A betting exchange is a market where bettors set the prices and bet against each other. Back a team to win. Lay it to bet against it. The exchange matches both sides and charges commission on a winning position instead of building a bookmaker's margin into every price.
OrbitX gives AsianConnect88 clients this Betfair-powered model with back and lay markets, live trading and a flat 3% commission on net winnings from a winning position. The screen may look unfamiliar for five minutes. The logic is simple: choose your side, choose your price and choose your stake.
What a betting exchange actually is
A betting exchange is a peer-to-peer marketplace. You do not bet against the house. You bet against another person who disagrees with you. The exchange sits in the middle, matches the two of you, and takes a small commission from whoever wins. That is the entire business model.
Compare this to a traditional bookmaker. When you place a bet with bet365 or William Hill, you are not betting against other punters. You are betting against the company. If you win, they lose. This is why they restrict winners, limit accounts, and offer odds that are worse than the true probability of the event. The margin is baked into every price. You pay it whether you win or lose, because the odds you accepted were never fair to begin with.
| Dimension | Traditional Bookmaker | Betting Exchange |
|---|---|---|
| Counterparty | You vs the bookmaker | You vs another bettor |
| Who sets odds | In-house traders | Supply and demand |
| Revenue model | Margin baked into odds | 3% commission on OrbitX winning positions |
| Winner restrictions | Aggressive limiting | None (winners welcome) |
| Lay betting | Not available | Core feature |
| Pre-commission overround | 104-112% | 101-103% |
The last row is the one that should hold your attention. A 101% overround is close to a fair book. At 112%, the overround excess is 12 percentage points, but that does not mean 12 pence is lost from every pound. Under a proportional-margin model, the implied payout rate is 1 / 1.12, or roughly 89.3%, which corresponds to about 10.7% expected price drag. Tighter market-driven pricing matters over volume.
Backing and laying: the only two moves that exist
On a traditional bookmaker, you have one option: back something to win. On an exchange, you have two.
Backing (the blue button) is the standard bet. You pick an outcome and stake money on it happening. If it wins, you profit. If it loses, you lose your stake. You already know this.
Laying (the pink button) is the opposite. You bet that something will not happen. You are acting as the bookmaker. Someone else backs a horse at 6.0 with 10 GBP, and you take the other side. If the horse loses, you keep their 10 GBP. If the horse wins, you pay them 50 GBP. Your liability is 50 GBP. That is the number that matters: stake x (odds - 1). Not the 10 GBP stake. The 50 GBP you stand to lose.
New exchange users confuse the lay stake with their own exposure and get wiped out within a week. This is a common mistake among new exchange users. Single-exposure on a lay bet should be capped at 1-2% of your bankroll. Treat the liability as the real stake, because it is.
This dual ability (backing and laying) is what enables trading. You can open a position when odds are high, then close it when they drop, locking in profit regardless of who wins. More on that shortly.
The math: why lower costs preserve more of your edge
Here is the comparison. Take a bettor placing 500 bets of 100€ each. Total turnover: 50.000€. We will look at two separate scenarios: first, the raw cost of the margin for a flat bettor. Second, what happens when a bettor with a genuine edge bets into those same prices.
Scenario A: The structural cost for any bettor
If sharp pricing averages 1.8% overround while a retail alternative prices the same market at 7.5% overround, the difference in expected margin drag is stark. This is what the pricing structure extracts before any skill enters the equation:
Sharp pricing (1.8% overround): 50.000€ × (1 − 1/1.018) = 884€ expected pricing drag.
Retail pricing (7.5% overround): 50.000€ × (1 − 1/1.075) = 3.488€ expected pricing drag.
Difference: 2.604€ per season. That is the structural gap between the two pricing environments before a single pick is made.
Scenario B: What happens with a genuine edge
Now take a bettor with a +3% edge over fair odds. This worked example assumes fair odds of 2.00, a true win probability of 51.5%, and margin applied uniformly across outcomes. At each venue, the offered odds and expected returns look like this:
Sharp pricing (1.8% overround): The fair 2.00 becomes 2.00 / 1.018 ≈ 1.9646 on screen. Expected ROI: 0.515 × 1.9646 − 1 ≈ +1.18%. Over 500 bets of 100€: approximately +589€ per year.
