What is ROC?

Rate of Change measures the percentage change between the current close and the close n candles ago. It makes moves comparable across symbols of any price.

ROC formula

Output	Calculation
ROC	(close − close n ago) ÷ close n ago × 100

How to read ROC in your code

Signal	Meaning	Condition
Rising	Price above level n candles ago	`value` > 0
Falling	Price below level n candles ago	`value` < 0
Zero cross	Momentum flipped	`value` changes sign

Limitations: It compares only two points, so whichever candle sits at the far end of the window can distort the reading. Nothing on this page is financial advice.

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

Get ROC for multiple symbols

Combine ROC 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 ROC 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.

ROC API FAQ

What does the ROC API return?

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

Is the latest ROC 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 ROC settings can I change?

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

Can I get ROC for US stocks?

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

What is the difference between ROC, ROCP and ROCR?

roc is a percentage (5 for +5%), rocp is a fraction (0.05), rocr is a ratio (1.05) and rocr100 is that ratio times 100 (105).
