Market Context
What the market summary panel shows and where the numbers come from.
Overview
Market Statistics
Market Statistics show category vitals at a glance. The platform regenerates the chips from a weekly snapshot, so values reflect the latest run rather than real-time activity. Each chip pairs a current value with a trend arrow over the period noted on the card.
Activity
Listings live in the category.
※Current snapshot
Pace of new listings.
※90-day trend window

※Cards hide automatically when there isn't enough data to draw a meaningful trend.
Analytics
Analytics turn raw stats into deeper signals: per-listing value scores and a generated prose summary of how the period moved. Each appears only when the category has the inputs needed.
Per-listing values
A second row of cards shows up for categories with a public valuation calculator. Each calculator combines expert knowledge and research with market data from our sales, updated regularly as the marketplace shifts. The cards turn that calculator's output into per-listing value signals.
The category's public calculator applied to each listing, averaged across the period.
Nominal Value divided by asking price. Higher means listings are priced low for what they offer.
※Categories without a public calculator don't show these. Nothing is estimated or interpolated.

AI Summary
When available, a short prose summary sits alongside the cards. It's generated from the same period's data and rewritten weekly, with guidance from igitems analysts to keep it accurate. The summary points at what moved most in the last period and what that might mean for someone watching the category. It's informational only. It never recommends an individual listing.
Visualization
Two charts visualize the data over time.
A histogram showing how active listings distribute across price buckets. Reveals where inventory concentrates and how wide the price spread is.
Illustrative data. Bar heights are bucket counts. The live chart on /brainrot-brainrots adapts its bucket boundaries to the category's actual price range.
A line chart with up to four series drawn from earlier sections: Listing Prices and Sold Prices from Market Statistics, plus Nominal Value and Deal Quality from Analytics. Every series is plotted as percent change versus the prior period's average, so the curves are comparable even though the underlying units differ. A series hides itself if there isn't enough data or variance to be informative.

Frequently Asked Questions
How is Deal Quality calculated for igitems listings?
交易质量评分是将挂售商品的公允价值（来自该类别的计算器）除以其要价，然后根据卖家社区评分和卖家等级进行加权。分数越高，意味着相对于该类别中的其他挂售商品，每美元的价值越高。
为什么该类别不显示名义价值或交易质量图表？
这些图表仅出现在通过特定类别计算器连接了公允价值评分的类别中。未连接计算器的类别仍会显示市场标签和价格历史，但不会为其计算基于价值的指标。
igitems 多久刷新一次市场数据？
