What is Hilbert SineWave?

The SineWave indicator turns the measured cycle phase into a sine and a lead sine, which is the same wave advanced by 45 degrees. Their crossings anticipate cycle turning points.

Hilbert SineWave formula

Output	Calculation
Sine	sin(phase)
Lead sine	sin(phase + 45°)

How to read Hilbert SineWave in your code

Signal	Meaning	Condition
Cycle low	Potential upturn	`valueLeadSine` crosses above `valueSine`
Cycle high	Potential downturn	`valueLeadSine` crosses below `valueSine`

Limitations: In trends the two lines run together and crossings mislead. Use trend mode as a filter. Nothing on this page is financial advice.

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

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

Get Hilbert SineWave for multiple symbols

Combine Hilbert SineWave 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.

Stream Hilbert SineWave in real time

Subscribe over WebSocket to receive new values every 5 seconds while the candle is forming. Streaming supports 1m, 5m, 15m and 1h, and uses interval where REST uses timeframe.

Hilbert SineWave API FAQ

What does the Hilbert SineWave API return?

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

Is the latest Hilbert SineWave 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.

Can I get Hilbert SineWave for US stocks?

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