Examples of its use
Assure profits: We bet on the victory of a tennis player in a semifinal of a tournament at odds of 2.00 and our tennis player wins the first set. Having started to get on track for a possible victory, the bookmaker offers us to close the bet at that moment, but with lower profits than those implied by the 2.00 odds. The positive aspect is that we guarantee the benefits, without the need to wait for the entire match to pass, thus avoiding possibilities such as the opponent coming back from behind.
Minimize losses: In the opposite scenario, our tennis player loses the first set. At that moment, the house offers us to close the bet, recovering part of the money we have wagered. If we consider that our tennis player is not going to come back or that we have made a mistake in our analysis, it is a better option than waiting until the match is over, the defeat is consummated and we lose all our bets.
