// market probability distribution

Where prediction markets
price gold by expiry.

The implied price range for any supported expiry, derived from Polymarket touch-market yes-prices.

XAU · market-implied distribution

Five numbers, not one.

Percentiles carry distribution shape. Your bot sees how wide the consensus is, not just where its center sits.

Direct-from-price math.

Each yes-price enters as P(asset > threshold) at face value. Pool-Adjacent-Violators plus Fritsch-Carlson interpolation keep the curve monotone. No down-weighting by volume.

Honest single-venue flag.

When only one venue has coverage, the venues field says so and confidence drops to medium. You never get a high label from a lopsided pair.
