Inside the Book: What Moves the Line?

Once your have a firm grasp of the basics, you will see how easy it is to utilize SideLines to facilitate the specific wager you have identified. The beauty of SideLines is that it compiles a wealth of sports information and sports-wagering capabilities in one desktop application. Many sports bettors follow line movements to determine where they will "lay" or "take" odds. The smart bettors know that you don't win at gambling by betting on a team, but you win by betting value. There are many factors that dictate the movement of lines. There are late-breaking injury reports, weather conditions, and heavy action on one side of a game. All of which can affect which direction a line could move. By utilizing all that WSEX SideLines has to offer, you will be able to determine where the "big money" is coming in on each game, find out if the wind is blowing out at Wrigley Field, and be the first to know if Pujols is healthy.

Now rarely is the action perfectly balanced, thus lines are moved to attract bettors to the side that the house needs more action, and away from where there is too much action. Wherever the action goes, bookmakers respond accordingly by moving the line to make the other side more attractive to bettors. A typical line movement in football would be either an adjustment to the moneyline price in order to encourage or discourage action (i.e., Team A -10 (-110) to -10 (-111)), or an adjustment to the pointspread (often accompanied by a change in the moneyline, i.e., Team A from -10 (-110) to -10.5 (-105)). These techniques help sportsbooks like WSEX control positions. However, whenever the spread is adjusted, sportsbooks run the risk of getting "sided" or "middled" (explained below). This is the sort of "cat and mouse" game that drives line movements.

Using SideLines to follow line movements brings an added dimension to sports wagering that can help you determine exactly where you want to be on a particular bet.

Terms Defined:

Sided – To win one side and tie the other. For example, if you lay -2 1/2 and take 3 on the same game and the favorite wins by 3, you've SIDED the book.

Middled – To win both sides of a game. For example, if you bet the underdog +3 1/2 and the favorite -2 1/2 and the favorite wins by 3, you've MIDDLED the book.
