PooCoin volume bars reset at UTC day boundaries

On PooCoin, a daily volume bar totals the trades assigned to that candle, while a rolling 24-hour figure covers the latest 24 hours at the moment it is read. At UTC midnight, a new UTC-day candle begins; that boundary does not make a rolling 24-hour total equal the previous candle.

For a closer look at the chart controls and token-pair context, see Poocoin. The distinction matters because “24-hour volume” can describe either a fixed calendar-day bucket or a moving window, and those totals can diverge even when both are accurate.

What does a daily volume bar measure?

A daily bar adds the eligible trades that fall inside its time window for the selected market pair. On a chart set to 1D, each bar represents one day’s activity; the displayed amount may use a quote currency or a converted value, so check the chart’s units before comparing it with another screen.

The candle’s height or volume label is not a count of unique buyers, wallets, or tokens held. It is an aggregate of trades recorded for that pair during the interval. A swap routed through multiple pools can create activity in more than one market, so adding figures from separate pairs may count related trading more than once.

What changes at UTC rollover?

UTC rollover marks the start of a new calendar day for data grouped on UTC boundaries. Blockchain transactions carry timestamps, and analytics systems use those timestamps to place activity into intervals; the exact display boundary can still depend on the chart’s timezone setting.

To read the transition, select the 1D interval, note the chart timezone, and compare the bar ending at 00:00 UTC with the bar that starts there. If the display uses local time, the visible boundary may fall at a different clock time. Record the timezone along with any figure you share.

How is a rolling 24-hour total different?

A rolling total looks back 24 hours from the current reading time. It continually drops older trades and adds newer ones, so it can change during the day without waiting for midnight. By contrast, a fixed UTC-day candle accumulates trades within a calendar-day bucket and is only complete after that bucket ends.

• Use a daily candle to compare one UTC calendar day with another.
• Use a rolling 24-hour figure to describe recent activity at a specific time.
• Keep the same token pair, units, interval and timezone when comparing readings.
• Wait until a daily candle closes before treating its total as a full-day figure.

A rise in volume shows more traded value or quantity under the displayed measure; by itself, it does not show whether buyers or sellers controlled the market, or whether liquidity improved. Check the pair and recent trades before drawing that conclusion, especially when a small number of swaps could materially affect a thin market.

How should readers compare the numbers?

First decide whether the question concerns a calendar day or the most recent 24 hours, then use the matching measure. For a day-over-day comparison, use completed 1D candles with the same time boundary and units; for current activity, note the time of the rolling reading and compare it with another reading taken the same way.

The next UTC rollover starts another daily bucket, while the rolling figure continues moving through the hours. Whether PooCoin’s displayed value matches another tracker still depends on its pair coverage, conversion method and update timing, so those details should be confirmed before treating two totals as interchangeable.
