a betting exchange trading treats sports markets like a financial exchange — you buy and sell positions on outcomes, profiting from price movements rather than needing to predict winners.
How Exchange Trading Works
On a betting exchange, every market has two sides: back (betting for) and lay (betting against). Trading exploits the gap between these prices as they move.
The core principle: Back at a higher price, then lay at a lower price. The difference is your profit.
For example, you back a football team at 3.0 (2/1) with £100. The price shortens to 2.5. You lay at 2.5 for £120. Whatever happens, you profit approximately £20 before commission.
Pre-Match Trading
Prices move before events start due to:
- Team news — a key player ruled out causes the price to drift
- Market money — large volumes of backing or laying shift prices
- Sentiment — weather changes, pitch conditions, expert tips
Pre-match traders monitor these factors and position themselves before the price moves. A typical pre-match trade lasts minutes to hours, capturing 2-10 ticks of movement.
In-Play Trading
In-play trading reacts to live events that cause price swings:
- A goal in football can move a match odds price from 2.0 to 5.0 instantly
- A break of serve in tennis swings the set winner market dramatically
- A wicket in cricket shifts the match winner odds significantly
In-play traders need fast reactions and typically use ladder interfaces that show all available prices in a vertical column for one-click execution.
Understanding Ticks and Liability
a betting exchange prices move in increments called ticks. The tick size varies by odds range:
- 1.01-2.00: ticks of 0.01 (e.g., 1.50, 1.51, 1.52)
- 2.00-3.00: ticks of 0.02
- 3.00-4.00: ticks of 0.05
- 4.00-6.00: ticks of 0.10
One tick on a £100 stake at odds of 2.00 yields approximately £1 profit. At odds of 1.50, one tick is worth roughly £0.67.
Essential Trading Software
The exchange website is too slow for serious trading. Third-party tools provide:
- Ladder interfaces — vertical price displays for rapid execution
- One-click trading — instant back and lay without confirmation
- Stop losses — automatic exit if the price moves against you
- Automation — pre-programmed strategies that execute without manual input
Getting Started
Begin with pre-match horse racing markets, which have clear price movements driven by market intelligence. Practice with minimum stakes, record every trade, and review your performance weekly. Most successful traders specialise in one or two sports rather than spreading across many.
