feat: 集成稳定性优化和自动恢复机制

主要改进:
- 保证金管理: 阈值75%,减仓30%,检查间隔5秒
- WebSocket恢复: 指数退避重连,致命错误自动退出
- 余额检测: 下单前检查,连续失败自动暂停
- 自动重启: Shell脚本和PM2双重保障
- 健康检查: 定时监控系统状态

新增功能:
- yarn trade:auto - 自动重启监控
- yarn trade:pm2 - PM2进程管理
- yarn health - 健康检查
- yarn positions - 仓位检查
- yarn reduce - 紧急减仓

优化配置:
- config/trading-strategy.json - 更激进的保护参数
- ecosystem.config.js - PM2完整配置
- scripts/auto-restart.sh - Shell监控脚本
- scripts/health-check.js - 健康检查脚本
- docs/OPTIMIZATION_GUIDE.md - 完整使用文档

经过13小时运行测试,解决了WebSocket 502崩溃和余额不足问题

+# Pacifica Delta中性交易系统 - 优化集成指南
+
+## 🚀 已实施的优化
+
+### 1. 保证金管理优化 ✅
+- **阈值调整**: 75% (原85%),更早介入防止爆仓
+- **减仓比例**: 30% (原20%),更快释放保证金
+- **检查间隔**: 5秒 (原10秒),更快响应市场变化
+
+**配置文件**: `config/trading-strategy.json`
+```json
+"dynamicPositionAdjustment": {
+  "maxMarginUsageThreshold": 0.75,
+  "targetMarginRelease": 0.3,
+  "checkInterval": 5000
+}
+```
+
+### 2. WebSocket错误恢复机制 ✅
+- **指数退避重连**: 避免频繁重试造成资源浪费
+- **致命错误处理**: 502/503错误自动退出进程,等待外部重启
+- **连续失败保护**: 连续5次失败后退出进程
+
+**实现文件**: `src/services/PacificaWebSocket.ts`
+- 最大重连次数: 100次
+- 基础延迟: 5秒,指数增长至最大60秒
+- 添加随机抖动防止同时重连
+
+### 3. 余额不足检测和暂停机制 ✅
+- **预先检查**: 下单前检查账户余额
+- **智能暂停**: 连续5次余额不足自动暂停60秒
+- **缓冲保护**: 保留10%余额缓冲
+
+**实现文件**: `scripts/run-delta-neutral-simple.ts`
+```typescript
+checkAccountBalance() // 余额检查
+handleInsufficientBalance() // 处理余额不足
+```
+
+### 4. 自动重启脚本 ✅
+
+#### 方式1: Shell脚本
+```bash
+# 启动自动重启监控
+yarn trade:auto
+
+# 功能特性:
+- 进程崩溃自动重启
+- 无输出超时检测(5分钟)
+- 连续失败延长等待时间
+- 最大重启100次
+```
+
+#### 方式2: PM2进程管理(推荐)
+```bash
+# 安装PM2
+npm install -g pm2
+
+# 启动交易程序
+yarn trade:pm2
+
+# 停止程序
+yarn trade:pm2:stop
+
+# 查看日志
+yarn trade:pm2:logs
+
+# 监控面板
+yarn trade:pm2:monitor
+```
+
+**PM2优势**:
+- 内存超过2G自动重启
+- 指数退避重启策略
+- 完整的日志管理
+- Web监控面板
+- 集群模式支持
+
+### 5. 健康检查系统 ✅
+```bash
+# 运行健康检查
+yarn health
+
+# PM2定时健康检查(每分钟)
+# 自动配置在ecosystem.config.js中
+```
+
+**检查项目**:
+- 日志文件活动状态
+- 交易统计和错误率
+- 内存使用情况
+- 自动告警通知(需配置Webhook)
+
+## 📊 运维命令汇总
+
+### 基础命令
+```bash
+# 正常启动交易
+yarn trade
+
+# 自动重启模式
+yarn trade:auto
+
+# PM2管理模式
+yarn trade:pm2
+
+# 检查仓位
+yarn positions
+
+# 紧急减仓
+yarn reduce
+
+# 清理订单
+yarn cleanup-orders
+
