Why short windows
By the time a coin reads plus forty percent on the day, the move is usually over. The point of this page is different — to see the ramp in its first minutes, while it continues.
So the main windows are short: fifteen and thirty seconds, one minute, five minutes, a quarter hour, half an hour and an hour. Every other window is shown next to the one you pick.
Why there is no one-second window
Because it would be fiction. Prices are sampled from all six venues every five seconds — as often as they can be polled without hitting their limits. So the shortest honest window is fifteen seconds, holding three samples.
A one-second change would be built from two adjacent readings and would show the last price jittering in the book, not the market moving. For the same reason the hourly window is unavailable right after a restart: the hour has not passed, and such windows stay dimmed until they fill.
Volume decides almost everything
This is the main filter, and without it the list is useless. On a pair turning over a thousand dollars a day, one order moves price ten percent — formally a record gain, in substance nothing. Such pairs do not merely add noise, they push real moves off the top rows.
The threshold is a field: at ten million only large coins remain and a one-percent move is meaningful; at a hundred thousand small coins appear with moves of tens of percent — some real, some an empty book.
Reading the "other windows" column
This is the most useful part of the table. One number alone means little; eight side by side form a picture:
- Steady gains across all windows — a trend.
- Large gains in short windows, nothing in long ones — the move just started.
- Gains in long windows, losses in short ones — it is over; too late to enter.
- Up on the minute, sharply down on the day — a bounce on a collapsed coin, not a rally.
What the page does not say
It shows that price has already moved and says nothing about whether it will keep moving. Sharp spot rallies often end in equally sharp reversals, especially on thin pairs. This is an observation tool, not a buy signal.
