What is CMO?

The Chande Momentum Oscillator, from Tushar Chande, compares the sum of up moves with the sum of down moves over a window. Unlike RSI it uses unsmoothed sums and ranges from −100 to +100.

CMO formula

Output	Calculation
CMO	100 × (sum of up moves − sum of down moves) ÷ (sum of up moves + sum of down moves)

How to read CMO in your code

Signal	Meaning	Condition
Overbought	Up moves dominate strongly	`value` above 50
Oversold	Down moves dominate strongly	`value` below −50
Bias	Momentum direction	`value` above or below 0

Limitations: Because it is unsmoothed it is jumpier than RSI, and a single large candle leaving the window can shift it abruptly. Nothing on this page is financial advice.

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

Get CMO for multiple symbols

Combine CMO 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.

CMO API FAQ

What does the CMO API return?

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

Is the latest CMO 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 CMO settings can I change?

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

Can I get CMO for US stocks?

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

Which parameter sets the CMO length?

Use optInTimePeriod. It defaults to 14.
