What is VHF?

The Vertical Horizontal Filter, from Adam White, tells you whether a market is trending or congesting by comparing its net range with the total path travelled.

VHF formula

Output	Calculation
VHF	(highest close − lowest close) ÷ sum of \|close changes\|

How to read VHF in your code

Signal	Meaning	Condition
Trending	Range is large relative to path	`value` rising
Congesting	Lots of movement, little progress	`value` falling

Limitations: It identifies market state only and has no direction. Nothing on this page is financial advice.

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

Get VHF for multiple symbols

Combine VHF 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.

VHF API FAQ

What does the VHF API return?

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

Is the latest VHF 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 VHF settings can I change?

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

Can I get VHF for US stocks?

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