Title

• bug: Error in displaying different cryptocurrencies

Short Description:

• I am trying to select a crypto to view its prices live, which I use binance.websockets.depthCache. The problem is that when I want to change to another crypto, I link both at once.

Platform:

• Windows

node version:

• 10.5.0

Long descrption

• I am trying to select a crypto to view its prices live, which I use binance.websockets.depthCache. The problem is that when I want to change to another crypto, I link both at once. I add, that when visualizing in the html, I see the two intertwined in the same field.

code

binance.websockets.depthCache([coin], (symbol, depth) => {
        let bids = binance.sortBids(depth.bids);
        let asks = binance.sortAsks(depth.asks);
        demanda = binance.first(bids);
        oferta = binance.first(asks);
        socket.emit('preuoferta', {number: oferta});
        socket.broadcast.emit('preuoferta', {number: oferta});
        socket.emit('preudemanda', {number: demanda});
        socket.broadcast.emit('preudemanda', {number: demanda});
      }); 

result

**I add, that when visualizing in the html, I see the two intertwined in the same field.**

Thank you very much and sorry for the inconvenience

I add:

I'm trying to do it with the prevDay, and closing the connection and neither.

Example: binance.websockets.terminate ('ethbtc @ ticker');

Answer: ['WebSocket closed: ethbtc @ ticker (1006)']

But the same thing keeps happening to me,

Thank you.

I can not reproduce your issue, sorry. Here is what I do:

1. Subscribe to websocket depth cache for the symbols you are interested in
2. Write to json every update
3. View json files in your webserver

binance.websockets.depthCache(['BTCUSDT', 'BNBBTC'], (symbol, depth) => {
    const limit = 500;
        // Note: 'cumulative' is meant for drawing a depth chart, remove if you want it just like the order book
    let bids = binance.sortBids(depth.bids, limit, 'cumulative');
    let asks = binance.sortAsks(depth.asks, limit, 'cumulative');
    console.log(bids,asks);
    //console.log(symbol+" depth cache update");
    //console.log("best bid: "+binance.first(bids));
    //console.log("best ask: "+binance.first(asks));
    //let output = {bids:binance.array(bids), asks:binance.array(asks)};
    //console.log(symbol,output);

    // save information to json file
    fs.writeFile("json/depth/"+symbol+".json", JSON.stringify(output, null, 4), (err)=>{});
});

Using prevDay to get information on all symbols

binance.prevDay(false, (error, prevDay) => {
    for ( let obj of prevDay ) {
        let symbol = obj.symbol;
        console.log(symbol+" volume:"+obj.volume+" change: "+obj.priceChangePercent+"%");
    }
    fs.writeFile("json/prevDay.json", JSON.stringify(prevDay, null, 4), (err)=>{});
});
