lay bets at the market price. When you think the market is overrating a selection, laying it at the current best available back price means you are effectively offering a fair price to the public who want to back. This is used in exchange trading strategies where you take positions on both sides of a market at different times.
The best OrbitX prices for major sports markets are typically available in the window between 30 minutes and 4 hours before the event start time. Earlier than that, market-making liquidity is present but recreational money has not yet arrived to tighten the spread. Later than that, the market is most liquid but you may encounter last-minute line moves driven by team news. For in-play betting, the highest liquidity windows are immediately after significant events (goals, red cards, first-round knockdowns) when recreational money floods in rapidly and the exchange spread briefly widens before sharp money closes it.
Accessing Orbit Exchange Odds via a Broker
Orbit Exchange is not open to the public as a direct account. Access requires registering through an authorised broker, which provides your OrbitX credentials as part of a combined account that may also include access to sharp Asian bookmakers. This structure gives you access to both the exchange price and the sharp book price simultaneously, which is the most powerful combination for any serious bettor.
The broker model does not change how the exchange odds work. Once you are logged into OrbitX through your broker account, you see the same order book, the same back and lay prices, and the same liquidity as any other OrbitX user. The broker is simply the intermediary who onboarded you and holds your wallet.
To get started, our guide to Orbit Exchange registration walks through the full account setup process, including broker selection, identity verification, and making your first deposit. For a comparison of the five main brokers that offer OrbitX access and how their commission rates and services differ, see our betting brokers guide.
If you are coming from Betfair and comparing the two platforms, the odds mechanics are nearly identical. The interface differences, commission structure, and crucially the absence of Premium Charge on OrbitX are the meaningful distinctions. Our back and lay betting guide also covers how exchange pricing fundamentals apply across all exchanges if you want to deepen your understanding beyond OrbitX-specific mechanics.
Frequently Asked Questions
Orbit Exchange uses decimal odds (also called European odds) exclusively. Decimal odds represent the total return per unit staked, including the return of the original stake. For example, decimal odds of 3.0 mean a 100 unit bet returns 300 units total (200 profit plus the 100 stake back). You cannot change the odds format on OrbitX to fractional or American; it is decimal-only throughout the interface.
The back price is the odds you receive when backing a selection to win. The lay price is the odds at which another bettor is willing to lay (offer the back bet to you). The back price is always lower than the lay price for the same selection at the same moment. The difference between them is the spread. In liquid markets (major Premier League matches), this spread is typically 2 to 5 ticks. In thin markets, it can be 20 or more ticks.
The order book shows all available back and lay offers at each price level. When you back at market price, your bet is matched against existing lay orders. When you place a lay order at a price where no back bets exist, your order sits in the book as an unmatched bet until another bettor matches it. Unmatched bets can be cancelled at any time and are typically cancelled by the exchange when the event starts if not specifically flagged as in-play bets.
A tick is the minimum price increment. On Orbit Exchange, the tick size varies by price range: between 1.01 and 2.00, the tick is 0.01; between 2.00 and 3.00, the tick is 0.02; between 3.00 and 4.00, the tick is 0.05; between 4.00 and 6.00, the tick is 0.1; between 6.00 and 10.00, the tick is 0.2; above 10.00 the tick is 0.5 or larger. This means a one-tick movement is worth proportionally more in value at lower odds than at higher odds, which affects the practical cost of the spread at different price levels.
The simplest approach is to accept the best available back price, which in a liquid market will usually already beat soft bookmaker prices after commission. For a better price, place an unmatched back bet at higher odds than currently available and wait for the market to reach your level. This is called queuing into the book. The best OrbitX prices for major sports markets tend to be available in the window 30 minutes to 4 hours before event start time.
An overround is the margin built into bookmaker odds so that the implied probabilities of all outcomes sum to more than 100 percent, guaranteeing a profit for the bookmaker over time. On Orbit Exchange, there is no overround because prices are set by supply and demand from bettors, not by a pricing team. OrbitX charges a flat 3 percent commission on net winnings per market instead. For profitable bettors, this is substantially cheaper than the combination of overround plus Premium Charge that applies on Betfair.
