+# NoFX Trading Bot - PM2 Deployment Guide
+
+Complete guide for local development and production deployment using PM2.
+
+## 🚀 Quick Start
+
+### 1. Install PM2
+
+```bash
+npm install -g pm2
+```
+
+### 2. One-Command Launch
+
+```bash
+./pm2.sh start
+```
+
+That's it! Frontend and backend will start automatically.
+
+---
+
+## 📋 All Commands
+
+### Service Management
+
+```bash
+# Start services
+./pm2.sh start
+
+# Stop services
+./pm2.sh stop
+
+# Restart services
+./pm2.sh restart
+
+# View status
+./pm2.sh status
+
+# Delete services
+./pm2.sh delete
+```
+
+### Log Viewing
+
+```bash
+# View all logs (live)
+./pm2.sh logs
+
+# Backend logs only
+./pm2.sh logs backend
+
+# Frontend logs only
+./pm2.sh logs frontend
+```
+
+### Build & Compile
+
+```bash
+# Compile backend
+./pm2.sh build
+
+# Recompile backend and restart
+./pm2.sh rebuild
+```
+
+### Monitoring
+
+```bash
+# Open PM2 monitoring dashboard (real-time CPU/Memory)
+./pm2.sh monitor
+```
+
+---
+
+## 📊 Access URLs
+
+After successful startup:
+
+- **Frontend Web Interface**: http://localhost:3000
+- **Backend API**: http://localhost:8080
+- **Health Check**: http://localhost:8080/api/health
+
+---
+
+## 🔧 Configuration Files
+
+### pm2.config.js
+
+PM2 configuration file, defines frontend and backend startup parameters:
+
+```javascript
+const path = require('path');
+
+module.exports = {
+  apps: [
+    {
+      name: 'nofx-backend',
+      script: './nofx',           // Go binary
+      cwd: __dirname,             // Dynamically get current directory
+      autorestart: true,
+      max_memory_restart: '500M'
+    },
+    {
+      name: 'nofx-frontend',
+      script: 'npm',
+      args: 'run dev',            // Vite dev server
+      cwd: path.join(__dirname, 'web'), // Dynamically join path
+      autorestart: true,
+      max_memory_restart: '300M'
+    }
+  ]
+};
+```
+
+**After modifying configuration, restart is required:**
+```bash
+./pm2.sh restart
+```
+
+---
+
+## 📝 Log File Locations
+
+- **Backend Logs**: `./logs/backend-error.log` and `./logs/backend-out.log`
+- **Frontend Logs**: `./web/logs/frontend-error.log` and `./web/logs/frontend-out.log`
+
+---
+
+## 🔄 Startup on Boot
+
+Set PM2 to start on boot:
+
+```bash
+# 1. Start services
+./pm2.sh start
+
+# 2. Save current process list
+pm2 save
+
+# 3. Generate startup script
+pm2 startup
+
+# 4. Follow the instructions to execute command (requires sudo)
+```
+
+**Disable startup on boot:**
+```bash
+pm2 unstartup
+```
+
+---
+
+## 🛠️ Common Operations
+
+### Restart After Code Changes
+
+**Backend changes:**
+```bash
+./pm2.sh rebuild  # Auto compile and restart
+```
+
+**Frontend changes:**
+```bash
+./pm2.sh restart  # Vite will auto hot-reload, no restart needed
+```
+
+### View Real-time Resource Usage
+
+```bash
+./pm2.sh monitor
+```
+
+### View Detailed Information
+
+```bash
+pm2 info nofx-backend   # Backend details
+pm2 info nofx-frontend  # Frontend details
+```
+
+### Clear Logs
+
+```bash
+pm2 flush
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### Service Startup Failed
+
+```bash
+# 1. View detailed errors
+./pm2.sh logs
+
+# 2. Check port usage
+lsof -i :8080  # Backend port
+lsof -i :3000  # Frontend port
+
+# 3. Manual compile test
+go build -o nofx
+./nofx
+```
+
+### Backend Won't Start
+
+```bash
+# ~~Check if config.json exists~~
+# ~~ls -l config.json~~
+
+# Check if database file exists
+ls -l trading.db
+
+# Check permissions
+chmod +x nofx
+
+# Run manually to see errors
+./nofx
+```
+
+### Frontend Not Accessible
+
+```bash
+# Check node_modules
+cd web && npm install
+
+# Manual start test
+npm run dev
+```
+
+---
+
+## 🎯 Production Environment Recommendations
+
+### 1. Use Production Mode
+
+Modify `pm2.config.js`:
+
+```javascript
+{
+  name: 'nofx-frontend',
+  script: 'npm',
+  args: 'run preview',  // Change to preview (requires npm run build first)
+  env: {
+    NODE_ENV: 'production'
+  }
+}
+```
+
+### 2. Increase Instances (Load Balancing)
+
+```javascript
+{
+  name: 'nofx-backend',
+  script: './nofx',
+  instances: 2,  // Start 2 instances
+  exec_mode: 'cluster'
+}
+```
+
+### 3. Auto Restart Strategy
+
+```javascript
+{
+  autorestart: true,
+  max_restarts: 10,
+  min_uptime: '10s',
+  max_memory_restart: '500M'
+}
+```

+## 📦 Comparison with Docker Deployment
+
+| Feature | PM2 Deployment | Docker Deployment |
+|---------|---------------|-------------------|
+| Startup Speed | ⚡ Fast | 🐌 Slower |
+| Resource Usage | 💚 Low | 🟡 Medium |
+| Isolation | 🟡 Medium | 💚 High |
+| Use Case | Dev/Single-machine | Production/Cluster |
+| Configuration Complexity | 💚 Simple | 🟡 Medium |
+
+**Recommendations:**
+- **Development Environment**: Use `./pm2.sh`
+- **Production Environment**: Use `./start.sh` (Docker)
