Catch the old price after a sharp book moves the line.
When a sharp book like Pinnacle moves a line, slower books often keep the old price for a few minutes. Steam Chaser finds those old prices while they last, with the move, the fair odds and every book's odds. It is free with an email address.

What Steam Chaser helps you review
Who this tool is for
Coverage depends on supported books, markets, and user location
Player props and game lines across supported sports, where a sharp reference book has current prices.
Sportsbooks, DFS apps and exchanges that Upside covers. Availability depends on your location and accounts.
Upside scans 30+ sportsbooks, DFS apps, exchanges, and prediction markets across the product, but each tool has its own coverage rules and data availability.
What to check before making your own decision
Start with the move
Each play shows which sharp book moved, from what price to what price, and how many minutes ago. Fresh moves leave the most room before slower books catch up.
Check the price that is left
Compare the old price still on offer with the fair odds after the move. The gap between them is the estimated edge.
Open the chart and the books
Tap a play to see its price history and every book's odds. Confirm the market, line and start time before you act.
Act quickly or skip it
Old prices usually last minutes. If the price has moved by the time you reach your book, skip the play rather than chase it.
Before relying on the data
- Is the old price still available at your book, or has it already moved?
- How big was the sharp move, and did more than one sharp book confirm it?
- Does the edge still hold after you convert the price to implied probability?
