The core numbers
Section titled “The core numbers”| Number | Meaning |
|---|---|
| Floor | The lowest live listing price, in sats per token. No listings means no floor |
| Listings | Real signed listings on the StampDEX order book |
| Volume | Traded value over the stated window, from the source named on the row |
| Holders | Addresses holding the token, from the index |
| Mint progress | Minted supply against max supply |
| Market cap | Price times supply, from the stated source, with a sanity guard |
| Price change | Percentage over the window, from a source or derived from recorded trades |
How a figure is chosen
Section titled “How a figure is chosen”Each figure has an order of preference, and it stops at the first source that answers. For an SRC-20 token:
| Figure | Preference order |
|---|---|
| Floor | Market feed floor, then market feed price, then the index price, then the StampDEX order book’s own lowest unit price |
| Volume | Market feed, then the index, then StampDEX’s own recorded trades |
| Holders | Market feed, then the index, then StampDEX’s own count |
| Market cap | Market feed, then the index, then price times minted supply |
| Price change | Market feed, then the index, then derived from StampDEX’s recorded price history |
A zero or negative floor is treated as no answer, not as a price of zero. Supply figures are carried as strings so a large number does not lose precision on the way to your screen.
The market cap guard
Section titled “The market cap guard”A computed market cap above the total supply of Bitcoin, 21,000,000 BTC, is reported as unknown rather than repeated. This guard exists because of a real reading: a token declaring a max supply of two to the power of sixty-four produced a reported cap of over two hundred million BTC. That is not a market cap, it is a broken input.
Totals name their coverage
Section titled “Totals name their coverage”An aggregate is only ever summed over the rows that answered, and the coverage is
stated beside it. 0.037 BTC (3/106) means three of one hundred and six tokens had a
volume reading. It is not the volume of the whole board.
For stamps, an aggregate floor is a minimum over the collections that reported a positive floor, never a zero standing in for silence, and the response carries a coverage count of how many collections reported.
Price history
Section titled “Price history”Charts draw recorded prices only. StampDEX does not interpolate points or fabricate a curve for a token with sparse trades. A thin market draws a thin chart, and that is the correct picture of a thin market.
Freshness
Section titled “Freshness”Market surfaces are cached server side. The shortest are around 20 seconds and the longest a few minutes, so a number can trail a live trade by that much. See Freshness.
