๐ Measures
The Measures panel tells you how the rate moved between two points of the chart: the change, the change in % and the yearly rate.
๐ฑ๏ธ Take a measurement

The + button on the Measures bar measures the selected period from its first rate to its last, without clicking on the chart.
๐ Read a measurement
Each measurement is a card showing its dates, the change in % and the number of calendar days; you can also set its line's colour and style. Expand it to change the dates and to see Start, End, ฮ Abs, ฮ % and ฮ%/yr for the pair and for each overlay on the same axis.
ฮ%/yr is the yearly rate (CAGR), with \(d\) the calendar days between the two dates:
See Returns & Growth Rates โ Financial Theory for log returns and compounding.
๐ Several measurements
Each new measurement is added next to the others, in its own colour; ๐๏ธ removes one. They stay until you leave the page.
๐ก Tips
- ๐ Zoom in before clicking, to hit the exact points.
- ๐ฐ Compare the move before and after an event, such as a central bank announcement.
- โ ๏ธ Read ฮ%/yr with care on short periods: a 1 % move in 7 days compounds to about 68 % a year. It means most over 30 days or more.
