Inverse Contracts

Rest client

const {RestClient} = require('bybit-api');

const API_KEY = 'xxx';
const PRIVATE_KEY = 'yyy';

const client = new RestClient(API_KEY, PRIVATE_KEY);

client.changeUserLeverage({leverage: 4, symbol: 'ETHUSD'})
  .then(result => {
    console.log(result);
  })
  .catch(err => {
    console.error(err);
  });

See inverse rest-client.js for further information.

Websocket client

const {WebsocketClient} = require('bybit-api');

const API_KEY = 'xxx';
const PRIVATE_KEY = 'yyy';

const ws = new WebsocketClient({key: API_KEY, secret: PRIVATE_KEY});

ws.subscribe(['position', 'execution', 'trade']);
ws.subscribe('kline.BTCUSD.1m');

ws.on('open', () => {
  console.log('connection open');
});

ws.on('update', message => {
  console.log('update', message);
});

ws.on('response', response => {
  console.log('response', response);
});

ws.on('close', () => {
  console.log('connection closed');
});

ws.on('error', err => {
  console.error('ERR', err);
});

See inverse websocket-client.js & ws api docs for further information.

Customise Logging

Pass a custom logger which supports the log methods silly, debug, notice, info, warning and error, or override methods from the default logger as desired:

const { RestClient, WebsocketClient, DefaultLogger } = require('bybit-api');

// Disable all logging on the silly level
DefaultLogger.silly = () => {};

const ws = new WebsocketClient({key: 'xxx', secret: 'yyy'}, DefaultLogger);
