Matched betting is a way for opportunistic individuals to take advantage of favorable conditions at a bookmaker and guarantee a profit when sports betting in the United States. With matched betting, a wager is placed at a betting exchange on the opposite result along with the original event wager, so a bettor can collect regardless of the result. Matched betting is an extremely technical concept that demands advanced mathematics skills to perform accurately, and so many bettors use betting calculators to automatically find the right combination of odds listings to guarantee a profit.
Matched betting is a legitimate wagering strategy that has been proven to generate consistent income when used effectively, and requires that a bettor to calculate the cost of placing the bet as it relates to the potential payout on both sides of the wager, taking advantage of bookmaker disparity to ensure a small payout.
While some gifted gamblers can do this manually, automatic betting calculators take much of the legwork out of matching bets by scanning the market for minimal losses and maximum returns on investment before giving instructions on how to place the wagers to turn a profit.
These powerful calculation programs are usually supported by heavy advertising content or through a paid periodic subscription because of the competitive edge they can offer. As there is no national legislation outlawing the use of mathematics, these calculators are legal to use in jurisdictions that permit gambling.
However, there are some factors that can limit the effectiveness of matched betting in practice. The odds that can make matched betting favorable can change on a minute-by-minute basis, and so opportunities to take advantage of bookmaker odds disparity are very limited. Even with the advantage of bet calculation software, successful bettors who are able to earn a full time living with their winnings must dedicate much of their time and efforts to perfecting their craft.
Another limitation to matched booking is the wide latitude bookers have when dictating wagering policy. Bookmakers also have the ability to cancel bets where they feel a mistake was made, and a canceled offset wager from a bookmaker can leave a bettor exposed to the risks of a standard bet without mitigation. Bookmakers can also limit the stakes of or even ban outright those betting accounts which experience regular success at their discretion. For this reason, bettors should avoid regularly taking advantage of high-profile events to avoid detection by bookmakers and a banning that could permanently cripple a matched betting system.
