You can use "Market conditions->Football - Bet when score" rule to bet when score is 0-0.
Also use "Market conditions->Time to bet" and set it to start betting 5 minutes after market goes in play.
Betfair does not provide live scores, so there are two ways for bot to get live score. Those are:
1. determine live score by using Correct Score market prices e.g. if Back price is higher than 500 then score is impossible. This works well only on markets with high traded volume and from most popular leagues. To use this solution just auto load Correct Score markets and bot will automatically try to determine score if possible.
2. use third party service that provides live scores and football in play statistics. You can subscribe and set up your details for this service at "Tools&Settings->General options->Football - in play statistics" tab of Bf Bot Manager V3
