If you want to predict what will happen when Team A meets Team B, your best stats to analyze are those generated in their most recent head-to-head matchups at the same venue. The habits of the betting public are fairly constant, so ATS results in general have a longer shelf life, but don’t bother going too far back in time. The 2009 New York Yankees are going to look a lot different than the 2008 Yankees or the 2000 Yankees. (Source: The Sports Bookie Blog)

Financial spread betting is a way to speculate on financial markets in the same way as trading a number of derivatives. In particular, the financial derivative Contract for difference (CFD) mirrors the spread bet in many ways. In fact, a number of financial derivative trading companies offer both financial spread bets and CFDs in parallel using the same trading platform.
Bets on “Winner of Point”, “Scorer of Goal" and similar offers refer to the participant winning the listed occurrence. For the settlement of these offers, no reference to events happening prior to the listed occurrence will be taken into consideration. Should the listed event not be won within the stipulated time frame, all bets will be declared void, unless otherwise stated.
When wagering against the spread, you bet on the team that will cover the betting line, and not necessarily win the game. Obviously by taking the favorite, a bettor believes that team will not only win the game, but also win the game by a certain number of points to cover the betting line. But when wagering on the underdog, that team does not necessarily have to win the game to cover the line. For examples of point spreads and how those bets are won, please keep reading below where we explain betting odds for the spread in detail.
When the point spread was invented in Chicago by Charles McNeil the money line took a backseat. When two unevenly matched teams played, the playing field was leveled by having the favorite give points (for example Chicago Bears –7) while the underdog got points (Minnesota Vikings +7). No matter which team the bettor took the bettor would always risk $110 to win $100. The extra $10 needed to win $100 is called the juice or the vig, it is basically the house’s or the bookie’s take. It’s 10-percent of the bet so it would take $33 to return $30 and $440 to return $400 etc. (winning bettors get the vig back).
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value.  The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
