🏗️ Architecture Overview

1. Separation of Concerns

• Demo Trading: Safe environment for testing strategies without financial risk
• Real Trading: Protected environment with real money trading capabilities
• Web Interface: Centralized control and monitoring dashboard
• Bot Manager: Process-based management to avoid threading issues

2. Security Implementation

• Real trading credentials are gitignored and protected
• Demo environment isolated from real trading
• Environment-specific configurations
• Process isolation for safety

3. Technology Stack

• Backend: Python 3.x with MT5 integration
• Web Framework: Flask for dashboard
• Process Management: Subprocess for bot isolation
• Real-time Communication: WebSocket-like updates via file monitoring

🔧 Technical Implementation

MT5 Integration

# Key MT5 functions used:
mt5.initialize()           # Initialize MT5 connection
mt5.login()               # Authenticate with broker
mt5.symbol_info()         # Get symbol information
mt5.order_send()          # Execute trades
mt5.account_info()        # Get account details

Process-Based Architecture

• Why Process-Based?: Avoids Python's GIL limitations and threading issues
• Benefits:
  • True parallel execution
  • Isolated memory spaces
  • Crash isolation
  • Better resource management

Web Interface Features

• Real-time Monitoring: Live account balance and trade updates
• Bot Control: Start/stop bots remotely
• Manual Trading: Execute trades through web interface
• Log Viewing: Real-time log monitoring
• Responsive Design: Works on desktop and mobile
