TradingView Realtime Data

Get realtime market prices, indicators, and screener data from TradingView without official API.

Features

• Realtime Prices: WebSocket streaming for any TradingView symbol
• Indicators: Get values from any indicator (RSI, MACD, MAs, custom)
• Screener Data: Access TradingView stock/crypto screeners
• Chart Data: Historical OHLCV data
• No API Key Required: Uses public TradingView data

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']
});

Historical Data

// Get OHLCV bars
const bars = await tv.getBars('BINANCE:BTCUSDT', {
  timeframe: '1D',
  from: Date.now() - 30 * 24 * 60 * 60 * 1000, // 30 days
  to: Date.now()
});

Integration with K.I.T.

Market Analysis Skill

// Get comprehensive market overview
const analysis = await kit.skills.tradingviewRealtime.analyze('BINANCE:BTCUSDT');
// Returns: { price, indicators, trend, support, resistance }

Signal Generation

// Use TradingView indicators for signals
kit.on('tradingview:indicator', (data) => {
  if (data.symbol === 'BTCUSDT' && data.RSI < 30) {
    kit.emit('signal:buy', { symbol: data.symbol, reason: 'RSI oversold' });
  }
});

Multi-Source Confirmation

// Combine with exchange data for confirmation
const tvPrice = await tv.getQuote('BINANCE:BTCUSDT');
const exchangePrice = await binance.getPrice('BTCUSDT');
const slippage = Math.abs(tvPrice.lp - exchangePrice) / exchangePrice * 100;

Rate Limits & Best Practices

• Max ~50 symbol subscriptions per connection
• Use batch requests where possible
• Cache indicator values (update every few seconds, not milliseconds)
• Implement reconnection logic for connection drops
• Don't hammer the WebSocket (1 request per 100ms minimum)

Resources

• TradingView-API (GitHub)
• Apify TradingView Scraper
