The Cold Line
The short answer
When the line moves opposite to where the money appears to be going.
What is RLM (reverse line movement) in sports betting? When the line moves opposite to where the money appears to be going. In plain terms: most tickets sit on one team, yet the line walks the other way. The ticket count didn't move that number — bigger, sharper money did. “These reverse line movements are generally sharps coming in late — but tonight, it's clearly squares.” Let's use this example. Seventy percent of bets are on Kansas City minus seven, but by kickoff the number is minus six. The crowd is on one side while the price chases the other — a classic sign the respected money disagrees with the room. Lines and prices can differ by sportsbook. Nothing here guarantees a result or tells you to bet. Lines move and books differ. Nothing here is a guarantee or a command to bet — it's how the number works.
Knowing the language is step one — knowing the true price is the edge. The Cold Line’s signal desk tracks the no-vig fair number and the closing-line value behind terms like this, before the market moves.
