Unless you are the one moving the line, as in the sharp guy action they are moving off of, you shouldnt see this. Book's dont work this way and dont have the technology setup to pull the rug out on every bet depending on who the bettor is. They would give you the boot rather than piss you off this way and see this thread about them. Now, its possible you are betting the popular side right before the game. It's common for favs and totals to go up and the books typically move lines up or stay where they are. Players bet overs and favorites. Its less common they move down but do more so on super big spreads.

Now, if you really want to test what you think you are seeing, Next time you see a big move as you are trying to get the bet in, go to SBRodds.com and click the line you are betting and look at the line history. You will be able to see if the big bookmakers are moving that way or if yours is going in the opposite direction. Id be surprised if you saw Bookmaker, Betonline and Pinnacle moving one way and your book moving the other.
