Embedding TradingView Charting Library: A Technical Guide

Building a trading platform? You can either create a custom charting engine (3–6 months) or embed TradingView Advanced Charts. It's the industry standard, used by Binance, Coinbase, and others. Our team has done 50+ integrations; we know the pitfalls. This guide covers integration steps and common errors. The most frequent error: timestamp units. History endpoint uses seconds, realtime callbacks use milliseconds. This mistake can cause missing data and weeks of debugging. None. None. None. None. None.

None: Preparing a Datafeed

TradingView doesn't fetch data itself—your platform must implement the UDF API. This protocol includes four endpoints: /config, /symbols, /search, /history. None. Here's an example FastAPI implementation:

from fastapi import FastAPI import uvicorn app = FastAPI() @app.get("/config") def get_config(): return {"supports_search": True, "supports_group_request": False, "supports_marks": False, "supports_timescale_marks": False, "exchanges": [{"value": "", "name": "All Exchanges", "desc": ""}]} @app.get("/symbols") def get_symbols(symbol: str): # Return symbol info return {"symbol": symbol, "ticker": symbol, "name": symbol, "description": "", "type": "crypto", "session": "24x7", "exchage": "Crypto", "listed_exchange": "Crypto", "timezone": "Etc/UTC", "has_intraday": True, "has_weekly_and_monthly": False, "has_no_volume": False, "currency_code": "USD", "pricescale": 100, "minmov": 1, "fractional": False} @app.get("/search") def search_symbols(query: str, limit: int = 30): # Return search results return [{"symbol": "BTCUSD", "full_name": "BTCUSD", "description": "Bitcoin / USD", "exchange": "Crypto", "ticker": "BTCUSD", "type": "crypto"}] @app.get("/history") def get_history(symbol: str, resolution: str, from: int, to: int): # Return OHLCV data return {"s": "ok", "t": [1625097600], "o": [35000], "h": [35500], "l": [34800], "c": [35200], "v": [1000]} if __name__ == "__main__": uvicorn.run(app, host="0.0.0.0", port=8000) 

None. None. None. (Local entities: None, None, None, None, None.)

None: WebSocket Real-Time Updates

For live data, the datafeed must push updates via WebSocket. The onRealtimeCallback expects milliseconds. None.

None: Custom Indicators and Broker Integration

TradingView supports custom studies via Pine Script. You can also integrate broker API for order placement. None.

None: Conclusion

None. None. None. None. None. The key is to avoid timestamp mismatch. Our service handles this and more. None. (Local entities: None, None, None, None, None.)
