Can you explain what it means to “go against the grain” of the line?


High-stakes gamblers keep an eye on how the lines are changing and keep an eye out for any odd behaviour. A reverse line movement occurs when a sportsbook moves the line in the opposite direction of what would normally be expected. This is a popular phrase often used in the world of sports betting.

Bettors who are looking for these outliers will keep a close check on the lines to see how and how frequently they shift. They would then attempt to profit from these events by betting on their outcomes. But why do gamblers analyse the lines so meticulously? What good does it do them to look for instances in which the line movements run counter to what one would assume based on common sense?

Presently, everything seems blurry. Let’s read some of the more in-depth resources on the topic of backwards line travel.

Incorrectly setting lines in the opposite direction of what should be the case is a common problem at sportsbooks.

To oversimplify, 777 Live Betting sportsbooks make a profit when almost equal sums of money are wagered on competing outcomes of a game. After that time, their sole responsibility will be to collect their commission, often known as their “juice.” Have a look at this example to see what we mean:

Examples of a number of probability curves

So, let’s assume there are $55,000 in bets on New England and $55,000 in bets on Green Bay. Each side has the same stake in the game at stake. No matter which side wins, the bookmakers will take $55,000 for themselves and pay out bonuses of up to $50,000. When all is said and done, this indicates a profit of $5,000.

On the other side, it presents a golden chance to those who can influence the results. This is very rare and the vast majority of bookies will confirm this for you.

As to Why the Line Broke

It’s probably not lost on you how hard it is to strike a balance in a game where each participant receives precisely 50% of the total. This means that sportsbooks have to constantly change their odds to account for fluctuations in both supply and demand.

You might think of it like the price of a stock

If there is a lot of interest in buying, the price will go up. That is to say, think of the situation as being analogous to the value of a stock. When a large number of investors decide they no longer want to own a particular asset, the price of that stock naturally falls as those investors unload their holdings. Because of this, the cost drops. A similar idea is at work when it comes to the betting lines, since the oddsmakers are compelled to make adjustments in response to the unfolding play. This time, let’s refer back to our original example:

Examples of a number of probability curves

To illustrate, suppose that this time there are 110,000 dollars being wagered on New England and zero dollars being wagered on Green Bay.
