2. Binance API Integration

Binance provides excellent APIs for both historical and real-time cryptocurrency data. Here's how to implement a robust data fetching system:

Historical Data Fetcher

// services/binanceAPI.js
import axios from 'axios';

class BinanceAPI {
    constructor() {
        this.baseURL = 'https://api.binance.com/api/v3';
        this.wsURL = 'wss://stream.binance.com:9443/ws';
    }

    // Fetch historical kline data
    async getKlineData(symbol, interval, limit = 1000) {
        try {
            const response = await axios.get(`${this.baseURL}/klines`, {
                params: {
                    symbol: symbol.toUpperCase(),
                    interval: interval,
                    limit: limit
                }
            });

            return response.data.map(kline => ({
                time: kline[0] / 1000, // Convert to seconds
                open: parseFloat(kline[1]),
                high: parseFloat(kline[2]),
                low: parseFloat(kline[3]),
                close: parseFloat(kline[4]),
                volume: parseFloat(kline[5])
            }));
        } catch (error) {
            console.error('Error fetching kline data:', error);
            throw error;
        }
    }

    // Get current price
    async getCurrentPrice(symbol) {
        try {
            const response = await axios.get(`${this.baseURL}/ticker/price`, {
                params: { symbol: symbol.toUpperCase() }
            });
            return parseFloat(response.data.price);
        } catch (error) {
            console.error('Error fetching current price:', error);
            throw error;
        }
    }

    // Get 24h price change statistics
    async get24hrStats(symbol) {
        try {
            const response = await axios.get(`${this.baseURL}/ticker/24hr`, {
                params: { symbol: symbol.toUpperCase() }
            });
            return {
                priceChange: parseFloat(response.data.priceChange),
                priceChangePercent: parseFloat(response.data.priceChangePercent),
                volume: parseFloat(response.data.volume),
                high: parseFloat(response.data.highPrice),
                low: parseFloat(response.data.lowPrice)
            };
        } catch (error) {
            console.error('Error fetching 24hr stats:', error);
            throw error;
        }
    }
}

export default new BinanceAPI();

Real-time WebSocket Connection

// hooks/useWebSocket.js
import { useEffect, useRef, useState } from 'react';
import ReconnectingWebSocket from 'reconnecting-websocket';

export const useWebSocket = (symbol, interval, onMessage) => {
    const ws = useRef(null);
    const [connectionStatus, setConnectionStatus] = useState('Disconnected');

    useEffect(() => {
        if (!symbol) return;

        const wsUrl = `wss://stream.binance.com:9443/ws/${symbol.toLowerCase()}@kline_${interval}`;
        
        ws.current = new ReconnectingWebSocket(wsUrl, [], {
            maxReconnectionDelay: 10000,
            minReconnectionDelay: 1000,
            reconnectionDelayGrowFactor: 1.3,
            connectionTimeout: 4000,
            maxRetries: Infinity,
            debug: false
        });

        ws.current.onopen = () => {
            console.log('WebSocket Connected');
            setConnectionStatus('Connected');
        };

        ws.current.onmessage = (event) => {
            try {
                const data = JSON.parse(event.data);
                if (data.k) {
                    const kline = {
                        time: data.k.t / 1000,
                        open: parseFloat(data.k.o),
                        high: parseFloat(data.k.h),
                        low: parseFloat(data.k.l),
                        close: parseFloat(data.k.c),
                        volume: parseFloat(data.k.v),
                        isFinal: data.k.x
                    };
                    onMessage(kline);
                }
            } catch (error) {
                console.error('Error parsing WebSocket message:', error);
            }
        };

        ws.current.onclose = () => {
            console.log('WebSocket Disconnected');
            setConnectionStatus('Disconnected');
        };

        ws.current.onerror = (error) => {
            console.error('WebSocket Error:', error);
            setConnectionStatus('Error');
        };

        return () => {
            if (ws.current) {
                ws.current.close();
            }
        };
    }, [symbol, interval, onMessage]);

    return { connectionStatus };
};

3. TradingView Chart Implementation

Now let's implement the core charting component using TradingView Lightweight Charts with professional styling and features:

Professional Chart Component

// components/TradingChart.jsx
import React, { useEffect, useRef, useState } from 'react';
import { createChart } from 'lightweight-charts';
import { useWebSocket } from '../hooks/useWebSocket';
import BinanceAPI from '../services/binanceAPI';

const TradingChart = ({ symbol = 'ETHUSDT', interval = '1m' }) => {
    const chartContainerRef = useRef();
    const chart = useRef();
    const candlestickSeries = useRef();
    const volumeSeries = useRef();
    const [isLoading, setIsLoading] = useState(true);

