Get Kline/candlestick data for a symbol

You can use the optional API parameters for getting historical candlesticks, these are useful if you want to import data from earlier back in time. Optional parameters: limit (max/default 500), startTime, endTime.

// Intervals: 1m,3m,5m,15m,30m,1h,2h,4h,6h,8h,12h,1d,3d,1w,1M
binance.candlesticks("BNBBTC", "5m", (error, ticks, symbol) => {
  console.info("candlesticks()", ticks);
  let last_tick = ticks[ticks.length - 1];
  let [time, open, high, low, close, volume, closeTime, assetVolume, trades, buyBaseVolume, buyAssetVolume, ignored] = last_tick;
  console.info(symbol+" last close: "+close);
}, {limit: 500, endTime: 1514764800000});

WebSockets Implementation

Get Complete WebSocket Chart Cache

This function pulls existing chart data before connecting to the WebSocket, and provides you realtime synchronized chart information including the most recent 500 candles.

binance.websockets.chart("BNBBTC", "1m", (symbol, interval, chart) => {
  let tick = binance.last(chart);
  const last = chart[tick].close;
  console.info(chart);
  // Optionally convert 'chart' object to array:
  // let ohlc = binance.ohlc(chart);
  // console.info(symbol, ohlc);
  console.info(symbol+" last price: "+last)
});

Troubleshooting

Verify that your system time is correct. If you have any suggestions don't hesitate to file an issue.

Having problems? Try adding useServerTime to your options or setting recvWindow:

binance.options({
  APIKEY: 'xxx',
  APISECRET: 'xxx',
  useServerTime: true,
  recvWindow: 60000, // Set a higher recvWindow to increase response timeout
  verbose: true, // Add extra output when subscribing to WebSockets, etc
  log: log => {
    console.log(log); // You can create your own logger here, or disable console output
  }
});

Problems getting your balance? Wrap the entry point of your application in useServerTime:

await binance.useServerTime();
binance.balance((error, balances) => {
    if ( error ) return console.error(error);
    console.info("balances()", balances);
    console.info("BNB balance: ", balances.BNB.available);
});

You can enable verbose mode to help with debugging WebSocket streams:

binance.setOption( 'verbose', true );
