Signals are not magic. They are labels for observable market conditions that deserve either attention, verification, or silence.

## Direct answer

- Momentum measures continuation, not certainty.
- Divergence catches conflict between short-term and daily moves.
- Flow shows where large trades cluster, not whether whales are right.
- Resolution risk is the signal that says the rules may matter more than price.

## What are Polymarket signals?

Polymarket signals are rule-based observations over live market data. They can flag continuation, reversal pressure, large-trade clusters, unusual volume, or settlement ambiguity.

A signal is most useful when it includes evidence, confidence, historical context, and a next action. Without those, it becomes a noisy alert.

## Four common signal families

Momentum looks for moves that persist across time windows. Divergence looks for short-term movement against the 24h trend. Flow tracks large trades and wallet clustering. Resolution risk flags markets where source or oracle status deserves verification.

Each family answers a different question. Mixing them into one vague score makes the interface feel simple but hides the reason the market was surfaced.

## Where signals fail

Signals fail in thin markets, wide spreads, single-wallet bursts, stale source conditions, and near-resolution situations where price is already pinned. They also fail when users read them as predictions instead of observations.

The fix is to pair every signal with context: volume, liquidity, source, market age, related markets, and the action a user should take next.

## Use signals as a queue

The best way to use signals is to rank attention. Open the strongest market, inspect the evidence, check source risk, then decide whether to watch, alert, or ignore.

That workflow keeps signals useful without turning them into false certainty.

## FAQ

### Are Polymarket signals predictions?

No. They are observations about market behavior and source risk. They help decide what to inspect next.

### Which signal matters most?

It depends on the workflow. Momentum is useful for repricing, flow for attention, and resolution risk for settlement safety.

### Can signals be backtested?

Some can be backtested against historical post-signal movement. Others, like resolution risk, are better treated as forward-looking safety checks.
