Reading Signals: Every Column Explained

What Market %, AI Est., Edge, and Signal columns mean

The Scanner table is the most-used view in Predite. This doc explains every column, every badge, and every filter so you can read signals fluently.

## The Core Columns

When you open the Scanner, you'll see a table with these columns by default:

Market. The market name (e.g., "Will the Fed cut rates in June 2026?"). Click to open the full market detail page. The icon next to the name indicates the platform (Polymarket logo or Kalshi logo).
Category. Politics, Economics, Sports, Crypto, etc. Use the dropdown filter at the top to narrow by category.
Market %. The current market price expressed as a probability. A share trading at $0.40 shows 40%. This is the "market's belief" you're betting against.
AI Est. Our 3-model AI consensus probability. If we estimate 55% but the market is at 40%, there's a 15-point gap that may be edge.
Edge. The difference between AI Est. and Market %, in percentage points (pp). Positive edge = market underpriced (recommendation: buy YES). Negative edge = market overpriced (recommendation: buy NO). Magnitude matters — see the "what counts as a strong signal" section below.
Signal. Our actionable recommendation: - 🟢 YES — buy YES shares - 🔴 NO — buy NO shares - ⚪ HOLD — no clear edge, ignore
Conf. Confidence level of the AI estimate (50-95%). Higher = more certain. Below 60% = use caution; the model is unsure.
Volume 24h. USD trading volume in the last 24 hours. Higher = more liquid, easier to enter/exit.
Liquidity. Depth of the order book at the best price level. Low liquidity (<$1000) means even small orders move the price.

## What Counts as a Strong Signal

Rough rules of thumb:

- **Edge ≥ 5pp:** Worth investigating. Open the market, read the resolution criteria, decide if you have a view.

  • •**Edge ≥ 10pp:** Strong signal. Likely worth a small position if you have time to monitor.
  • •**Edge ≥ 15pp:** Rare. Either a real mispricing or a sign that the resolution criteria are tricky (markets are usually efficient enough that 15pp gaps don't last). Verify carefully.
  • •**Edge ≥ 20pp:** Almost always a sign that something is off — the AI doesn't know about a recent news event, the market is illiquid, or the resolution criteria are ambiguous. Don't blindly take these.

Combine edge with confidence:

  • •High edge + high confidence (>75%) = strongest signal
  • •High edge + low confidence (<60%) = AI thinks there's edge but doesn't trust its estimate — verify manually
  • •Low edge + high confidence = consistent +EV at small scale — fine for bots, less compelling for manual trading
  • •Low edge + low confidence = noise. Skip.

## Filters and Sort

Above the table, the filter bar lets you narrow signals:

- **Platform:** Polymarket, Kalshi, or both

  • •**Category:** All categories or specific ones
  • •**Min edge:** Slider from 0 to 30pp
  • •**Min confidence:** Slider from 50 to 95
  • •**Min volume:** Slider to exclude thin markets
  • •**Direction:** YES only, NO only, or both
  • •**Resolution window:** 24h, 7d, 30d, 90d, or all

Click any column header to sort by that column. Default sort is edge (descending). Holding Shift while clicking adds secondary sort criteria.

## Badges and Pills

Markets can have additional badges next to the name:

- 🔥 **Hot** — high volume in the last hour (>3x normal)

  • •🐋 **Whale** — large wallet just took a position
  • •📰 **News** — recent news article matched this market
  • •⚠️ **Low Liq** — order book depth below $1000 — exit may be hard
  • •🎯 **Arb** — same event also exists on the other platform with a price gap (see Arbitrage page)
  • •🏁 **Closing** — resolution within 7 days (less time for theses to play out)

## Reading the Edge Visually

Edges are color-coded for fast scanning:

- **Green:** Positive edge → buy YES

  • •**Red:** Negative edge (means AI says market is too HIGH) → buy NO
  • •**Gray:** Edge under your "min edge" threshold → noise

The shade intensity scales with edge size — a 5pp edge is light green, a 20pp edge is bright green.

## Common Mistakes Reading Signals

- **Treating "Signal" column as gospel.** It's a suggestion based on a model. Always read the resolution criteria. The model can miss obvious things (e.g., a market about "Will X happen by date Y" where Y already passed — model says edge 30%, actually it's resolved).

  • •**Ignoring confidence.** Edge of 15pp with confidence 50% is much weaker than 8pp with 90% confidence.
  • •**Trading every signal.** With 50+ markets active, you'll see signals all day. Pick the ones with the strongest combination of edge + confidence + liquidity, not every single +EV blink.
  • •**Ignoring volume.** A 15pp edge on a $500-volume market is nice in theory but you may not be able to enter $200 without moving the price 5pp against you.
