betting system

Sports betting systems refers to a set of events that when combined for a particular game for a particular sport represents a profitable betting scenario. Since sports betting involves humans, there is no deterministic edge to the house or the gambler. Systems supposedly allow the gambler to have an edge.
Sportsbooks use systems in their analysis to set more accurate odds. Therefore the novice gambler may believe that using a system will always work, it is the general consensus that at some point, the oddsmakers will have adjusted for the system to make it no longer profitable. Very short-lived systems are called trends. Any single event that estimates a selection to have a higher likelihood of winning is called an angle as they are meant to be used in conjunction with other angles and trends to produce systems.
Systems can be deceiving. Any sample space can be constrained enough with meaningless criteria to create the illusion of a profitable betting system. For example, a coin can be flipped with heads being home teams and tails being road teams. Heads and tails each have a 50% probability of landing but if the amount of flips is limited to a small number, it is conceivable to create the illusion of predicting heads will come up 75% of the time.
That, in conjunction with the fact that sportsbooks adjust their odds according to the systems makes it difficult to follow systems indefinitely. The sportsbooks are slower to adjust the odds in some sports versus other sports depending on the number of games played and the amount of money they take in from bettors.
Determining systems is a matter of using computer analysis tools and extracting all the possible games that meet a bettor's criteria. Then the bettor analyzes the results of those games to make a determination if one team is favored over the other.
Factors that are used into determining betting systems are a mix of psychological, motivational, biological, situational factors that, based on past performances, support one team over another. It is generally believed that more than one factor pointing towards a team is needed to have a successful betting system.
Retrieved from Originally, martingale referred to a class of betting strategies popular in 18th century France. The simplest of these strategies was designed for a game in which the gambler wins his stake if a coin comes up heads and loses it if the coin comes up tails. The strategy had the gambler double his bet after every loss, so that the first win would recover all previous losses plus win a profit equal to the original stake. Since a gambler with infinite wealth will with probability 1 eventually flip heads, the Martingale betting strategy was seen as a sure thing by those who practised it. Unfortunately, none of these practitioners in fact possessed infinite wealth, and the exponential growth of the bets would eventually bankrupt those foolish enough to use the Martingale. Moreover, it has become impossible to implement in modern casinos, due to the betting limit at the tables. Because the betting limits reduce the casino's short term variance, the martingale system itself does not pose a threat to the casino, and many will encourage its use, knowing that they have the house advantage no matter when or how much is wageredAs with any betting system, it is possible to have variance from the expected negative return by temporarily avoiding the inevitable losing streak. Furthermore, a straight string of losses is the only sequence of outcomes that results in a loss of money, so even when a player has lost the majority of their bets, they can still be ahead over-all, since they always win 1 unit when a bet wins, regardless of how many previous lossesSince expectation is linear, the expected value of a series of bets is just the sum of the expected value of each bet. Since in such games of chance the bets are independent, the expectation of all bets is going to be the same, regardless of whether you previously won or lost. In most casino games, the expected value of any individual bet is negative, so the sum of lots of negative numbers is also always going to be negative.
In a classic martingale betting style, gamblers will increase their bets after each loss in hopes that an eventual win will recover all previous losses. The anti-martingale approach instead increases bets after wins, while reducing them after a loss. The perception is that in this manner the gambler will benefit from a winning streak or a "hot hand", while reducing losses while "cold" or otherwise having a losing streak. This general idea of increasing bets when conditions are believed to be favorable can improve the odds in games with a memory by using a strategy like card counting. But in a true random memoryless game there is no such thing as a winning streak or losing streak (these notions are gambler's fallacy) so this strategy can't improve the expected winnings in such situations.
One activity where money management based on an anti-martingale approach has a recognized value[2] is speculation and trading. Many financial markets have some cyclical component to them, and the approach of an individual speculator or trader may only be appropriate for one portion of that cycle. Using an anti-martingale risk management scheme will increase profits during time periods when a trading approach is working well, while automatically decreasing exposure during portions of the cycle where trading is unprofitable. This is believed to decrease the risk of ruin for trading.
A betting strategy or betting system is a structured approach to gambling, with a predefined set of actions for bet sizing and timing. Betting strategies are typical in any activity in which money is risked but where the participant has little influence on events with their power limited to the sizing and timing their wagers, i.e. share trading, horse racing, sports picking, casino games etc etc. Betting strategies are based on some logical argument, whether it be based on probability or illusionary patterns, but all are at some level convincing to the particular betting strategist that it will increase their chance of success.
There are two key categories in which betting strategies fall; progression betting systems and staking systems.Progression betting systems involve when and how much to increase or decrease bet sizes after a loss, win or other event. Progression betting systems take either a negative or positive approach, where negative progression betting systems involve increasing bet sizes after a loss whereas positive progression systems will generally increase bet sizes after a win. Negative progression betting systems can be viewed as loss recovery systems, that generally can give the player a profit without having to win more than 50% of the time.[1] Both negative and positive progression systems inherently increase a player's bankroll volatility and so should not be viewed as systems that will eliminate risk entirely over the long run.
The Martingale is the classic progression betting system. In its negative form, it involves doubling your bet size after a loss. This continues until you win. The doubling of bet sizing means that when you do win, the size of the winning bet is greater than the total of previous losses. For example, we can have three straight losses where we have a negative martingale betting string of $5, $10 and $20 for a total loss $35. If we win the fourth negative martingale bet of $40, then we have a net profit of $5. After a winning bet, you drop your bet size back to the initial bet.
The positive martingale involves doubling your bet size after a win, you continue doubling as long as you win until you reach the table limit. After a loss, you reduce your bet size to the initial bet.
The Labouchere System is progression betting strategy like the Martingale but does not require the gambler to risk his stake as quickly with dramatic double ups. The Labouchere System involves using a series of numbers in a line to determine the bet size, following a win or a loss. Typically, the player adds the numbers at the front and end of the line to determine the size of the next bet. When he wins, he crosses out the outside numbers and continues working on the smaller line. If he loses, then he adds his previous bet to the end of the line and continues to work on the longer line. This is a much more flexible progression betting system and there is much room for the player to design his initial line to his own playing preferenceThe D'Alembert is a progression betting system that involves increasing bet sizes during a winning streak and decreasing bet sizes on a losing streak. In the classic D'Alembert system, after a win the player increases their next bet by one unit and after a loss they reduce their next bet size by 1 unit.
Bet spreading in blackjack is an interesting example of betting strategy based on estimating the true odds by card counting. In essence, when you estimate that the house edge is getting higher you lower your bet sizing and when you estimate the house edge is negative then your increase your bet sizing. In fact, when the house edge is very negative you should increase your spread bet to around 20 times your small bet[3]. The argument for bet spreading is that you can counter the fact that you are playing most of the time with a negative expected value by increasing the amount wagered when you have positive expected value to cover the time you are spending with the worst of it. The method of estimating the house edge is typically done via a card counting system.
The Avant Dernier is another popular Baccarat staking system, where your next bet is on the second last winner[5]. So if we had the results Banker win, Banker win, Player win; then our next bet would be on Banker. The Avant Dernier system works well when the results come in longer streaks or alternating patterns.[6] That is, a 5 streak run of Banker wins or an alternating pattern like Banker, Player, Banker, Player, etc. The Avant Dernier System begins to lose when there is alot of 'double chopping', where results come in pairs like Banker, Banker, Player, Player, Banker, Banker.
