Cash out is the opportunity to settle your bet before the event has ended.
Some already placed bets offer you the option to cash out from the bet before the event is closed, with a different payment than original projected winnings by the bet slip, therefore you can save some winning amount or cut the losing amounts.
Cashout markets might not be available all the time on your bet, based on how the sporting event is progressing.
