Lines move for a reason. Understanding why separates sharps from squares.

## What Moves a Line

When a sportsbook sets a player prop — say, Jokic Over 26.5 points at -110 — they're not predicting his exact output. They're setting a number that balances action on both sides.

When the line moves, it means one side is getting hammered. The question is: by whom?

## Sharp Money vs. Public Money

**Public money** is high volume, low sophistication. Casual bettors hammering the over on a big name. Books adjust the line up to balance, but they're not worried. The public loses long-term.

**Sharp money** is low volume, high sophistication. A syndicate drops $50K on the under. The book moves the line fast — not to balance, but because they respect the information.

## How BetonBLK Detects It

BetonBLK captures a baseline for every prop at the start of each day. Throughout the day, every time we fetch fresh odds, we compare current lines to baseline.

When a line moves 0.5+ points, we flag it with:
- **Direction**: up or down
- **Sharp indicator**: is the money moving against the public side?

If the line moves up but the over odds get worse (more expensive), sharps are likely on the under. The book is adjusting the line but making the over less attractive — a classic sharp signal.

## What to Do With It

A line moving toward your side isn't always bad. It means the market agrees with you. But if you're betting the over and the line just dropped 1.5 points with sharp indicators on the under — that's a kill signal.

BetonBLK surfaces this automatically. You don't need to watch lines all day. We do it for you.
