What is Acceleration Bands?

Acceleration Bands, from Price Headley, place an upper and lower envelope around a simple moving average, with band width based on each candle's relative range. They are used to spot accelerating moves that close outside the bands.

Acceleration Bands formula

Output	Calculation
Upper	SMA(high × (1 + 4 × (high − low) ÷ (high + low)))
Middle	SMA(close)
Lower	SMA(low × (1 − 4 × (high − low) ÷ (high + low)))

How to read Acceleration Bands in your code

Signal	Meaning	Condition
Upside acceleration	Breakout above the envelope	Close above `valueUpperBand`
Downside acceleration	Breakdown below the envelope	Close below `valueLowerBand`
Return to mean	Move losing energy	Close back inside the bands

Limitations: Bands widen after large candles, so signals can fade precisely when volatility is highest. Nothing on this page is financial advice.

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

Get historical Acceleration Bands values

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