What is a BTTS prediction?
Both teams to score, or BTTS, is a yes-or-no market on whether both sides find the net during a match. Pick Yes and you need both home and away to score at least one goal. Pick No and you need at least one side to be kept off the scoresheet.
The market is settled on the 90 minutes plus injury time. Goals scored during extra time or penalty shootouts in cup matches do not move it. Own goals do count, because they are credited in the official match record like any other goal.
