How It Works

Based on TradingView's WebSocket protocol (unofficial API):

• Connect to wss://data.tradingview.com/socket.io/websocket
• Subscribe to symbol quotes and indicators
• Receive realtime updates

Usage

Get Realtime Quote

import { TradingViewClient } from './tradingview-client';

const tv = new TradingViewClient();
await tv.connect();

// Subscribe to Bitcoin price
tv.subscribeQuote('BINANCE:BTCUSDT', (data) => {
  console.log(`BTC: $${data.lp} (${data.ch > 0 ? '+' : ''}${data.chp}%)`);
});

// Get multiple symbols
tv.subscribeQuotes(['NASDAQ:AAPL', 'NASDAQ:TSLA', 'FX:EURUSD']);

Get Indicator Values

// Get RSI value for any timeframe
const rsi = await tv.getIndicator('BINANCE:BTCUSDT', 'RSI', {
  timeframe: '1H',
  length: 14
});
console.log(`RSI(14): ${rsi.value}`);

// Get multiple indicators
const indicators = await tv.getIndicators('BINANCE:BTCUSDT', [
  { name: 'RSI', params: { length: 14 } },
  { name: 'MACD', params: { fast: 12, slow: 26, signal: 9 } },
  { name: 'EMA', params: { length: 50 } },
  { name: 'BB', params: { length: 20, stdDev: 2 } }
]);

Screener Data

// Get top gainers from crypto screener
const gainers = await tv.getScreener('crypto', {
  sort: { sortBy: 'change', sortOrder: 'desc' },
  filter: { change: { gte: 5 } },
  limit: 20
});

// Stock screener with custom filter
const stocks = await tv.getScreener('america', {
  filter: {
    'market_cap_basic': { gte: 1e9 },
    'RSI': { lte: 30 },
    'change': { lte: -5 }
  },
  columns: ['name', 'close', 'change', 'volume', 'RSI', 'market_cap_basic']
});
