Web Socket Issues

perceptron

@Moderator_1 I am using smart api for creating a live data feed for stock prices on my site. I am using live websocket streaming service. But issue is in javascript sdk prices of almost 400-500 stocks are received 0. I also tried quote mode but still no success. Can you tell me what could be the issue?

const getConnection = async () => {
      db = await spp.find({});
      var array = db.map(obj => obj.token);
      var bbb = array.slice(1000,);
      const rtg = await aaaa();
      abc(bbb, rtg);
  };
  
module.exports = getConnection;

function abc(array, data) {
  const web_socket = new WebSocketV2({
    jwttoken: data.jwtToken,
    apikey: 'API_KEY',
    clientcode: "CLIENT_CODE",
    feedtype: data.feedToken,
  });

  web_socket.connect().then((res) => {
    let json_req = {
      "correlationID": "abcde12345",
      "action": 1,
      "mode": 2,
      "exchangeType": 1,
      "tokens": array
    };

    web_socket.fetchData(json_req);
    web_socket.on('tick', receiveTick);
    var x = 0;
    async function receiveTick(data) {
      if (data.token !== undefined) {
        
        const io = getIO();
        const tokenWithQuotes = data.token;
        const tokenWithoutQuotes = tokenWithQuotes.replace(/['"]+/g, '');
        
        const price = parseInt(data.last_traded_price, 10) / 100;
        // console.log(tokent_to_stock[tokenWithoutQuotes],price);
        if(price == 0) {
          x++;
          console.log(tokent_to_stock[tokenWithoutQuotes], x);
        }
          io.to(tokent_to_stock[tokenWithoutQuotes]).emit('update', {
            stock: tokent_to_stock[tokenWithoutQuotes],
            price: price
          });

          await spp.updateOne(
            { token: tokenWithoutQuotes },
            [{
              $set: {
                previousprice: "$currentprice",
                currentprice: price
              }
            }]
          );
      }
    }
  });
}

this is my code.

@Moderator_2 @Moderator_1 Is there any update please i need this.

@perceptron I think there is some issue with websockets when more number of tokens are subscribed. I facing a similar problem where I am subscribing to 200 tokens and I am observing delays in receiving ticks.

@perceptron @Moderator_1 @Moderator_2 is there any update?

@Moderator_2 @Moderator_1 is there any progress on this issue?

@Moderator_2 I am initiating 2 sockets basically with first socket having 0 to 1000 NSE stocks and other having the rest. I do not think that should be much of an issue because even when i am initiating request with only one socket and one stock this error persists.

HI @perceptron

We are verifying on the issue. Will update you asap.
Please check if the websocket connection is initiated within limit (three connection only allowed per client code).