Retail pricing (7.5% overround): The fair 2.00 becomes 2.00 / 1.075 ≈ 1.8605 on screen. Expected ROI: 0.515 × 1.8605 − 1 ≈ −4.19%. Over 500 bets: approximately −2.093€ per year.
The difference is roughly 2.682€ per season. The bettor's picks are identical. The strike rate is identical. The venue choice alone determines whether the edge compounds or is consumed by the pricing structure.
| Venue | Example Margin | Offered Odds (fair 2.00) | Expected Annual Result (50.000€ turnover, 51.5% win rate) |
|---|---|---|---|
| Retail bookmaker | 7.5% overround | ~1.8605 | −2.093€ |
| Sharp-pricing example | 1.8% overround | ~1.9646 | +589€ |
The profit swing from retail pricing to sharp pricing: roughly 2.682€ per season for a bettor with a +3% edge. Over thousands of bets, this compounds into the difference between a profitable track record and a structural loss. Same picks. Same strike rate. Different venue.
Retail bookmaker (7.5% overround): −2.093€ per year. Edge consumed by pricing structure. Sharp-pricing swing: 2.682€.
Where the exchange fits
OrbitX operates as an exchange rather than a traditional bookmaker. It charges a flat 3% commission on net winnings from a winning position, while market activity sets the prices instead of a bookmaker's fixed margin schedule.
For a bettor with a consistent edge, a low commission rate can preserve more of each winning market result than a retail pricing model that builds margin into every price. OrbitX is a Betfair-powered white-label exchange with back-and-lay betting, live trading, strong liquidity on major events and broad market access. Supply and demand set the prices. For price-sensitive bettors, that combination of low commission and market-driven pricing is a strong fit.

Your final return still depends on your strike rate, prices and trading decisions. OrbitX keeps its side simple: a transparent 3% commission on net winnings from a winning position, with no bookmaker margin built into every price.
In-play trading: lock in profit before the event is over
This is the exchange's killer feature. On a traditional bookmaker, once you place a bet, you wait. On an exchange, you can close your position mid-event by taking the opposite side of your own bet.
Here is a concrete example from a tennis match, which is where this strategy works best because odds move violently on every point.
Djokovic is playing Sinner. Pre-match, Djokovic is the favourite at 1.60. The match starts. Djokovic loses his serve early in the first set. The market panics. His odds spike to 2.50.
Step 1: Back at 2.50. You back Djokovic for 100 GBP at 2.50. If he wins, gross profit is 150 GBP. If he loses, you lose 100 GBP.
Step 2: Djokovic breaks back. He settles into the match. His odds drop to 1.80. The panic was an overreaction, exactly what you expected.
Step 3: Lay at 1.80. You lay Djokovic for 138.89 GBP at 1.80. This is calculated as: (100 x 2.50) / 1.80 = 138.89.
Step 4: You are done. Whatever happens now, you profit. Here is the green book:
| Outcome | Back Result | Lay Result | Gross Profit |
|---|---|---|---|
| Djokovic wins | +150.00 GBP | -111.11 GBP | +38.89 GBP |
| Djokovic loses | -100.00 GBP | +138.89 GBP | +38.89 GBP |
The gross profit of 38.89 GBP is the same either way. OrbitX's 3% commission reduces that to roughly 37.72 GBP. The basic formula gives you a balanced book before commission:
Lay stake = (Back stake × Back odds) / Lay odds
To finish with exactly the same net return on both outcomes, include the 3% commission when setting the lay stake. OrbitX displays the liability before confirmation, so you can see the exposure before placing the trade.
The key entry points for this strategy in tennis: break point against the favourite, favourite loses the first set, favourite loses serve early, injury scare or medical timeout. All four produce the same pattern: a temporary odds spike driven by fear rather than fundamentals. The market overreacts. You buy the dip and sell the recovery.
Set your own odds: become the market maker
On an exchange, you never have to accept the listed price. You can name your own and wait to get matched.
If the current market shows Back: 3.65 | Lay: 3.80, you could offer to lay at 3.70. That is better (lower) than the current best lay price of 3.80, which makes your offer more attractive to backers. Your offer sits in the queue until someone accepts it. You are undercutting existing layers and tightening the spread.
By offering to lay at 3.70 when the back price is 3.65, you create a spread of just 0.05. In a liquid market, that can be more competitive than accepting a fixed bookmaker quote. Backers get a better price than the current 3.65 back. You get a better lay price than the current 3.80 lay. The exchange facilitates the match and charges its commission when the position wins.
