About BulbaStats

Computed by weighted-average cost basis over observable market trades. A buy raises the average, a sell realizes the difference against it, and the 4% taker fee is charged into cost or deducted from proceeds. Items obtained in-world — mined, crafted, gifted — never appear as a purchase, so selling them realizes their whole price as profit. Every player page counts those units separately and says so. It measures trading, not wealth creation.

Holdings are valued at the current mid of their variant. Items with no quoted mid are excluded rather than valued at zero, and the count of excluded items is shown, because “we don't know” and “worth nothing” are different claims. On a thin book a mid can move a long way on one order, so treat these as indications.

The BulbaStore account holds roughly 92% of resting orders and is a counterparty to most trades. Leaving it in a ranking drowns out every human trader, so leaderboards exclude it by default and order-flow statistics report it separately. Its cancel rate reflects requoting to track price, not failed trades.

One trade produces a taker leg and one maker leg per resting order matched. Per-player volume counts a player's own legs, so summing volume across players exceeds market volume — that's the intended reading of “how much did this account trade”, not a double-count of the market.

Windowed figures like “last 7 days” are anchored to the most recent trade in the dataset, not the wall clock. Aggregates are computed over a cached crawl, so a wall-clock window would make the same data yield different numbers as the cache ages. Order age and book staleness do use real time, since those are genuinely live quantities.

Volatility is the standard deviation of log returns between consecutive candle closes, deliberately not annualized. Price change returns nothing at all unless a candle old enough to compare against exists, rather than silently comparing to the oldest bucket available and labelling it “24h”.

The 4% taker fee is debited from the buyer and credited to no bank account. Market-wide currency totals therefore shrink as volume grows. This is upstream behaviour and not an artefact of the aggregation.

Simulated locally against the book as it stands, ignoring the taker fee. A real order also moves the price it is being measured against, so the curve is a floor on cost, not a quote.

Direction of currency, not profit. A pair's net flow is the diamonds one account received from the other minus what it paid back; the receiver handed over goods worth it. Taker fees are excluded because they go to the treasury rather than the counterparty, so the figure is strictly what moved between the two accounts.

Minecraft stack size is a property of the item — 64 for most blocks, 16 for eggs and pearls, 1 for tools — so a per-stack price is a per-row multiplier, not a constant. A shulker box is 27 stacks. Only unit prices scale with the toggle: spread stays a ratio and volume stays a total.

An order parked far from mid will not trade, so total resting value flatters a book. The median resting order sits a long way out, and only a small fraction of all resting value falls within 5% of mid — the distance bands on the orders page separate depth you could realistically hit from a market maker's ladder.

Stat tiles built from the trade record carry a sparkline and a change against the prior period. The book-structure tiles — two-sided books, median spread — carry neither on purpose: the API exposes the order book only as it stands right now, so there is no history behind them and a trend line would be invented. Changes in a share are given in percentage points, because a share moving from 40% to 43% has risen three points, not 3%.
