FAQ

Find answers to common questions about this symbol and its data.

What is the latest price of KOSDAQ Composite Index (KOSDAQ)?

KOSDAQ Composite Index (KOSDAQ) last traded at 827.12 , up +5.14 (+0.63%) from the previous close of 821.98, as of 2026-09-17. The price on this page updates once per trading day after the session closes. For a live quote, use the REST endpoint or WebSocket stream in the API playground above.

How do I get real-time KOSDAQ data from an API?

POST the Infoway REST endpoint at data.infoway.io/common/v2/batch_kline. Put your API key in the request header, and send a JSON body with codes=KOSDAQ, klineType (1-minute through yearly), and klineNum. It returns the latest OHLCV bars for KOSDAQ — open, high, low, close, volume, and percent change. Enter KOSDAQ and your key in the REST tab of the playground above to see the full request and response.

How do I get historical OHLCV data for KOSDAQ?

Use the same kline endpoint with a daily interval and a bar count, and it returns up to that many daily candles for KOSDAQ ending at the latest completed session. Each candle carries a Unix timestamp, open/high/low/close, volume, and turnover. For intraday history, change the interval to minutes or hours; for a fixed date window, filter the returned candles by timestamp. The playground above generates ready-to-run KOSDAQ samples in Java, Go, Python, JavaScript, PHP, and cURL.

How do I stream live KOSDAQ prices over WebSocket?

Open a connection to the Infoway WebSocket endpoint, authenticate with your API key, and send a subscribe message listing KOSDAQ. You then receive a push on every bar update for KOSDAQ with price, size, and timestamp. A single connection can subscribe to many symbols at once. The WebSocket tab in the playground above has a runnable example pre-filled with KOSDAQ.
