环境安装与配置

安装CCXT库

# Node.js
npm install ccxt

# Python
pip install ccxt

# PHP
composer require ccxt/ccxt

基础配置示例

const ccxt = require('ccxt');

// 创建交易平台实例
const exchange = new ccxt.binance({
    apiKey: 'YOUR_API_KEY',
    secret: 'YOUR_SECRET_KEY',
    timeout: 30000,
    enableRateLimit: true,
    options: {
        defaultType: 'spot', // 指定现货交易
    }
});

市场数据获取

加载交易对信息

async function loadMarkets() {
    try {
        await exchange.loadMarkets();
        console.log('市场加载成功');
        
        // 获取所有交易对
        const symbols = exchange.symbols;
        console.log(`共加载 ${symbols.length} 个交易对`);
        
        // 获取BTC/USDT交易对信息
        const btcusdt = exchange.markets['BTC/USDT'];
        console.log('BTC/USDT交易对信息:', btcusdt);
        
    } catch (error) {
        console.error('市场加载失败:', error.message);
    }
}

实时行情数据获取

async function getMarketData() {
    try {
        // 获取单个交易对行情
        const ticker = await exchange.fetchTicker('BTC/USDT');
        console.log('BTC/USDT行情:', {
            last: ticker.last,      // 最新价
            bid: ticker.bid,        // 买一价
            ask: ticker.ask,        // 卖一价
            volume: ticker.quoteVolume // 成交量
        });
        
        // 获取订单簿
        const orderbook = await exchange.fetchOrderBook('BTC/USDT');
        console.log('买盘前5档:', orderbook.bids.slice(0, 5));
        console.log('卖盘前5档:', orderbook.asks.slice(0, 5));
        
    } catch (error) {
        console.error('获取行情数据失败:', error.message);
    }
}

账户管理与资金查询

查询账户余额

async function getBalance() {
    try {
        const balance = await exchange.fetchBalance();
        
        console.log('总资产概览:');
        console.log('USDT余额:', balance.USDT?.free || 0);
        console.log('BTC余额:', balance.BTC?.free || 0);
        
        // 详细资产列表
        const total = balance.total;
        Object.keys(total).forEach(currency => {
            if (total[currency] > 0) {
                console.log(`${currency}: ${total[currency]}`);
            }
        });
        
    } catch (error) {
        console.error('查询余额失败:', error.message);
    }
}

订单操作完整流程

创建限价单

async function createLimitOrder() {
    try {
        const symbol = 'BTC/USDT';
        const type = 'limit';
        const side = 'buy';  // 买入
        const amount = 0.001; // 数量
        const price = 50000;  // 价格
        
        const order = await exchange.createOrder(symbol, type, side, amount, price);
        
        console.log('订单创建成功:', {
            id: order.id,
            status: order.status,
            filled: order.filled,
            remaining: order.remaining
        });
        
        return order.id;
        
    } catch (error) {
        console.error('创建订单失败:', error.message);
        throw error;
    }
}

创建市价单

async function createMarketOrder() {
    try {
        const symbol = 'BTC/USDT';
        const type = 'market';
        const side = 'buy';
        const amount = 0.001; // 购买金额(对于市价单)
        
        const order = await exchange.createOrder(symbol, type, side, amount);
        
        console.log('市价单创建成功:', order);
        return order.id;
        
    } catch (error) {
        console.error('市价单创建失败:', error.message);
        throw error;
    }
}

查询订单状态

async function checkOrderStatus(orderId) {
    try {
        const order = await exchange.fetchOrder(orderId, 'BTC/USDT');
        
        console.log('订单状态:', {
            id: order.id,
            status: order.status,
            symbol: order.symbol,

        console.log('撤单成功:', result);
        return result;
        
    } catch (error) {
        console.error('撤单失败:', error.message);
        throw error;
    }
}

批量订单查询与管理

        console.log('最近成交订单:', closedOrders.length);
        
        return { openOrders, closedOrders };
        
