+### Docker Volume Mount Troubleshooting & Direct Container Development
 **Common Issue**: File edits not reflecting in container due to volume mount sync issues.
 
-**Solutions:**
+**Container-First Development Workflow:**
+For immediate results and faster iteration, edit files directly inside the running container first, then rebuild for persistence:
+
+```bash
+# 1. Access running container for immediate edits
+docker compose -f docker-compose.dev.yml exec app bash
+
+# 2. Edit files directly in container (immediate effect)
+# Use nano, vi, or echo for quick changes
+nano /app/lib/enhanced-screenshot.ts
+echo "console.log('Debug: immediate test');" >> /app/debug.js
+
+# 3. Test changes immediately (no rebuild needed)
+# Changes take effect instantly for hot reload
+
+# 4. Once everything works, copy changes back to host
+docker cp container_name:/app/modified-file.js ./modified-file.js
+
+# 5. Commit successful changes to git BEFORE rebuilding
+git add .
+git commit -m "feat: implement working solution for [specific feature]"
+git push origin development
+
+# 6. Rebuild container for persistence
+docker compose -f docker-compose.dev.yml down
+docker compose -f docker-compose.dev.yml up --build -d
+
+# 7. Final validation and commit completion
+# Test that changes persist after rebuild
+curl http://localhost:9001  # Verify functionality
+git add . && git commit -m "chore: confirm container persistence" && git push
+```
+
+**Alternative Solutions:**
 1. **Fresh Implementation Approach**: When modifying existing files fails, create new files (e.g., `page-v2.js`) instead of editing corrupted files
 2. **Container Restart**: `docker compose -f docker-compose.dev.yml restart app`
 3. **Full Rebuild**: `docker compose -f docker-compose.dev.yml down && docker compose -f docker-compose.dev.yml up --build`

-### TradingView Automation Patterns
+### Browser Process Management & Cleanup System
+**Critical Issue**: Chromium processes accumulate during automated trading, consuming system resources over time.
+
+**Robust Cleanup Implementation:**
+The trading bot includes a comprehensive cleanup system to prevent Chromium process accumulation:
+
+**Core Cleanup Components:**
+1. **Enhanced Screenshot Service** (`lib/enhanced-screenshot-robust.ts`)
+   - Guaranteed cleanup via `finally` blocks in all browser operations
+   - Active session tracking to prevent orphaned browsers
+   - Session cleanup tasks array for systematic teardown
+
+2. **Automated Cleanup Service** (`lib/automated-cleanup-service.ts`)
+   - Background monitoring service for orphaned processes
+   - Multiple kill strategies: graceful → force → system cleanup
+   - Periodic cleanup of temporary files and browser data
+
+3. **Aggressive Cleanup Utilities** (`lib/aggressive-cleanup.ts`)
+   - System-level process killing for stubborn Chromium processes
+   - Port cleanup and temporary directory management
+   - Emergency cleanup functions for resource recovery
+
+**Implementation Patterns:**
+```typescript
+// Always use finally blocks for guaranteed cleanup
+try {
+  const browser = await puppeteer.launch(options);
+  // ... browser operations
+} finally {
+  // Guaranteed cleanup regardless of success/failure
+  await ensureBrowserCleanup(browser, sessionId);
+  await cleanupSessionTasks(sessionId);
+}
+
+// Background monitoring for long-running operations
+const cleanupService = new AutomatedCleanupService();
+cleanupService.startPeriodicCleanup(); // Every 10 minutes
+```
+
+**Cleanup Testing:**
+```bash
+# Test cleanup system functionality
+node test-cleanup-system.js
+
+# Monitor Chromium processes during automation
+watch 'pgrep -f "chrome|chromium" | wc -l'
+
+# Manual cleanup if needed
+node -e "require('./lib/aggressive-cleanup.ts').performAggressiveCleanup()"
+```
+
+**Prevention Strategies:**
+- Use session tracking for all browser instances
+- Implement timeout protection for long-running operations
+- Monitor resource usage during extended automation cycles
+- Restart containers periodically for fresh environment

