For each stock token Robinhood publishes a live quote with a bid and an ask, the stock’s volume for the day, a halt flag, and that day’s mint and burn volume. It publishes no history. Every one of those fields describes the present. The reader who wants last Tuesday has nowhere to ask.
What disappears
A quote is replaced by the next quote. The spread at noon is not stored beside the spread at one. If nobody recorded how wide a token’s quote was last Sunday, that width is not recoverable from anything published today.
The halt flag is the same. It says whether the token is halted now. It keeps no list of past halts.
The mint and burn figure covers the current day. When the day turns, the figure starts again. Yesterday’s total is not offered once today’s has begun, a point taken further in reading mint and burn volume for the day.
Why the past matters
A level alone says little. A spread of 4% is wide or normal only against that token’s usual spread at that hour. A day’s mint volume is heavy or light only against its other days. A supply figure becomes flow only when there is an earlier supply to subtract.
Every useful read of a stock token is a comparison across time. A feed that serves only the present hands over one half of each comparison.
Recording is the only way
Some market data can be bought later. Stock prices are archived by many parties and can be backfilled years afterwards. A field that only its publisher sees, and that the publisher does not archive in public, is different. Once it has been overwritten there is nothing to buy.
So the history has to be collected as it happens. NoVo’s collector has recorded every stock token’s supply on every pass since 4 October 2026. From that date there is a row for each pass. Before that date there is none. The same was true of perp open interest, as the open interest history the venue does not serve describes.
What a young record owes the reader
A record that started recently cannot answer questions about a longer span, and it should say so. A weekly flow needs a reading from a week ago. Until there is one, the figure shown covers a shorter window. The dashboards label an average with the span the record really covers.
Gaps deserve the same honesty. If a pass was missed, that reading is missing. Filling it with the previous value would draw a flat line across a period nobody measured. The general principle is in the part of a data product that cannot be bought.
What it becomes
A few weeks of rows answer simple questions: which tokens grew, and whether supply rests every weekend or only did so on the first one observed. A few months answer better ones, such as how supply behaves around earnings or a split. Each of those answers needs rows that were written at the time.
Where to see it
The Stocks On-Chain tab of the Crypto Market Map shows flow over a day and a week from that record. The same readings are served by get_stocks_onchain on the MCP & API, where every reading carries its as_of time and its age in seconds.
