When you make an offer on an In-Running market on BETDAQ, you can choose to "Cancel at off" or "Keep In-Running". The default option on the website is for all unmatched bets to be cancelled when the market turns 'In-Running'.
You also have the option to specify that if your bet is unmatched at the off it will be offered In-Running. This provides another chance to get the bet matched. Prior to submitting your bet select the "Keep In-Running" checkbox on the betslip.
All "Keep Bets" submitted and verified on the betslip will not be cancelled until the market closes. If the market is currently In-Running, this option is not displayed. To disable this feature go to "My Preferences" and choose to undisplay "Keep In-Running". This will remove the option from the betslip.
