Draw your own formula

Take any two of our daily bitcoin series and make a third: a ratio, a difference, a z-score, a percentile rank, a rolling mean. The formula travels in the link and in the image. A formula, not a forecast.

For everyone

The lab is the catalog as arithmetic. Take any two of the daily series this site captures and make a third one out of them: A divided by B, A minus B, a series against its own 30-, 90- or 365-day mean, a z-score, a percentile rank, a rolling mean, a change over N days, a logarithm. The result is drawn with the same hover, the same ranks and the same table as any page here, and the whole formula travels inside the link and inside the shared image, so anyone who opens it sees exactly the line you saw. It is a formula, not a forecast: nothing on this page predicts anything, the arithmetic is stated in words next to the chart, and where the units of the two inputs do not cancel the page says so instead of inventing a name for the result.

Every series the lab can use

2,107 daily series from 100 pages, the same list the picker above offers. Each line links to the page the series lives on, where the same numbers carry their source, their cadence and what is wrong with them.

The lab itself is drawn in the browser: turn JavaScript on to pick two series and an operation. The list above comes from the last build, Oct-23 2026 21:59Z.
