What is SAR Extended?

Parabolic SAR Extended gives independent acceleration settings for long and short phases, plus a start value and an offset on reversal. It suits asymmetric rules, for example tighter stops on shorts.

SAR Extended formula

Output	Calculation
Next SAR	SAR + AF × (extreme point − SAR), with AF set separately for longs and shorts

How to read SAR Extended in your code

Signal	Meaning	Condition
Long phase	Stop trails below price	Close above the absolute `value`
Short phase	Stop trails above price	TA-Lib reports short-phase SAR as a negative number

Limitations: More parameters raise the risk of overfitting. Note the sign convention when comparing with price. Nothing on this page is financial advice.

Compare the last two closed SAR Extended 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/sarext \
  -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/sarext',
    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 SAR Extended 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/sarext \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=100"
