  • For buys: Uses 50% of virtual SOL reserves
  • For sells: Uses 50% of available token balance

Safety Features

• Transaction validation and simulation
• Automatic token account creation
• Balance checks before execution
• Comprehensive error handling and logging

Logging System

• Colored output for different message types
• Transaction counting and tracking
• Detailed timing information
• Multiple log levels (DEBUG, INFO, ERROR, SUCCESS, WARNING)
