What is NATR?

Normalized Average True Range expresses ATR as a percentage of the close, so volatility can be compared across symbols with very different prices.

NATR formula

Output	Calculation
NATR	ATR ÷ close × 100

How to read NATR in your code

Signal	Meaning	Condition
Comparing markets	Which symbol moves more	Higher `value` is more volatile
Volatility rising	Candles getting larger relative to price	`value` rising

Limitations: Direction is not included, and absolute levels depend on timeframe. Nothing on this page is financial advice.

Compare the last two closed NATR 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/natr \
  -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/natr',
    headers={'Authorization': 'Bearer YOUR_API_KEY'},
    params={'exchange': 'binance', 'symbol': 'BTCUSDT', 'timeframe': '1h', 'results': 2, 'backtrack': 1},
)
data = resp.json()
prev, last = data['value']
print('value', prev, '->', last)
print('rising' if last > prev else 'falling or flat')

Get historical NATR 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/natr \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=100"

Get NATR for multiple symbols

Combine NATR with other indicators in one request. Each exchange, symbol and timeframe combination is one construct: Basic allows 1 per request, Pro 3 and Expert 10.

NATR API FAQ

What does the NATR API return?

It returns value, plus a timestamp for the request. Results are JSON.

Is the latest NATR value final?

No. The newest value belongs to the candle still forming and can change until it closes. Add backtrack=1 to read the last closed candle.

Which NATR settings can I change?

You can set period. See the parameters table above for defaults.

Can I get NATR for US stocks?

Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
