Orderly Predict

For a Predict round, the fill generated at round expiry has a positive executedQuantity equal to the settled position size. Its executedPrice is always the UP-book settlement price R, exactly 0, 0.5, or 1 — treat these as legitimate fill values, not as missing or filtered-out data. An UP position’s settlement fill pays R per share; a DOWN position’s settlement fill pays 1 - R per share, even though the recorded executedPrice is the same R. See Positions and Settlement for how this fill appears in trade history.
