What is Aroon?

Aroon, created by Tushar Chande, measures how recently price made its highest high and lowest low within a window. Recent highs push Aroon Up towards 100 and recent lows push Aroon Down towards 100.

Aroon formula

Output	Calculation
Aroon Up	(period − candles since highest high) ÷ period × 100
Aroon Down	(period − candles since lowest low) ÷ period × 100

How to read Aroon in your code

Signal	Meaning	Condition
Uptrend	New highs are recent	`valueAroonUp` above 70 and `valueAroonDown` below 30
Downtrend	New lows are recent	`valueAroonDown` above 70 and `valueAroonUp` below 30
Trend change	Leadership switched	`valueAroonUp` crosses `valueAroonDown`

Limitations: Aroon only looks at when extremes occurred, not how far price moved, so a tiny new high scores the same as a large one. Nothing on this page is financial advice.

Compare the last two closed Aroon values

Use backtrack=1 to skip the candle still forming, and results=2 to compare the last two closed candles. Arrays run oldest first.

curl -G https://v2.taapi.io/indicator/aroon \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=2" \
  --data-urlencode "backtrack=1"

import requests

resp = requests.get(
    'https://v2.taapi.io/indicator/aroon',
    headers={'Authorization': 'Bearer YOUR_API_KEY'},
    params={'exchange': 'binance', 'symbol': 'BTCUSDT', 'timeframe': '1h', 'results': 2, 'backtrack': 1},
)
data = resp.json()
prev, last = data['valueAroonDown']
print('valueAroonDown', prev, '->', last)
print('rising' if last > prev else 'falling or flat')

Get historical Aroon values

Add results to return a series for backtesting or charting. The last element is the most recent candle.

curl -G https://v2.taapi.io/indicator/aroon \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=100"
