Aroon Indicator

Aroon answers a time question. Aroon Up near 100 means the high of the window happened on the most recent bar. Aroon Down near 100 means the low happened just now. A strong uptrend keeps Aroon Up high and Aroon Down low, because new highs are fresh and new lows are old. It does not measure the size of the move, only its recency.

When both lines are low, no new extreme is recent: the market is drifting inside the window. Crossovers mark a change in which extreme is fresher. A crossover with both lines near 50 is a weak event. A crossover with one line at 100 and the other at 0 is the textbook trend reading.

Aroon Up above 70 and Aroon Down below 30 is the usual bullish regime. It says highs are fresh and lows are stale. Price still has to be making those highs. Check the chart. The indicator can read 100 on a one-tick high.

Aroon Down above 70 and Aroon Up below 30 is the bearish regime. Same caution: recency is not magnitude.

Treating an Aroon cross as a price target. It has no price in it, only bar counts. Also using a tiny N so that every other bar is a new "trend."

A market can make a new high by one tick and then collapse. Aroon Up will have been 100 at the worst moment. Use it as a regime description beside the swings, not as an entry trigger alone.
