Live Data Stream

Stay ahead in the market with real-time updates using our Live Data Stream API. This feature empowers you to access live stock prices for all instruments supported by the getAllInstruments API. With every price change, your callback function will receive the updated tick, enabling you to make swift, informed decisions.

Key Features

Real-Time Updates: Get live stock prices and other critical data points as they happen.

Customizable Callbacks: Define how each tick should be processed in your application.

Flexible Integration: Easily integrate with both Node.js on the backend or React.js on the client side to save server cost.

How to Use

Node.js

await initialize("APIKEY", (tick) => {
    // Custom processing logic here
    console.log(tick);
});

unsubscribe = subscribe(instrumentTokens);

initialize: Initializes the live data stream with your API key and a callback function to handle each tick.

subscribe: Subscribes to updates for the specified instrument tokens. Example: subscribe([738561, ..])

React.js

await initialiseStocksEyes(
    "---GET YOUR API KEY---> https://stockseyes.com/contact",
    StocksEyesEnvironment.PRODUCTION
);

const unsubscribe = await subscribeRealTimeData(
    instrumentTokens,
    [Fields.TRADING_SYMBOL, Fields.LAST_PRICE, Fields.VOLUME, Fields.DEPTH, Fields.PREVIOUS_DEPTH, Fields.PREVIOUS_PRICE],
    (data) => {
        console.log(data);
        setTradableData(data); // set your states
    }
);

initialiseStocksEyes: Initializes the data stream with your API key and environment settings.

subscribeRealTimeData:(instrumentTokens, fields, callback): Subscribes to specific fields for real-time updates on the given instrument tokens. Use the returned unsubscribe function to stop receiving updates.

Example Response

Your callback will be called with array of live data of instruments continuously till it is subscribed
