TradingView Automation - Credential Usage

Overview

You now have two ways to provide TradingView credentials:

Method 1: Environment Variables (.env file) - Like the original

# In your .env file
TRADINGVIEW_EMAIL=your-email@example.com
TRADINGVIEW_PASSWORD=your-password

Method 2: API Parameters - More flexible

{
  "symbol": "SOLUSD",
  "timeframe": "5",
  "credentials": {
    "email": "your-email@example.com", 
    "password": "your-password"
  }
}

Usage Examples

1. Using .env credentials (like original tradingview.ts)

# 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)

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

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

API parameters (if provided)
Environment variables (.env file)
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:

Keep using .env: No changes needed, just call the new API
Switch to parameters: More flexible, supports multiple users
Hybrid approach: Use .env as fallback, parameters for specific users
