The Time In Force drop down menu on Smarkets enables users to dictate the behaviour of a bet should the bet not be instantly fully matched.
The default setting means that a bet that is not fully matched would not be automatically cancelled. Any unmatched bet or unmatched portion of a bet would then be available to be cancelled by the user, or would be automatically cancelled when the market next halts.
Fill or Kill
The Fill or Kill setting allows users to avoid bets becoming partially matched. When using this setting, if a bet isn't instantly fully matched then it will be automatically cancelled. You can find a guide to using the Fill or Kill setting here.
The Keep in-play setting allows users to avoid bets being cancelled when the market is halted at the start of an event, or when a market in an event managed by Instant Match is halted by a material event. You can find our full keep in-play rules in section 10 of our betting rules. You can also find a guide to using the Keep in-play setting here.