+### Cleanup System Architecture
+**Critical Production Issue**: Chromium processes accumulate during automated trading, leading to resource exhaustion after several hours of operation.
+
+**Solution Components:**
+1. **Enhanced Screenshot Service** (`lib/enhanced-screenshot-robust.ts`)
+   - Replaces original screenshot service with guaranteed cleanup
+   - Uses `finally` blocks to ensure browser cleanup regardless of success/failure
+   - Active session tracking with cleanup task arrays
+   - Force-kill functionality for stubborn processes
+
+2. **Automated Cleanup Service** (`lib/automated-cleanup-service.ts`)
+   - Background monitoring service that runs every 10 minutes
+   - Multiple cleanup strategies: graceful → force → system-level cleanup
+   - Temporary file cleanup and browser data directory management
+   - Orphaned process detection and elimination
+
+3. **Aggressive Cleanup Utilities** (`lib/aggressive-cleanup.ts`)
+   - Emergency cleanup functions for critical resource recovery
+   - System-level process management with multiple kill strategies
+   - Port cleanup and zombie process elimination
+   - Used by both automated service and manual intervention
+
+**Integration Pattern:**
+```typescript
+// In API routes - always use finally blocks
+app/api/enhanced-screenshot/route.js:
+try {
+  const result = await enhancedScreenshot.captureAndAnalyze(...);
+  return NextResponse.json(result);
+} finally {
+  // Guaranteed cleanup execution
+  await enhancedScreenshot.cleanup();
+}
+
+// Background monitoring
+lib/automated-cleanup-service.ts:
+setInterval(async () => {
+  await this.performCleanup();
+}, 10 * 60 * 1000); // Every 10 minutes
+```
+
+**Testing Cleanup System:**
+```bash
+# Monitor process count during operation
+watch 'pgrep -f "chrome|chromium" | wc -l'
+
+# Test cleanup functionality
+node test-cleanup-system.js
+
+# Manual cleanup if needed
+docker compose exec app node -e "require('./lib/aggressive-cleanup.ts').forceKillAllChromium()"

+
+## Common Issues & Troubleshooting
+
+### Chromium Process Accumulation
+**Symptoms**: System becomes slow after hours of automation, high CPU/memory usage, many chrome processes running
+**Diagnosis**: `pgrep -f "chrome|chromium" | wc -l` shows increasing process count
+**Solutions**:
+1. Ensure all browser automation uses finally blocks for cleanup
+2. Restart automated cleanup service: `docker compose exec app node -e "require('./lib/automated-cleanup-service.ts').startPeriodicCleanup()"`
+3. Manual cleanup: `docker compose exec app node test-cleanup-system.js`
+4. Container restart: `docker compose restart app`
+
+### Volume Mount Sync Issues
+**Symptoms**: File changes not reflecting in running container
+**Diagnosis**: Edit test file and check if visible in container
+**Solutions**:
+1. **Quick Fix**: Edit directly in container for immediate testing
+2. **Commit Progress**: Save working changes to git before rebuilding
+3. **Persistence**: Always rebuild container after confirming changes work
+4. **Final Commit**: Validate and commit after successful rebuild
+5. **Manual Copy**: Use `docker cp` to transfer working files
+6. **Fresh Start**: Create new files instead of editing problematic ones
+
+### Automation Page Restoration
+**Symptoms**: Automation page shows old version after container rebuild
+**Issue**: Git history not properly maintained in container
+**Solutions**:
+1. Check current branch: `git branch`
+2. Restore from git: `git checkout HEAD -- app/automation-v2/page.js`
+3. Verify features: Check for balance slider and multi-timeframe selection
+4. Commit restoration: `git add . && git commit -m "fix: restore automation-v2 functionality" && git push`
+5. Rebuild container to persist restoration
+
+### Successful Implementation Workflow
+**After completing any feature or fix:**
+```bash
+# 1. Test functionality thoroughly
+curl http://localhost:9001/api/test-endpoint
+
+# 2. Commit successful implementation
+git add .
+git commit -m "feat: [specific achievement] - fully tested and working"
+git push origin development
+
+# 3. Rebuild container for persistence  
+docker compose down && docker compose up --build -d
+
+# 4. Final validation and completion commit
+curl http://localhost:9001  # Verify persistent functionality
+git add . && git commit -m "chore: confirm [feature] persistence - implementation complete" && git push
+
+# 5. Consider merge to main if ready for production
+# (Ask user first before merging to main branch)
+```
+
+### API Endpoint Not Responding
+**Symptoms**: API calls timeout or return errors
+**Diagnosis**: Check container logs: `docker compose logs -f app`
+**Solutions**:
+1. Verify container is running: `docker ps`
+2. Check port mapping: Development=9001:3000, Production=9000:3000
+3. Test direct access: `curl localhost:9001/api/status`
+4. Restart if needed: `docker compose restart app`
