A scanner is useful when it turns thousands of markets into a clean research queue, not when it simply lists prices.

## Direct answer

- A good scanner ranks attention by movement, liquidity, spread, and settlement clarity.
- Resolved, expired, and low-liquidity markets should not pollute the default live view.
- The next action matters: inspect, verify, watch, alert, or ignore.
- Scanner rows should link directly into market detail, alerts, and API context.

## Direct answer

A Polymarket market scanner is a ranked view of active prediction markets that helps users find meaningful probability moves, liquidity changes, and resolution risks. The best scanner is not a price table; it is a workflow that says which market deserves attention and what to verify next.

## How to scan markets

The safest prediction-market workflow separates attention, evidence, source quality, and next action. A probability move can be important, but it is not useful until the market is liquid enough, the rule is clear enough, and the user knows what to verify next.

- Start with active, liquid markets only.
- Rank by 1h and 24h movement after spread and liquidity checks.
- Separate research observations from resolution-risk jobs.
- Open the market detail before acting on the headline probability.

## What to verify before trusting the move

Good research tools keep the boring details visible. Expiry, resolution source, official status, spread, liquidity, and related markets often explain why a headline probability should be treated carefully.

- Is the market still active and unresolved?
- Is the spread tight enough for the move to be meaningful?
- Did 24h volume confirm the move?
- Does the resolution rule match the plain-English headline?

## How Orrery handles it

Orrery's scanner keeps live-research markets separate from pinned, resolved, and expired rows. It exposes category, liquidity, volume, spread, score, and action labels so the scanner becomes the first step in a research loop.

Orrery is not a broker and does not provide trade recommendations. It ranks research work, explains market structure, and keeps resolution rules visible so humans and agents can make better verification decisions.

## FAQ

### What should a Polymarket scanner show first?

It should show live markets with meaningful movement, enough liquidity, a readable spread, and a clear next action.

### Should resolved markets appear in a scanner?

Not in the default live scanner. They belong in resolution verification or archive views.

### Is a scanner a trading signal?

No. A scanner ranks what to inspect. It does not recommend buying or selling.
