## What Is In-Play Betting?

In-play betting — also called live betting or in-running trading — lets you place bets after a sporting event has already started. As the match progresses, odds shift to reflect the current state of play: a goal changes football odds instantly; a break of serve moves tennis prices dramatically.

On a betting exchange, in-play markets let you do more than just bet — you can trade. Open a position early in the match, and close it (by laying at longer odds or backing at shorter odds) once the price has moved in your favour. This locks in a profit regardless of the final result.

| <p>▶ Example: Football in-play trade</p><p>You back the underdog at 4.0 (3/1) before kick-off. They score first. Odds compress to 1.8. You lay them at 1.8 to close the trade — locking in profit on all outcomes before half-time.</p> |

### Why BetDEX for In-Play Trading

#### Speed

BetDEX is built for the Bettor and finalises transactions in under a second. For in-play markets where odds can shift in moments — a corner kick, a yellow card, a missed penalty — transaction speed is critical. Slow platform latency means orders execute at stale prices.

#### No Stake Limits

Traditional platforms restrict winning in-play traders. BetDEX has no stake limits, meaning you can trade larger positions as your edge and confidence grow — without the platform penalising your success.

### In-Play Trading Strategies on BetDEX

* Back-to-lay (pre/in-play): Back a favourite pre-match, then lay at shorter odds when they go ahead in-play.
* Lay the draw: Lay the draw pre-match in football. When a goal is scored, the draw price drifts — close by backing the draw at longer odds for a profit.
* Momentum trading in tennis: Tennis odds fluctuate dramatically between games and sets, creating consistent short-term trading opportunities.
* Scoreline arbitrage: After a goal, rapidly assess whether new prices reflect true probability and trade accordingly.<br>
