What is ROCR?

ROCR returns the rate of change as a ratio: the current close divided by the close n candles ago. A value of 1 means no change.

ROCR formula

Output	Calculation
ROCR	Close ÷ close n ago

How to read ROCR in your code

Signal	Meaning	Condition
Higher than before	Price above level n candles ago	`value` > 1
Lower than before	Price below level n candles ago	`value` < 1

Limitations: It shares ROC's dependence on a single earlier candle. Nothing on this page is financial advice.

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

Get ROCR for multiple symbols

Combine ROCR 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.

ROCR API FAQ

What does the ROCR API return?

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

Is the latest ROCR 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 ROCR settings can I change?

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

Can I get ROCR for US stocks?

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