How to Interpret the Live Signals Page

The Live Signals page is the heart of SharpSideBaseball. It's a real-time terminal of every MLB market where sharp money is meaningfully moving the line — across sportsbooks (via The Odds API) and prediction markets (Kalshi, Polymarket, Robinhood, Coinbase). This guide walks you through every column so you know exactly what you're looking at.

The date tabs

At the top of the feed you'll see Today · Tomorrow · This Week · Future · All. These filter the slate by first pitch. Counts next to each tab show how many active signals fall in that window. Start on Today for in-day action; flip to Tomorrow the night before to pre-stage positions.

Event

The left-most column. Shows the matchup (e.g. Yankees @ Red Sox), the platform the signal came from (DraftKings, Polymarket, Kalshi, etc.), the market type (ML, Run Line, Total, F5, YRFI, player prop), and how many minutes ago the move was detected. When available, probable pitchers and their ERA / K/9 chips appear underneath for instant context.

Click the event title to open a matchup insight dialog. This is where SharpSideBaseball surfaces the story behind the number — public vs. sharp splits, reverse line movement, and narrative context scraped from market data. If an event title shows a small flame icon, that means a detailed insight is available.

What's inside the insight dialog

When you click an event, a dialog opens with three layers of information:

• Headline narrative — A one-sentence summary of the sharp action. For example: "The Yankees are an incredibly popular public play, drawing 82% of the tickets. However, sharp money is actively taking the points and backing the Blue Jays on the run line." This is generated from live public-betting splits and line movement data.
• Line movement — The opening price vs. current price for the listed side, so you can see exactly how far the market has moved.
• Public & Sharp breakdown — When available, you'll see:
  • Public side — Which team is getting the majority of tickets (small, recreational bets) and the ticket percentage.
  • Sharp side — Which team is getting the majority of handle (larger, professional-sized bets) and the handle percentage.
  • Bullet points — Specific observations like "Blue Jays RL: 64% of handle vs 38% of tickets" or "Reverse line movement detected on Under 8.5."

If no public/handle splits have surfaced yet for that matchup, the dialog will show the line movement alone and a note that heat is based purely on cross-book line movement. Splits tend to appear closer to game time as betting volume concentrates.

Live game context (in-progress games)

If a signal is on a game that's already underway, the row title is tagged with a pulsing LIVE indicator showing the current inning and score, and the insight dialog adds a Live game context block at the top. This is pulled straight from the MLB Stats live feed (refreshed every ~15 seconds) and explains why the line might be moving on the field:

• Current inning and half, outs, balls/strikes
• Score and which team is batting
• Runners on base, with a flag when runners are in scoring position
• The last completed play (e.g. "Stephenson doubles to deep right, Friedl to third")
• A plain-English Why string that you'll also see in Heat Alert toasts — e.g. "Reds have runners in scoring position with 1 out, trailing by 1 in the bottom of the 7th. Last play: Stephenson doubles to deep right."

Heat Alerts you've armed will append that same Why line to the push notification, so you don't have to guess what just happened on the field when the market re-priced.

Heat

A 0–100 score combining cross-book consensus, steam, reverse line movement, public handicapper agreement, weather, and pitcher matchup quality. The colored bar gives you a visual read; the badge labels the tier (Low → Medium → Hot → Scorching). A full breakdown lives in How Heat Scores Work.

Side

Which side of the market the sharps are backing — e.g. Red Sox ML, Over 8.5, Yankees -1.5, YRFI. This is the side whose implied probability is rising. If the column truncates a long label, hover to see the full text.

Move

How far the implied probability has shifted toward the listed Side, measured in percentage points (pts), with the raw price transition underneath (e.g. -120 → -148).

• ▲ +5.1 pts → sharps are pushing money toward this side; the market now thinks it's 5.1 points more likely to hit than it did at the snapshot.
• ▼ −3.2 pts → money is drifting away; conviction is fading.

Implied probability is the apples-to-apples metric across sportsbooks and prediction markets, which is why we use it instead of raw odds % change.

Vol

Total estimated volume across every market on that game, aggregated from sportsbook proxies (ML + Run Line + Totals + Props) and real dollar volume from matching Polymarket / Kalshi contracts. A high Heat with low Vol is a soft signal; high Heat with high Vol is the kind of move you actually want to act on.

½-life · Log · Alerts

The right-most column packs three Pro-tier actions:

• ½-life (Move Duration Estimate) — How long this type of move typically holds before fading. Comes with a confidence tier (High / Medium / Low) based on heat, window length, and source consensus. Use it to decide whether to chase now or wait.
• Log (Wallet icon) — One-click adds the current market to your Positions log at the current price so you can track P&L and share a verified pick later.
• Alerts (Bell icon) — Arms a Heat Alert. You'll get an in-app toast, a push notification, and an email (via notify.sharpsidebaseball.com) if Heat ticks up another tier, with a fresh duration estimate and — for live games — the plain-English Why string attached.

Free users see the data on five events per day. Pro unlocks all events, all durations, and both action icons.

Reading a row in 5 seconds

A practical scan:

1. Heat tier — Scorching or Hot? Worth a closer look.
2. Side + Move — Which way and how hard? +4 pts or more on a Total is meaningful; +6 pts on an ML is significant.
3. Vol — Is real money behind it?
4. Click the event title — Check the insight dialog. Are sharps fading the public? Is there reverse line movement? That narrative is often the difference between a good number and a great one.
5. Pitcher chips — Does the matchup support the direction? (Two aces + Over move = caution; two aces + Under move = confluence.)
6. ½-life — Do you have time to wait, or should you grab the number now?

If five of those six line up, you've found a signal worth acting on.

Pro tip: the "warming up" state

When the page first loads (or right after a server refresh), you may see a short "Collecting baseline prices…" message. Signals are detected by comparing price snapshots, so the very first tick has nothing to compare against. After ~30 seconds the second tick lands and the feed populates.
