Currently, this is not possible as the live score is not available from Betfair via their API. We did look at alternative sources but these provided a delayed score which is not suitable for live trading.

Websites that may help provide up to date scores can be seen below. In addition to these large tournaments often provide their own ‘live’ scoreboards. But you should be aware that this data may be subject to a time delay and/or be inaccurate. It is usually best to be watching a match live than relying on information sent over the internet. If you rely on this type of data to place bets, you do so entirely at your own risk.
