PlayExchange – What an Exchange Is and How PlayExch Runs One

PlayExchange is simply PlayExch written out in full: Play Exchange. The longer name is a useful reminder of what the platform actually is. It is not a bookmaker that sets a price and takes every bet itself. It is a marketplace where one player's bet is matched against another player's opposite view. If you understand that one idea, the rest of the screen starts to make sense: why there are two columns of prices, why a bet can sit “unmatched”, and why you can close a position before the match ends.

This page is the technical side of PlayExch. We go through the order book, matched and partially matched bets, liquidity, why exchange odds often differ from a bookmaker's, and how cashing out by laying works, with real rupee arithmetic for each one. If you are brand new and want a plan for your first few days instead, the Play Exch first-week plan is the better starting point.

Who Is on the Other Side of Your Bet?

On an exchange, the other side of your bet is another player. When you back India to win, somebody else has laid India: they are saying India will not win, and they have put up the money to pay you if India do. PlayExch's job is to run the market, match the two sides fairly, hold the funds while the event is live and settle the result afterwards.

This is called peer-to-peer matching, and it has three practical effects:

• Prices come from players. Odds move because people are asking for and offering different prices, not because a trader decided to change them.
• You can take either side. Backing and laying are both available on almost every runner, so you can bet against an outcome as easily as for it.
• A bet needs a partner. Your bet only becomes live once someone is willing to take the opposite side at your price.

Here is an example ladder for one runner in a Match Odds market:

The figures are illustrative. Real amounts change every few seconds. What matters is how to read them, which the next section shows.

Matched, Unmatched and Partially Matched Bets

Using the ladder above, say you want to back this team for ₹2,000 at 2.20. Only ₹1,200 is waiting at 2.20. This is what happens:

1. ₹1,200 is matched at 2.20. That part is now a live bet. If the team wins, it returns ₹2,640 (a profit of ₹1,440).
2. ₹800 stays unmatched. It sits in the market as your own offer to back at 2.20, and it appears on the lay side for other players to take.
3. You choose what to do with the ₹800. You can wait for someone to match it, cancel it, or edit it to take the next price down (2.18), where ₹4,800 is available.

Until it is matched, the ₹800 is not a bet. If the result happens while it is still unmatched, it does not win or lose. That is why it is worth checking the Open Bets panel every time you place a bet. Many players assume a bet is live when part of it is still waiting.

Unmatched bets also need care when a market changes state. When a match goes in-play or a market is suspended, what happens to unmatched offers depends on that market's rules. Read the rules shown on the market before you leave an offer sitting there.

Liquidity and the Spread

Liquidity is how much money is waiting to be matched. A busy India match can have deep queues at every price. A domestic fixture or an obscure fancy line may have very little. Two things follow from that.

First, in a thin market a big stake will not be matched at the best price. It will either sit unmatched or be spread across worse prices. Second, the spread (the gap between the best back price and the best lay price) gets wider. In the ladder above the gap is one step, 2.20 to 2.22. In a quiet market it might be 2.10 to 2.40. If you back and then immediately lay in a wide market, you lose the difference.

On most exchanges, the price steps (ticks) also get bigger as the odds rise. A move from 1.50 to 1.51 is one tick. At longer odds a single tick can be a much larger jump. Keep this in mind when you set your own price and wait for a match.

Why Exchange Odds Differ from a Bookmaker's

A bookmaker builds its margin into every price. You can see the margin by turning the odds into percentages (1 ÷ odds) and adding them up. Take a two-team match priced at 1.85 each:

• 1 ÷ 1.85 = 54.1% for each team, so 108.1% in total.
• The extra 8.1% above 100% is the bookmaker's built-in edge.

On a busy exchange market, the best back prices for the same two teams might be 2.00 and 1.98: 50.0% + 50.5% = 100.5%. That is much closer to a fair book, because the prices are set by players competing with each other rather than by one house. The exchange earns its fee through commission instead, which is covered below.

The gap is largest in deep markets. In thin markets, wide spreads can wipe out the advantage, so compare the actual prices before you assume the exchange is better. If you are still unsure whether the two spellings mean the same site, our PlayExchange vs PlayExch article settles it.

Cashing Out on PlayExchange: Backing Then Laying

Because you can lay as easily as you back, you can close a position before the result is known. Exchange players call this hedging. When it leaves you with the same profit whatever happens, they call it a green book. The formula for an equal result on both outcomes is:

Lay stake = Back stake × Back price ÷ Current lay price

When the price shortens in your favour

Before the toss you back India for ₹1,000 at 2.50. India start well, and their lay price drops to 1.60. The lay stake is 1,000 × 2.50 ÷ 1.60 = ₹1,562.50, with a liability of ₹937.50.

When the price drifts against you

The same back bet, but India lose early wickets and the lay price drifts to 3.50. The lay stake is 1,000 × 2.50 ÷ 3.50 = ₹714.29. If India win: +₹1,500 − ₹1,785.71 = −₹285.71. If they do not: −₹1,000 + ₹714.29 = −₹285.71. You lock in a smaller loss instead of risking the full ₹1,000.

Both figures are before commission. Prices can move between seeing a price and confirming it, especially during an over, so check that your lay bet was fully matched. A partial match leaves you only partly hedged.

How Commission Works

On an exchange, commission is normally charged on your net winnings in a market, not on each bet and not on losing positions. If you back and lay in the same market, the bets are added together first, and commission applies only if the market as a whole ends in profit. In the green-book example above, it would apply to the ₹562.50 net profit, not to the ₹1,500 the back bet won on its own.

Rates can differ between markets and account types, so we do not quote one figure here. Check the commission rate shown in your PlayExch account, or ask our team in the chat, before you work out whether a hedge is worth placing. For a small locked profit, commission can make a noticeable difference.
