Line movement
For every game on the slate, how the consensus total and the moneyline moved from the open (the earliest captured line) to the latest line. Steam is flagged when the total moved a half run or more, or a moneyline side moved 20 cents or more. This is where the market moved, with the book count behind each number. It is not a prediction of the result.
Open is the earliest line we captured; latest is the last line on or before first pitch. Consensus is the median total and the average price across the books in that snapshot. The moneyline market (h2h) is thin in this dataset, so many games show no moneyline. A line moving is information about how the market priced a game, never a guaranteed outcome.
