What is Phasor Components?

The phasor endpoint returns the two components the Hilbert Transform produces: in-phase and quadrature. Most users work with higher-level outputs, but these are useful for building custom cycle tools.

Phasor Components formula

Output	Calculation
In-phase	Detrended price delayed to align with quadrature
Quadrature	Hilbert Transform of the detrended price

How to read Phasor Components in your code

Signal	Meaning	Condition
Raw components	Inputs for custom cycle calculations	`valueInPhase` and `valueQuadrature`

Limitations: These are building blocks and have no standalone trading interpretation. Nothing on this page is financial advice.

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

Get historical Phasor Components 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_phasor \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=100"

Get Phasor Components for multiple symbols

Combine Phasor Components 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 Phasor Components 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.

Phasor Components API FAQ

What does the Phasor Components API return?

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

Is the latest Phasor Components 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 Phasor Components for US stocks?

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