What is Hyperbolic Cosine?

Hyperbolic Cosine is a math function that applies the hyperbolic cosine. On TAAPI.IO it runs on the candles you request, so you can get the result without doing the calculation on your side.

Output	cosh(x)

Result	Function output for the candle	`value`

Limitations: It grows exponentially, so large inputs overflow. Expect unusable values on raw prices. Nothing on this page is financial advice.

Read Hyperbolic Cosine from Python

Use backtrack=1 to read the result as of the last closed candle.

curl -G https://v2.taapi.io/indicator/cosh \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "backtrack=1"

import requests

resp = requests.get(
    'https://v2.taapi.io/indicator/cosh',
    headers={'Authorization': 'Bearer YOUR_API_KEY'},
    params={'exchange': 'binance', 'symbol': 'BTCUSDT', 'timeframe': '1h', 'backtrack': 1},
)
data = resp.json()
print(data['value'])

Get historical Hyperbolic Cosine 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/cosh \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "exchange=binance" \
  --data-urlencode "symbol=BTCUSDT" \
  --data-urlencode "timeframe=1h" \
  --data-urlencode "results=100"

Get Hyperbolic Cosine for multiple symbols

Combine Hyperbolic Cosine 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 Cosine API FAQ

What does the Hyperbolic Cosine API return?

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

Is the latest Hyperbolic Cosine 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 Cosine for US stocks?

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