    } catch (error) {
        console.error('查询订单列表失败:', error.message);
        throw error;
    }
}

完整交易策略示例

简单的网格交易策略

class GridTradingStrategy {
    constructor(exchange, symbol, gridLevels, investment) {
        this.exchange = exchange;
        this.symbol = symbol;
        this.gridLevels = gridLevels;
        this.investment = investment;
        this.orders = [];
    }
    
    async initialize() {
        await this.exchange.loadMarkets();
        this.ticker = await this.exchange.fetchTicker(this.symbol);
        this.currentPrice = this.ticker.last;
        
        console.log(`当前价格: ${this.currentPrice}`);
        this.calculateGridLevels();
    }
    
    calculateGridLevels() {
        const priceRange = this.currentPrice * 0.1; // 10%价格区间
        this.levels = [];
        
        for (let i = 0; i < this.gridLevels; i++) {
            const buyPrice = this.currentPrice - (priceRange / this.gridLevels) * (i + 1);
            const sellPrice = this.currentPrice + (priceRange / this.gridLevels) * (i + 1);
            
            this.levels.push({
                buyPrice: parseFloat(buyPrice.toFixed(2)),
                sellPrice: parseFloat(sellPrice.toFixed(2)),
                amount: this.investment / this.gridLevels / this.currentPrice
            });
        }
        
        console.log('网格等级计算完成:', this.levels);
    }
    
    async placeGridOrders() {
        for (const level of this.levels) {
            try {
                // 放置买入限价单
                const buyOrder = await this.exchange.createOrder(
                    this.symbol,
                    'limit',
                    'buy',
                    level.amount,
                    level.buyPrice
                );
                
                this.orders.push(buyOrder);
                console.log(`买入订单放置成功: ${level.buyPrice}`);
                
            } catch (error) {
                console.error(`放置买入订单失败: ${error.message}`);
            }
        }
    }
    
    async monitorOrders() {
        setInterval(async () => {
            try {
                const openOrders = await this.exchange.fetchOpenOrders(this.symbol);
                const filledOrders = this.orders.filter(order => 
                    !openOrders.some(open => open.id === order.id)
                );
                
                // 处理已成交订单
                for (const filledOrder of filledOrders) {
                    console.log(`订单 ${filledOrder.id} 已成交`);
                    // 这里可以添加止盈逻辑
                }
                
            } catch (error) {
                console.error('监控订单失败:', error.message);
            }
        }, 30000); // 每30秒检查一次
    }
}

错误处理与最佳实践

健壮的错误处理机制

class TradingBot {
    constructor(exchange) {
        this.exchange = exchange;
        this.maxRetries = 3;
        this.retryDelay = 1000;
    }
    
    async withRetry(operation, ...args) {
        for (let attempt = 1; attempt <= this.maxRetries; attempt++) {
            try {
                return await operation.apply(this.exchange, args);
            } catch (error) {
                console.warn(`尝试 ${attempt} 失败:`, error.message);
                
                if (attempt === this.maxRetries) {
                    throw error;
                }
                
                // 指数退避重试
                await new Promise(resolve => 
                    setTimeout(resolve, this.retryDelay * Math.pow(2, attempt - 1))
                );
            }
        }
    }
    
    async safeCreateOrder(...args) {
        return this.withRetry(this.exchange.createOrder, ...args);
    }
    
    async safeFetchBalance() {
        return this.withRetry(this.exchange.fetchBalance);
    }
}

速率限制管理

CCXT内置了速率限制功能,但需要正确配置:

// 启用速率限制
const exchange = new ccxt.binance({
    apiKey: 'YOUR_API_KEY',
    secret: 'YOUR_SECRET_KEY',
    enableRateLimit: true,
    rateLimit: 1000, // 自定义速率限制(毫秒)
});

// 手动处理速率限制
exchange.throttle().then(() => {
    // 确保不超过速率限制
    return exchange.fetchTicker('BTC/USDT');
});