The tick increments on Betfair (and therefore OrbitX) are worth memorising:
| Odds Range | Tick Size |
|---|---|
| 1.01 - 2.00 | 0.01 |
| 2.00 - 3.00 | 0.02 |
| 3.00 - 4.00 | 0.05 |
| 4.00 - 6.00 | 0.10 |
| 6.00 - 10.00 | 0.20 |
| 10.00 - 20.00 | 0.50 |
If you try to lay at a price that is better than what is already available, Betfair's matching algorithm may fill you at an even better price than you requested if there is a backer waiting at a higher price. The system is designed to give both sides the best available rate. That is the opposite of how a bookmaker operates.
When to use an exchange vs when to use a sharp bookmaker
This is not an either/or decision. Both products serve different purposes. The question is when to use each.
Use an exchange when: liquidity is strongest near the event, you want to lay a selection, you are trading in-play, you have been restricted by traditional bookmakers, or you want prices formed directly by the market.
Use a sharp bookmaker (Pinnacle/PS3838) when: markets are still forming before exchange liquidity builds, you are betting a minor league or niche market, you prefer fixed-odds execution, or your strategy depends on a deeper pre-match menu.
Use a traditional bookmaker when: you have active promotions (Best Odds Guaranteed, enhanced place terms, free bets), you want accumulators or bet builders (these barely exist on exchanges), or you are betting casually at low volume where bonuses matter more than marginal pricing differences.
For many major events, the morning is a useful comparison window. Exchange liquidity is building, sharp sportsbook prices are maturing and promotional books may still offer BOG. In the final minutes before the event, liquid exchange prices can become highly competitive, but the market has also absorbed more information. Compare the available price, commission and liquidity rather than assuming one venue always leads.
Common mistakes that cost new exchange users money
Not accounting for commission in profit calculations. A 100 GBP stake at odds of 3.0 produces 200 GBP gross profit. After 3% commission, the net profit is 194 GBP. The yield is 194%, because the commission applies to the 200 GBP profit rather than the 100 GBP stake.
Commission stacking across multiple markets. Commission is calculated per market, not per session. A trader who wins 2,075 GBP in one market and loses 2,024 GBP in another is 51 GBP ahead before commission. At OrbitX's 3% rate, the winning market carries 62.25 GBP commission, leaving an overall net loss of 11.25 GBP. Track each market separately.
Laying without calculating liability. Laying 100 GBP at odds of 5.0 exposes you to 400 GBP liability. The lay stake is not your exposure. The formula is the exposure.
Trading illiquid markets. Placing orders in thin markets means partial fills at worse prices. If the market does not have matched volume behind the displayed odds, you will not get filled at that price. Always check matched volume before placing orders. The cross-over point, per academic research, is about 23,400 GBP cumulative trading volume: below that, bookmakers offer better effective prices.
Over-trading. More trades equal more exposure to risk, slippage, and commission. Trading too frequently in low-liquidity markets compounds costs. Quality over quantity. Every trade should have a reason that exists independent of the fact that you can make it.
OrbitX specifics: what you need to know
OrbitX is available through AsianConnect88 rather than direct registration. Its browser-based interface works on desktop and mobile, keeping back, lay and live-trading markets inside the same broker account. The standard commission is 3% on net winnings from a winning position, with maximum exposure of approximately 3.000€.
Liquidity is strongest on major events: Premier League football, the Champions League, Grand Slam tennis, UK and Irish horse racing, and major cricket. As with every exchange, smaller markets can carry less money at each price, so check matched volume before placing a larger trade.
AsianConnect88 handles verification, deposits and withdrawals for the OrbitX account. Completing KYC early keeps the account ready and lets you focus on the exchange once you want to fund or withdraw.
For a closer look at the product itself, the full OrbitX review walks through its desktop and mobile trading screens, back-and-lay markets, and access through AsianConnect88.
The bottom line
OrbitX earns its place when you want more control than a fixed-odds bet allows. Back when the price is attractive, lay to oppose an outcome, or trade out as the market moves. Its 3% commission is clear, and its market-driven prices reward disciplined execution.
An exchange does not create your edge. It gives that edge room to work. OrbitX combines Betfair-powered exchange markets, a competitive 3% commission and convenient access through AsianConnect88. For bettors who want to back, lay and trade from one account, that is a persuasive alternative to retail pricing.
