+# TradingView Automation - Credential Usage
+
+## Overview
+
+You now have **two ways** to provide TradingView credentials:
+
+### Method 1: Environment Variables (.env file) - Like the original
+```bash
+# In your .env file
+TRADINGVIEW_EMAIL=your-email@example.com
+TRADINGVIEW_PASSWORD=your-password
+```
+
+### Method 2: API Parameters - More flexible
+```json
+{
+  "symbol": "SOLUSD",
+  "timeframe": "5",
+  "credentials": {
+    "email": "your-email@example.com", 
+    "password": "your-password"
+  }
+}
+```
+
+## Usage Examples
+
+### 1. Using .env credentials (like original tradingview.ts)
+
+```bash
+# Set in .env file first
+echo "TRADINGVIEW_EMAIL=your-email@example.com" >> .env
+echo "TRADINGVIEW_PASSWORD=your-password" >> .env
+
+# Then call API without credentials
+curl -X POST http://localhost:3000/api/trading/automated-analysis \
+  -H "Content-Type: application/json" \
+  -d '{
+    "symbol": "SOLUSD",
+    "timeframe": "5"
+  }'
+```
+
+### 2. Using API parameters (more secure for multi-user)
+
+```bash
+curl -X POST http://localhost:3000/api/trading/automated-analysis \
+  -H "Content-Type: application/json" \
+  -d '{
+    "symbol": "SOLUSD",
+    "timeframe": "5",
+    "credentials": {
+      "email": "user1@example.com",
+      "password": "password1"
+    }
+  }'
+```
+
+### 3. Programmatic usage
+
+```typescript
+import { enhancedScreenshotService } from './lib/enhanced-screenshot'
+
+// Method 1: Using .env (no credentials needed)
+const screenshots1 = await enhancedScreenshotService.captureWithLogin({
+  symbol: 'SOLUSD',
+  timeframe: '5'
+  // credentials will be read from .env automatically
+})
+
+// Method 2: Explicit credentials
+const screenshots2 = await enhancedScreenshotService.captureWithLogin({
+  symbol: 'SOLUSD', 
+  timeframe: '5',
+  credentials: {
+    email: 'user@example.com',
+    password: 'password'
+  }
+})
+```
+
+## Key Differences from Original
+
+| Feature | tradingview.ts (Original) | tradingview-automation.ts (New) |
+|---------|---------------------------|----------------------------------|
+| Framework | Puppeteer | Playwright |
+| Credentials | Only .env | .env OR parameters |
+| Usage | Complex layouts | Simple AI analysis |
+| Video Recording | ✅ Yes | ❌ No |
+| Code Size | 777 lines | ~400 lines |
+| Docker Optimized | ✅ Yes | ✅ Yes |
+| Debug Screenshots | ✅ Extensive | ✅ Basic |
+
+## Priority Order for Credentials
+
+1. **API parameters** (if provided)
+2. **Environment variables** (.env file)
+3. **Error** if neither is available
+
+## Security Considerations
+
+- **Environment variables**: Good for single-user setups
+- **API parameters**: Better for multi-user applications
+- **Never commit credentials** to git repositories
+- Use `.env.local` for local development
+
+## Migration from Original
+
+If you're currently using the original `tradingview.ts`:
+
+1. **Keep using .env**: No changes needed, just call the new API
+2. **Switch to parameters**: More flexible, supports multiple users
+3. **Hybrid approach**: Use .env as fallback, parameters for specific users
