The bars
Aroon
Aroon Up is 100 and Aroon Down is 12. That reads as an up trend: the new highs are recent and the last low is old.
- What it says
- The highest high of the last 26 bars came on the last bar; the lowest low came 22 bars ago. The oscillator (Up minus Down) is +88.
- How it is read
- Up above 70 with Down below 30 is read as an up trend, and the other way round as a down trend. Both below 50 means no new high or low for a while. A cross of the two lines is often read as an early sign of a new trend.
- Read it with care
- Aroon only counts bars since the extremes, not how far the price moved: a tiny new high scores the same as a big one.

How old is the last high?
Tushar Chande's Aroon looks at the last 25 bars plus the current one and asks how many bars ago the highest high and the lowest low came. A high on the last bar scores 100 for Aroon Up; a high 25 bars ago scores 0. Aroon Down does the same for the lowest low. In a trend, one of the two keeps scoring high while the other fades.
