A reward window has size, spread, and dates

A market can display a reward program and still reject your assumption that every resting quote qualifies. The eligibility boundary lives in the market configuration.

Polymarket's market-details documentation exposes reward settings for the minimum qualifying size, maximum qualifying spread, and dated allocations.

Start with the minimum size

The rewards minimum size is a market-level constraint on the order size that can qualify. A quote below that threshold may be valid liquidity and still be outside the reward calculation.

Keep the qualifying size beside the order record. Do not infer it from a neighboring market or from an older snapshot.

Check distance from the midpoint

The maximum qualifying spread describes how far a resting order can be from the midpoint and still qualify. A quote can remain on the book while drifting outside that boundary.

If the strategy keeps a quote alive after the market moves, refresh the midpoint and the reward setting before calling the quote eligible.

Treat allocations as time-bound

Reward allocations carry a start date and an end date, with a daily rate and a total amount. An allocation that was active yesterday is not evidence that the same funding exists today.

Record the allocation window used for each report. This makes a payout review a dated calculation rather than a timeless assumption.

Separate reward status from trade status

A reward setting does not say that your order filled, and a fill does not prove that the order met every reward condition. Keep eligibility, execution, inventory, and payout as separate fields.

The useful question is not whether a market advertises incentives. It is whether the current size, spread, dates, and executed liquidity all line up for the specific quote.