    // Chart configuration
    const chartOptions = {
        layout: {
            background: { color: '#1a1a2e' },
            textColor: '#d1d4dc',
        },
        grid: {
            vertLines: { color: '#2B2B43' },
            horzLines: { color: '#2B2B43' },
        },
        crosshair: {
            mode: 1,
        },
        rightPriceScale: {
            borderColor: '#485c7b',
        },
        timeScale: {
            borderColor: '#485c7b',
            timeVisible: true,
            secondsVisible: false,
        },
        watermark: {
            visible: true,
            fontSize: 24,
            horzAlign: 'center',
            vertAlign: 'center',
            color: 'rgba(171, 71, 188, 0.5)',
            text: 'CryptoChart',
        },
    };

    // Initialize chart
    useEffect(() => {
        if (!chartContainerRef.current) return;

        chart.current = createChart(chartContainerRef.current, {
            ...chartOptions,
            width: chartContainerRef.current.clientWidth,
            height: 500,
        });

        // Create candlestick series
        candlestickSeries.current = chart.current.addCandlestickSeries({
            upColor: '#26a69a',
            downColor: '#ef5350',
            borderVisible: false,
            wickUpColor: '#26a69a',
            wickDownColor: '#ef5350',
        });

        // Create volume series
        volumeSeries.current = chart.current.addHistogramSeries({
            color: '#26a69a',
            priceFormat: {
                type: 'volume',
            },
            priceScaleId: '',
            scaleMargins: {
                top: 0.8,
                bottom: 0,
            },
        });

        // Handle resize
        const handleResize = () => {
            if (chart.current && chartContainerRef.current) {
                chart.current.applyOptions({
                    width: chartContainerRef.current.clientWidth,
                });
            }
        };

        window.addEventListener('resize', handleResize);

        return () => {
            window.removeEventListener('resize', handleResize);
            if (chart.current) {
                chart.current.remove();
            }
        };
    }, []);

    // Load historical data
    useEffect(() => {
        const loadHistoricalData = async () => {
            try {
                setIsLoading(true);
                const data = await BinanceAPI.getKlineData(symbol, interval, 1000);
                
                if (candlestickSeries.current && volumeSeries.current) {
                    candlestickSeries.current.setData(data);
                    volumeSeries.current.setData(
                        data.map(item => ({
                            time: item.time,
                            value: item.volume,
                            color: item.close >= item.open ? '#26a69a' : '#ef5350'
                        }))
                    );
                }
            } catch (error) {
                console.error('Error loading historical data:', error);
            } finally {
                setIsLoading(false);
            }
        };

        loadHistoricalData();
    }, [symbol, interval]);

    // Handle real-time updates
    const handleRealtimeUpdate = (kline) => {
        if (candlestickSeries.current && volumeSeries.current) {
            candlestickSeries.current.update({
                time: kline.time,
                open: kline.open,
                high: kline.high,
                low: kline.low,
                close: kline.close,
            });

            volumeSeries.current.update({
                time: kline.time,
                value: kline.volume,
                color: kline.close >= kline.open ? '#26a69a' : '#ef5350'
            });
        }
    };

    // WebSocket connection
    const { connectionStatus } = useWebSocket(symbol, interval, handleRealtimeUpdate);

    return (
        <div className="relative">
            {isLoading && (
                <div className="absolute inset-0 flex items-center justify-center bg-gray-900/50 z-10">
                    <div className="text-white">Loading chart data...</div>
                </div>
            )}
            
            <div className="flex items-center justify-between mb-4">
                <h3 className="text-xl font-bold text-white">
                    {symbol.replace('USDT', '/USDT')} - {interval.toUpperCase()} Chart
                </h3>
                <div className={`px-3 py-1 rounded-full text-sm ${
                    connectionStatus === 'Connected'

            />
        </div>
    );
};

export default TradingChart;

4. Advanced Features and Indicators

Professional trading platforms require advanced features like technical indicators, multiple timeframes, and interactive controls:

Chart Controls Component

// components/ChartControls.jsx
import React from 'react';

const ChartControls = ({ 
    symbol, 
    setSymbol, 
    interval, 
    setInterval, 
    chartType, 
    setChartType 
}) => {
    const intervals = [
        { value: '1m', label: '1m' },
        { value: '5m', label: '5m' },
        { value: '15m', label: '15m' },
        { value: '30m', label: '30m' },
        { value: '1h', label: '1h' },
        { value: '4h', label: '4h' },
        { value: '1d', label: '1D' },

        { value: 'line', label: 'Line' },
        { value: 'area', label: 'Area' }
    ];

    const popularSymbols = [
        'BTCUSDT', 'ETHUSDT', 'BNBUSDT', 'ADAUSDT', 
        'DOTUSDT', 'XRPUSDT', 'LTCUSDT', 'LINKUSDT'
    ];

            </div>

            {/* Interval Selector */}
            <div className="flex items-center gap-2">

                        >
                            {int.label}
                        </button>

                            key={type.value}
                            onClick={() => setChartType(type.value)}
                            className={`px-3 py-2 text-sm rounded transition-colors ${
