Why line movement data matters

Closing Line Value

CLV measures whether you beat the closing number. Getting -3 when the line closes at -4.5 means you found +1.5 points of edge. Tracking CLV over hundreds of bets is the most reliable long-run profitability signal.

Steam Detection

Steam moves are rapid, coordinated line shifts triggered by sharp money. When multiple books move the same direction within minutes, that's steam. Full tick data lets you build models to detect and front-run these signals.

Reverse Line Movement

When the public is on one side but the line moves the other way, sharp money is likely pushing it. Historical movement data is the only way to systematically identify and backtest these patterns.
