Money line is the basis of the sport betting. The aim of every bookie is to create quotations that will meet all expectations of the clients. This will allow receiving balanced financial flows and guaranteed profit.
Every bookmaker office should create and correct its money line independently. But in practice the situation is absolutely different. Sometimes small bookies can use coefficients proposed by more popular and large bookmakers.
At first, the initial money line is formed. The coefficients from local small bookies (if we speak about unpopular or local sport event) are put into the base of the line. This stage is for creating the preliminary quotations. The maximum bets are very small. No office will propose serious variants being not sure that the bets are distributed rationally.
Around one day prior to the match, the large bookmakers propose their own line (if we speak about tennis). Their analysts have the results of response on initial coefficients. The limits are rather strict on this stage.
After publishing the lines of the large bookies, the thorough analysis of the financial flow begins. By the time of widespread betting the bookie has readjusted coefficients which ensure the correct distribution of financial flow. Each bookie keeps an eye on its rivals. All together they participate in building profitable line.
Of course, the situation when the coefficient on definite outcome is decreased, this will lead to decrease in coefficient. And if the bet is left unclaimed, the bookmaker increases its efficiency by the means of increase of coefficients.
