In response to this the bookie will increase their margin on the popular line (to stop people betting) and will reduce their margin on the less popular line (to encourage betting). To determine the odds for a particular market, you need to understand how the market works and what factors influence it. Start by researching the market you are interested in and studying its patterns and trends.
