Droppingodds.com service offers you a very helpful instrument to follow the sports lines and odds movements.
The data are in real time (auto refresh at every minute) from Pinnaclesports, one of the bookmakers with the lowest margins and highest limits in the betting market.
The columns include the open (early) and the current spreads/odds. They show also the trend (which is the sense of the last movement) and the hour of this last change. A graph and a history of all the changes are available.
You can select the events by league or by day and order them alphabetical or by kick-off time. You can sort all the games, the events with any movement, the games where spreads or only odds have changed.
