Price Signals
Definition
Price Signals in sports betting the line itself, EV, and timing all provide signals about value and market sentiment.
Price Signals
The price a sportsbook offers IS a signal. So is how that price changes over time.
The Line as Information
When a book sets points over 22.5 at -110, they're saying:
- "We think there's roughly 50% chance he goes over"
- "We're confident enough to take bets on both sides"
The line itself contains their probability estimate (after devigging).
EV as a Signal
Expected Value tells you:
- How much the market disagrees with "fair" odds
- The magnitude of potential edge
- Whether it's worth your attention
| EV Range | What It Suggests |
|---|---|
| < 0% | Negative edge - pass |
| 0-2% | Marginal - probably noise |
| 2-5% | Interesting - investigate |
| 5%+ | Strong signal - rare, verify |
Timing Signals
WHEN the line is where it is matters:
Opening Line
- Where the book first set the line
- Often less efficient (more value early)
Current Line
- Where it is now after market action
- Generally more accurate
Line Movement
- Direction tells you which way money is flowing
- Speed tells you if it's sharp or public
- Magnitude tells you how significant
Price Discrepancies
When books disagree, that's a signal:
- Sharp book at 23.5, soft book at 22.5 = information gap
- One book hasn't adjusted to news yet
- Market inefficiency = potential value
Combining Price Signals
Strong price signal alignment:
- ✅ Positive EV (3%+)
- ✅ Line hasn't moved much (not priced in)
- ✅ Best price available at a soft book
- ✅ Sharp books haven't contradicted
Weak price signals:
- ⚠️ EV positive but line moved toward you (steam already happened)
- ⚠️ Sharp books have different number
- ⚠️ Price only good at one book
Key Takeaway
The price is information. EV is information. Movement is information.
Read all of it before betting.
