What is Market Liquidity?
How Market Liquidity Works
On a betting exchange, every bet requires a counterparty: a backer needs a layer, and vice versa. Liquidity is simply the total volume of unmatched money sitting in the order book at each price. A Premier League match on a Saturday afternoon might have hundreds of thousands of pounds available on the match-odds market, meaning a £200 back bet at 2.10 can be matched almost instantly without pushing the price. A lower-league midweek cup tie might have only a few thousand pounds in the market, so the same £200 bet could move the price noticeably or be only partially matched.
Liquidity builds as an event approaches and tends to peak just before kick-off or the off. It also varies by sport, competition level, and time of day. Popular football leagues and major horse races attract far more money than niche markets. Commission rates on exchanges are applied to net winnings, typically ranging from around 2% to 5% depending on the platform and the customer's discount rate, but thin liquidity can cost you just as much by forcing you to accept a worse price than you wanted.
A Worked Example
Suppose a tipster advises backing a selection at 3.50 on an exchange. You log on and see £8,000 available at 3.50 — that is a liquid market for this event. You place £100 and it is matched in seconds at exactly the advised price. Now imagine the tipster sends the same tip for an obscure reserve-league match where only £300 is available at 3.50. Your £100 bet consumes a third of that volume, so the remaining £200 is matched at 3.40 or lower, dragging your average price down and reducing your expected return.
The difference between 3.50 and 3.40 on a £100 stake is £10 in potential returns. Across a full season of tips that shortfall compounds significantly. This is why the price at which a tipster claims to have struck their bet, and the price you can realistically achieve, can diverge sharply in illiquid markets.
Why Liquidity Matters When Judging a Tipster
When reviewing a tipster's record on TipsterCheck, it is worth checking which markets and competition levels they operate in. A tipster who consistently uses liquid top-flight football or Grade 1 racing markets gives followers a realistic chance of replicating advised odds. A tipster working in thinly traded markets — lower-league accumulators, obscure ante-post races, or niche in-play positions — may show an impressive headline yield that followers simply cannot reproduce at scale.
Proofing services can help here, but they do not always capture the practical difficulty of getting bets matched in low-liquidity markets. If a tipster advises large stakes relative to typical market volume, their own activity can move the price, making early subscribers better off than those who act even minutes later. Always consider stake size alongside liquidity: a tipster staking 2 points in a market with only a few hundred pounds available is setting a standard their followers are unlikely to meet.
Example: A tipster advises backing a selection at 3.50 on an exchange, but the market holds only £400 at that price, so a follower staking £150 partially moves the price to 3.35, costing them £2.25 in returns on that single bet alone.
FAQs
Does low liquidity affect bookmaker bets as well?
Traditional bookmakers set their own prices rather than matching bets, so liquidity in the exchange sense does not apply. However, bookmakers may limit stakes or refuse bets in obscure markets, which creates a practical equivalent problem for followers trying to replicate a tipster's advised bets.
When is liquidity typically highest on exchanges?
Liquidity usually peaks in the final minutes before an event starts and is strongest for major competitions such as top-flight football leagues, Premier League matches, or Grade 1 horse races. It builds gradually in the days beforehand and drops sharply once the event begins, though in-play markets then develop their own liquidity.
Can I check market liquidity before placing a bet?
Yes. Most exchanges display the order book, showing how much money is available at each price on both the back and lay sides. Reviewing this before placing tells you whether your stake can be matched at your target price or whether you will need to accept a worse price to get matched.
