What is Hyperbolic Tangent?

Hyperbolic Tangent is a math function that applies the hyperbolic tangent, which squashes values to between −1 and 1. On TAAPI.IO it runs on the candles you request, so you can get the result without doing the calculation on your side.

Limitations: On raw prices it saturates at 1. It is useful for normalised inputs. Nothing on this page is financial advice.

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

Get Hyperbolic Tangent for multiple symbols

Combine Hyperbolic Tangent 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.

Hyperbolic Tangent API FAQ

What does the Hyperbolic Tangent API return?

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

Is the latest Hyperbolic Tangent 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 Hyperbolic Tangent for US stocks?

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