What Is the Rate of Change Indicator

The rate of change is the change from the close fourteen days ago to today's close, written as a percentage of the older close: zero when the two are equal, plus when today's is higher, minus when lower. This paper shows you gold's readings of 2025 drawn from real closes — +8.6 percent in April, +12.9 percent in October — the idea as two height marks on a door frame with the growth between them as a percent, the line under the daily chart, the arithmetic for one day, and where the indicator is found on your platform.

The change over two weeks, as a percent

The rate of change is the change from the close fourteen days ago to today's close, written as a percentage of the older close. Zero means no change in two weeks; plus means today's close is higher, minus means lower. On 22 April 2025 gold's reading was +8.6 percent. On 20 October it was +12.9 percent, the biggest two-week rise of the year. It is the momentum indicator with 100 subtracted — the same two closes, the same fourteen days — written as a percent so it can be read across markets.

Height marks on a door frame

The picture is a door frame with height marks on it. A mark from two weeks ago and a mark from today, and the growth between them written as a percentage of the older mark: 266.58 dollars on a mark of 3114.04 is 8.6 percent. The same growth on a taller child is a smaller percent, because the older mark is the yardstick. Each day the older mark moves forward one day and the newer mark is today's close, so the frame is re-read daily. The rate of change is that percentage.
