tennis stopped
Betfair imposes a 5-sec delay on all bets placed on in-play tennis markets and if your cashing out on the Betfair website to slow refresh speed will also mean the prices will have moved between submitting the order and the time it eventually arrives in the market.
If use the ladder screen in Bet Angel to cashout (green up) you will have faster refresh rates and also be able to click a green up figure outside the current price, increasing the chances of it being matched
