What an exchange market is
A bookmaker sets a price and takes the other side of every bet you place. An exchange does neither. It puts up a market, lets users offer prices on both sides, and matches a back against a lay when the two agree. The exchange earns from a commission on the result rather than from you losing.
That one difference explains everything else on this page. Because another user is on the other side, you can take either role. You can be the punter who backs, or you can be the person who lays and takes the punter's stake. The five exchanges we cover on Online Cricket ID all work this way, with the ID itself issued by the desk on WhatsApp.
Backing: betting that it happens
A back bet is the one everybody already understands. You pick a selection, you stake an amount, and if the selection wins you receive your stake multiplied by the odds. If it loses, you lose the stake and nothing more.
Exchanges show odds in decimal form. At odds of 2.0, a winning bet returns twice the stake, so for every unit staked you get one unit of profit plus the unit back. At 3.0 the profit is two units per unit staked. The number already includes your stake, which trips up people who are used to fractional prices.
Laying: betting that it does not
A lay bet reverses the roles. You are now offering the price, and the backer's stake becomes your potential win. If the selection loses, you keep that stake. If it wins, you pay the backer their profit, and that payout is called your liability.
Liability is where new users get caught. Lay a selection at odds of 3.0 for a backer's stake of one unit and your liability is two units, because you owe the backer their profit of two units if the selection wins. The exchange holds that liability out of your balance the moment the bet is matched. Laying at short odds means small liability and small profit; laying at long odds means the reverse.
Know your liability before you confirm a lay
Every exchange screen shows the liability before you confirm a lay bet. Read that figure, not the stake. It is the amount that will leave your balance if the selection wins, and once matched it cannot be cancelled. If you are new to laying, keep the odds short and the stakes small until the arithmetic feels natural, and read our guide to setting your own limits before your first real session.
Session markets and the runs line
Match odds ask who wins. Session markets ask something narrower: how many runs will be scored in a defined stretch of play. It might be a single over, the first six overs of an innings, or a batter's individual score. On Indian exchanges these are often grouped under a fancy tab.
The market shows a line of runs with two sides. The yes side, sometimes labelled over or back, wins if the runs exceed the line. The no side, sometimes labelled under or lay, wins if the runs stay below it. Many screens print two adjacent numbers, one for the no side and one for the yes side, so there is no doubt about which way a result on the line itself goes. The rate shown next to each side is the odds for that side.
Session markets move fast. A boundary changes the line, and a wicket can move it further. Prices update while the ball is in the air, which is why the desk suggests watching a few overs on a demo ID before staking anything.
Worked example: one invented IPL over
This is a made-up example. The teams, the over, the line and the odds are invented to keep the maths round. Nothing here describes a real match, a real price, or the current screen of any exchange.
Suppose it is the fourteenth over of a T20 between two imaginary sides, Team A batting against Team B. The exchange opens a session market on runs in that over and shows a line with no at 8 and yes at 9. Both sides are quoted at odds of 2.0. Our imaginary user has a balance of 500 units and decides to stake 100 units.
| Bet placed | Runs off the over | Result | Balance moves by |
|---|---|---|---|
| Back yes at 9, 100 units, odds 2.0 | 12 runs | Runs beat the line, yes wins | +100 units profit, stake returned |
| Back yes at 9, 100 units, odds 2.0 | 5 runs | Runs under the line, yes loses | -100 units |
| Back no at 8, 100 units, odds 2.0 | 5 runs | Runs under the line, no wins | +100 units profit, stake returned |
| Back no at 8, 100 units, odds 2.0 | 12 runs | Runs beat the line, no loses | -100 units |
| Lay yes at 9, backer stake 100 units, odds 2.0 | 5 runs | Yes loses, layer keeps the stake | +100 units |
| Lay yes at 9, backer stake 100 units, odds 2.0 | 12 runs | Yes wins, layer pays liability | -100 units liability |
Notice that at odds of 2.0 the back and lay outcomes mirror each other exactly, which is what makes even money a good place to learn. Now change the odds. If yes had been quoted at 3.0 instead, backing yes for 100 units would return 200 units of profit on 12 runs, and laying yes for a backer's stake of 100 units would carry a liability of 200 units on the same result. The stake did not change. The liability did.
One more thing the table hides. While the over is being bowled, the 100 units staked or the liability held is locked. Our imaginary user's free balance shows 400 units until the market settles, and a withdrawal request during those six balls would be refused for the locked part. That is not a fault. It is how every exchange protects the other side of the bet.
Settlement and your balance
Settlement is the moment the exchange marks the market as decided and moves money between the two sides. For match odds that happens after the game. For a session market it can happen within minutes of the over ending, though the exact timing depends on the exchange and the desk confirms it in the chat if you ask.
Until then your balance has two parts: the free amount you can still bet or withdraw, and the held amount tied to open positions. If a payout ever looks short, check your open bets before anything else. Our guide on why a withdrawal is late covers the rest, and Deposits and Withdrawals explains how funds move in and out through the desk. When rain shortens or abandons a match, the abandoned match bets guide explains which markets settle and which are voided.
Common mistakes with back and lay in cricket betting, and how each one shows up on screen
Once the words make sense, the mistakes that remain are almost all about the screen rather than the concept. People understand that backing is betting it happens and laying is betting it does not, and then press the wrong colour anyway because the match is moving. These are the slips the desk hears about most, with the habit that prevents each.
Pressing lay when you meant back. The two prices sit side by side and the colours differ, but on a small phone in a tense over they are a thumb-width apart. The habit is to read the bet slip before confirming, every time. The slip names the selection, says back or lay, and shows the liability. If the liability looks far bigger than the stake you typed, you have laid, not backed, and you can cancel before it is matched.
Misreading liability on a lay. Laying at a high price means you are offering a large payout if the thing happens. The stake box is what you win; the liability is what you risk. New users enter the amount they are willing to lose in the stake box and are surprised by the exposure figure. A demo cricket ID is the place to make this mistake, because on play money it costs nothing and teaches the difference in one over.
Assuming a placed bet is a matched bet. An exchange bet waits for someone on the other side. An unmatched bet sits in the slip at your price and may never be taken. If the market moves away, you still have no bet. The habit is to look at the matched and unmatched columns after every placement, not just at the balance.
Confusing a session market with the match market. Runs in overs six to ten settles on those five overs alone, whatever happens to the match. People lay a session line, see the batting side collapse later, and expect to have won; the session was already decided. The cricket ID glossary has the market terms grouped so you can check what a line settles on before you touch it.
Treating the demo as optional. Everything above is learned faster by doing it once with play money than by reading it three times. Ask the desk for a demo in the same message you use to ask about an ID; the how to get online cricket ID page shows where in the chat that request fits.
Try it on a demo first
Reading about liability is one thing. Watching a runs line jump after a six is another. Every exchange we cover can be asked for a demo through the desk, and the desk confirms in the chat whether one is available right now for the exchange you name. Spend an evening with it, place pretend bets on both sides of a session line, and check the balance movement against the table above.
When you are ready for a real ID, the steps are on How to Get an Online Cricket ID. Tell the desk which exchange you want and it replies in the same chat. Terms you meet on the screen that we have not covered here are in the cricket ID glossary. Once back and lay in cricket betting make sense on paper, one demo over makes them stick.
