Can you please provide working example of websocket order status? Just like you have one for ebsocket streaming.

Please proovide working example, not link to the existing documentation.

Thanks!

Hello Team,
I'm trying to connect websocket via node sdk I tried both the old and new ways defined in this file,

https://github.com/angel-one/smartapi-javascript

Error message Im getting,

D:\user\node\jupiter-trader\node_modules\smartapi-javascript\lib\websocket2.0.js:89
                                                                throw new Error(evt.message);
                                                                ^

Below is the sample code I'm trying to do,

async function connectWebSocket() {
    try {
        const web_socket = new WebSocketV2({
            jwttoken: smart_api.access_token, // response from loginAPI
            apikey: smart_api.api_key, // response from loginAPI
            clientcode: 'K518180', // my client codo
            feedtype: 'market_feed',
        });

        console.log('🔄 Connecting with WebSocketV2...');
         // Set up event handlers BEFORE connecting
        web_socket.on('open', () => {
            console.log('✅ WebSocketV2 connected successfully');
        });
        web_socket.on('tick', (data) => {
            console.log('📈 Market data received:', data);
            // Process market data for your trading logic
            // data will contain ltp, volume, etc.
        });
        web_socket.on('error', (err) => {
            console.error('❌ WebSocketV2 error:', err.message);
            if (err.message.includes('401')) {
                console.error('⚠️ Authentication failed! JWT token may be invalid or expired.');
                console.error('Get a fresh JWT token from generateSession()');
            }
        });
        web_socket.on('close', () => {
            console.log('🔌 WebSocketV2 connection closed');
            // Attempt reconnect after delay
            setTimeout(() => {
                console.log('Attempting to reconnect...');
                connectWebSocket();
            }, 5000);
        });

        // Connect
        console.log('🔄 Establishing WebSocketV2 connection...');
        await web_socket.connect();
        console.log('✅ WebSocketV2 connection established');


        // Use the format from documentation
        const json_req = {
            correlationID: 'order_monitor_' + Date.now(),
            action: 1,  // 1 = subscribe, 0 = unsubscribe
            mode: 1,
            exchangeType: 1,
            tokens: ["market_feed"],  // For order feed
        };

        web_socket.fetchData(json_req);

        web_socket.on('tick', (data) => {
            console.log('📦 Order update:', data);
        });

        web_socket.on('error', (err) => {
            console.error('WebSocketV2 error:', err);
        });

        return web_socket;

    } catch (error) {
        console.error('WebSocketV2 connection failed:', error);

        return;
    }

}

Can you please provide working example of websocket order status? Just like you have one for ebsocket streaming.

Please proovide working example, not link to the existing documentation.

Thanks!

Exactly.

@admin, Is this understanding correct?

If so, can we expect this functionality any time soon?

Regards,

I know that the websocket feed has the dp field to get market depth. But that gives a continuous feed.

I want to get the depth of a script at a point in time. Not as a feed.

So a single API call, with the scrip code and the dp task so that I get the depth of the stock at that instant.

Is it possible?

@admin

My client is is D184330 and number is 9769497239. Thanks!

I have a question regarding the update process for the mw task and dp task.

I want to know when a new feed from these tasks get generated. So basically, in any stock, there are 2 events

1. A trade happening (when trade happens automatically order book also changes)
2. Order book changes, without a trade

So I want to know when a new feed gets generated for the mw task and the dp task. The reason for the question is that in the mw response, there is best buy and best sell fields. So would a new entry get generated in teh mw feed even without a trade, but when best buy price changes?

The dp feed I guess would generate a new entry when any one of the 35 parameters in teh response changes.

So my question is quite simple. Would a new entry in mw feed get generated for a change in best buy/best sell without trade happening?

Regards,

@rajanprabu Thanks! Do share your experience.

Hi,

For the market feed, we can get feed of multiple scrip IDs by the & parameter. Is there a limit on the number of tokens I can put? Can I, for example, have 2000 tokens in one query?

More importanlty, would there be any performance issues with multiple tokens?

Regards,

Hi,

Could you please give more details on the web socket feed. Specifically, the task parameter.

1. What is the difference between mw, sfi and and dp.
2. What is the structure of the response in each of these fields

Would be great if some forum members elaborate on this.

Thanks!
