According to the winning odds, the discount is divided into low, medium and high, that is, low water, medium water and high water. The subdivision of the three water levels can also be divided into: ultra-low water, low water, medium-low water, medium water, medium-high water, high water and ultra-high water. Take the semi-ball in Macau as an example. If Team A makes Team B semi-ball, if the winning discount of Team A is 0.80 and the winning discount of Team B is 1.04, then Team A is the low water side and Team B is the high water side. As mentioned earlier, the Asian plate will be adjusted due to changes in funds and information, and the Asian plate has more adjustment means than the European plate. In addition to the lifting plate, the dealer can also control risks and benefits by adjusting the water level. For example, when too much money is invested in Manchester United, the amount of bets will be tilted, and the bookmakers will worry that this imbalance will bring them the risk of compensation. Then at this moment, they will reduce the possible loss by lowering the odds. The Asian plate will also reduce the total amount of compensation that Manchester United may bring by winning through upswing or precipitation.
