Freebets4all | AutoMatcher
The AutoMatcher (no longer operating due to unavailability of odds data) was 世界上第一个自动匹配投注赔率编译器.
该系统收到了50多个体育博彩提供商对体育博彩赔率的更改, up to 100 times per second via a WebSocket. The odds were then stored in both SQL and NoSQL format and could be analyzed and queried to identify closely matching odds for the same betting market (e.g., correct score, match winner, 以及赛马获胜者)在不同的博彩公司之间寻找匹配的投注机会.
The opportunity could then be selected to show the user how to make a risk-free profit on the arbitrage situation by covering all outcomes of the event, 经常使用庄家的免费赌注和奖金来增加奖金. The AutoMatcher then generated instructions in multiple languages to show the user how to place the bets using a variety of techniques, such as slight variations on a mathematical formula, 这取决于庄家提供的奖金类型.
This pioneering system helped Freebets4all become the UK's best-known matched-betting website, generating revenue via affiliate marketing and well-loved by the matched-betting community of 80,000+ users.
