Bookmaker quotes are compiled by analysing dozens of parameters. Betting experts have more information than the average user. A sudden change in the odds means that the analysts have gained some insider knowledge. Let's look at two examples:

- Serie A round 26: "Lazio vs Bologna. The hosts are clear favourites, they are among the Scudetto contenders and have not lost 21 rounds in a row. Initially (as soon as the line appeared) the odds on their victory were 1.41. Three days later, it became known that Lazio's main striker Ciro Immobile would not be on the field (due to illness). As a result, the odds on the Eagles rose to 1.57.
- Matchday 20 of RPL: "Zenit vs Lokomotiv. The initial odds on the home team`s victory was 1.85, on the guests - 4.52. Three days before the game it turned out that Anton Miranchuk and Jefferson Farfan will not have time to recover. This was reflected in the quotes: Zenit - 1.52, Lokomotiv - 7.00.

A sharp movement in quotes is never random. It can also be linked to the so-called "overload". It is a situation when many people have started betting on the same outcome. In most cases, it is due to some insider information (e.g., that one of the club's leaders was injured during the pre-match training). Ratio analysis of sports betting allows more information about the match. But do not forget about BetWinner Bonuses, which can be obtained for registration in the online bookmaker's office. This is another advantage of sports betting.