+# 健康检查
+yarn health
+```
+
+### PM2管理命令
+```bash
+# 启动所有服务
+pm2 start ecosystem.config.js
+
+# 重启服务
+pm2 restart delta-neutral-trading
+
+# 查看状态
+pm2 status
+
+# 查看日志
+pm2 logs
+
+# 监控CPU/内存
+pm2 monit
+
+# 保存进程列表
+pm2 save
+
+# 设置开机自启
+pm2 startup
+```
+
+## 🔧 配置优化建议
+
+### 1. 生产环境配置
+```json
+// config/trading-strategy.json
+{
+  "orderStrategy": {
+    "preferredOrderType": "market", // 市价单保证成交
+    "checkInterval": 10
+  },
+  "positions": {
+    "balanceUsageRatio": 0.8, // 使用80%余额
+    "basePositionRatio": 0.2,  // 20%基础仓位
+    "volumePositionRatio": 0.8 // 80%刷量仓位
+  },
+  "dynamicPositionAdjustment": {
+    "enabled": true,
+    "maxMarginUsageThreshold": 0.75,
+    "targetMarginRelease": 0.3,
+    "checkInterval": 5000
+  },
+  "retry": {
+    "maxAttempts": 3,
+    "delayMs": 10000,
+    "apiCallInterval": 2000
+  }
+}
+```
+
+### 2. 监控配置
+```bash
+# 设置告警Webhook(Slack/Discord)
+export ALERT_WEBHOOK_URL="https://hooks.slack.com/services/xxx"
+
+# 启动监控
+yarn trade:pm2
+```
+
+## 🚨 故障处理
+
+### WebSocket 502错误
+- **自动处理**: 系统会自动重连,超过限制后退出
+- **手动处理**: 重启服务 `yarn trade:pm2:stop && yarn trade:pm2`
+
+### 余额不足错误
+- **自动处理**: 暂停60秒后自动恢复
+- **手动处理**: 充值账户或运行 `yarn reduce` 减仓
+
+### 保证金告警
+- **自动处理**: 自动减仓30%释放保证金
+- **手动处理**: 运行 `yarn reduce` 紧急减仓
+
+### 进程崩溃
+- **PM2模式**: 自动重启,最多100次
+- **Shell模式**: 运行 `yarn trade:auto`
+
+## 📈 性能监控
+
+### 查看实时状态
+```bash
+# PM2监控面板
+yarn trade:pm2:monitor
+
+# 查看日志
+tail -f logs/trading.log
+
+# 查看统计
+cat logs/stats.json | jq '.'
+
+# 查看健康状态
+cat logs/health.json | jq '.'
+```
+
+### 关键指标
+- **保证金使用率**: < 75%
+- **错误率**: < 10%
+- **内存使用**: < 2GB
+- **日志更新**: < 5分钟
+
+## 🔄 更新和维护
+
+### 更新配置
+1. 编辑 `config/trading-strategy.json`
+2. 重启服务: `pm2 restart delta-neutral-trading`
+
+### 更新代码
+```bash
+# 拉取最新代码
+git pull
+
+# 重新构建
+yarn build
+
+# 重启服务
+pm2 restart ecosystem.config.js
+```
+
+### 备份数据
+```bash
+# 备份日志
+cp -r logs/ logs_backup_$(date +%Y%m%d)/
+
+# 备份配置
+cp -r config/ config_backup_$(date +%Y%m%d)/
+```
+
+## 📞 支持
+
+遇到问题请检查:
+1. 日志文件: `logs/trading.log`
+2. 健康状态: `logs/health.json`
+3. PM2状态: `pm2 status`
+4. 系统资源: `top` 或 `htop`
