TradingView Scraper for Node.js

Really basic TradingView data scraper for Node.js.
warning: the implementation is a little bit dirty, but hey, it works!

Installation

npm i tradingview-scraper --save

Featuring

real-time data freshly ~~stolen~~ borrowed from TradingView's socket.io interface
almost 100% success rate of ~~stealing~~ borrowing data
1:1 accuracy of ~~stolen~~ borrowed data #confirmed
HTTP Origin header spoofing so nobody will notice anything suspicious
okay, let's finally go into the serious mode, shall we?

Constructor

const TradingViewAPI = require('tradingview-scraper');
const tv = new TradingViewAPI();

new TradingViewAPI()

In order to request data from TradingView using this library, you need to instantiate a new object of TradingViewAPI. The constructor does not accept any parameters, and starts handling connection to TradingView's servers out of the box.

Methods

List of all available methods for TradingViewAPI.

getTicker(ticker)

Loads the data about ticker from TradingView.

Parameters:

ticker is a ticker name, either 'pro' or 'short'

Returns a Promise which when resolved returns an object representing the current data for ticker on TradingView, for example:

{ last_retrieved: 2018-09-04T14:07:06.909Z,
  ask: 0.8671,
  bid: 0.8666,
  s: 'ok',
  last_update: 2018-09-04T14:07:06.902Z,
  ch: 0.0058,
  chp: 0.67,
  current_session: 'market',
  description: 'U.S. DOLLAR / EURO',
  exchange: 'FX_IDC',
  fractional: false,
  high_price: 0.867,
  is_tradable: true,
  low_price: 0.8607,
  lp: 0.8666,
  minmov: 1,
  minmove2: 1,
  open_price: 0.8607,
  original_name: 'FX_IDC:USDEUR',
  prev_close_price: 0.8608,
  pricescale: 10000,
  pro_name: 'FX_IDC:USDEUR',
  short_name: 'USDEUR',
  type: 'forex',
  update_mode: 'streaming',
  volume: 0 }

The Promise may be rejected if the request was timed out.
warning: The request will timeout if the ticker does not exist on TradingView. That is an expected behavior.
