Basic Real-time Data Streaming

import asyncio
from tvkit.api.chart.ohlcv import OHLCV

async def stream_bitcoin():
    async with OHLCV() as client:
        # Stream real-time OHLCV data for Bitcoin
        count = 0
        async for bar in client.get_ohlcv("BINANCE:BTCUSDT", interval="1"):
            count += 1
            print(f"Bar {count}: BTC ${bar.close:,.2f} | Volume: {bar.volume:,.0f}")
            
            # Limit demo to 5 bars
            if count >= 5:
                break

asyncio.run(stream_bitcoin())

Sample Output:

Bar 1: BTC $43,250.50 | Volume: 125,430
Bar 2: BTC $43,275.25 | Volume: 98,750
Bar 3: BTC $43,290.75 | Volume: 156,890
Bar 4: BTC $43,245.00 | Volume: 134,200
Bar 5: BTC $43,267.50 | Volume: 145,600

Historical Data & Export

import asyncio
from tvkit.api.chart.ohlcv import OHLCV
from tvkit.export import DataExporter
from tvkit.api.utils import convert_timestamp_to_iso

async def fetch_and_export_apple_data():
    # Fetch historical Apple stock data
    async with OHLCV() as client:
        bars = await client.get_historical_ohlcv(
            "NASDAQ:AAPL",
            interval="1D",  # Daily bars
            bars_count=30   # Last 30 days
        )
    
    print(f"📊 Fetched {len(bars)} daily bars for Apple")
    print(f"📅 Date range: {convert_timestamp_to_iso(bars[0].timestamp)[:10]} to {convert_timestamp_to_iso(bars[-1].timestamp)[:10]}")
    
    # Show first 3 bars
    print("\n🔍 First 3 bars:")
    for i, bar in enumerate(bars[:3]):
        date = convert_timestamp_to_iso(bar.timestamp)[:10]
        print(f"  {date}: Open=${bar.open:.2f}, High=${bar.high:.2f}, Low=${bar.low:.2f}, Close=${bar.close:.2f}, Volume={bar.volume:,.0f}")
    
    # Export to multiple formats
    exporter = DataExporter()
    
    # Export to Polars DataFrame with technical analysis
    df = await exporter.to_polars(bars, add_analysis=True)
    print(f"\n📈 DataFrame created: {df.shape[0]} rows × {df.shape[1]} columns")
    print(f"Columns: {', '.join(df.columns[:8])}...")
    
    # Export to files
    json_path = await exporter.to_json(bars, "./export/apple_data.json", include_metadata=True)
    csv_path = await exporter.to_csv(bars, "./export/apple_data.csv", include_metadata=True)
    
    print(f"\n💾 Exported to:")
    print(f"   JSON: {json_path}")
    print(f"   CSV: {csv_path}")
    
    return df

asyncio.run(fetch_and_export_apple_data())

Sample Output:

📊 Fetched 30 daily bars for Apple
📅 Date range: 2024-06-15 to 2024-07-15

🔍 First 3 bars:

🏗️ Architecture

tvkit is built with three main components:

1. 📡 Real-Time Chart API (tvkit.api.chart)

• WebSocket Streaming: Live market data with minimal latency
• OHLCV Data: Open, High, Low, Close, Volume with timestamps
• Quote Data: Real-time price updates and market information
• Multiple Symbols: Stream data from multiple assets simultaneously

from tvkit.api.chart.ohlcv import OHLCV

# Stream multiple symbols
async with OHLCV() as client:
    symbols = ["BINANCE:BTCUSDT", "NASDAQ:AAPL", "FOREX:EURUSD"]
    async for info in client.get_latest_trade_info(symbols):
        print(f"Trade info: {info}")

Multi-Market Stock Scanner

import asyncio
from tvkit.api.scanner import ScannerService, Market, MarketRegion
from tvkit.api.scanner import create_comprehensive_request, ColumnSets, get_markets_by_region

async def scan_asian_markets():
    service = ScannerService()
    
    # Create comprehensive request for top stocks by market cap
    request = create_comprehensive_request(
        sort_by="market_cap_basic",
        sort_order="desc",
        range_end=5  # Top 5 stocks per market
    )
    
    # Scan specific Asian markets
    markets_to_scan = [Market.THAILAND, Market.JAPAN, Market.SINGAPORE]
    
    print("🌏 Scanning Asian Markets for Top Stocks by Market Cap")
    print("=" * 60)
    
    for market in markets_to_scan:
        print(f"\n📊 Scanning {market.value.title()} market...")
        
        response = await service.scan_market(market, request)
        print(f"✅ Found {len(response.data)} stocks")
        
        if response.data:
            top_stock = response.data[0]  # Market leader
            print(f"\n🏆 Market Leader:")
            print(f"   Symbol: {top_stock.name}")
            print(f"   Price: {top_stock.close} {top_stock.currency}")
            if top_stock.market_cap_basic:
                print(f"   Market Cap: ${top_stock.market_cap_basic:,.0f}")
            if top_stock.price_earnings_ttm:
                print(f"   P/E Ratio: {top_stock.price_earnings_ttm:.2f}")
            print(f"   Sector: {top_stock.sector or 'N/A'}")
    
    # Regional analysis
    print(f"\n🌍 Regional Analysis - Asia Pacific Markets:")
    asia_markets = get_markets_by_region(MarketRegion.ASIA_PACIFIC)
    print(f"Total Asia Pacific markets available: {len(asia_markets)}")
    
    return response.data

asyncio.run(scan_asian_markets())
