    double weekly_pnl;
    double monthly_pnl;
    double current_drawdown;
    double max_drawdown;
    int trades_today;
    double win_rate;

public:
    void UpdateMetrics();
    void DisplayDashboard();
    void SendDailyReport();
    void CheckAlerts();
    bool IsPerformanceAcceptable();
};
```

### 2. Log Management

#### Log Rotation Strategy

```bash
# Daily log rotation

- Compress archived logs
- Delete logs older than 30 days
- Monitor log file sizes
- Alert if log growth is excessive

# Log analysis
- Daily error count review
- Performance bottleneck identification
- Trade execution analysis
- System health monitoring
```

#### Log Analysis Script

```mql5
void AnalyzeLogs()
{
    // Count errors in last 24 hours
    int error_count = CountLogErrors(24);
    if(error_count > 10)
    {
        SendAlert("High error count: " + IntegerToString(error_count));
    }

    // Check performance metrics
    double avg_execution_time = GetAverageExecutionTime();
    if(avg_execution_time > 1000) // 1 second
    {
        SendAlert("Slow execution detected: " + DoubleToString(avg_execution_time) + "ms");
    }

    // Monitor memory usage
    long memory_usage = GetMemoryUsage();
    if(memory_usage > 500 * 1024 * 1024) // 500MB
    {
        SendAlert("High memory usage: " + IntegerToString(memory_usage / 1024 / 1024) + "MB");
    }
}
```

### 3. Automated Maintenance

#### Daily Maintenance Tasks

```mql5
void DailyMaintenance()
{
    // Clean up old chart objects
    CleanupChartObjects();

    // Archive old logs
    ArchiveOldLogs();

    // Update performance statistics
    UpdatePerformanceStats();

    // Check system health
    CheckSystemHealth();

    // Send daily report
    SendDailyReport();

    // Backup configuration
    BackupConfiguration();
}
```

#### Weekly Maintenance Tasks

## Troubleshooting

### 1. Common Issues and Solutions

#### EA Not Trading

**Symptoms**: EA attached but no trades executed
**Possible Causes**:

- Automated trading disabled
- Insufficient account balance
- Session filters too restrictive
- Risk parameters too conservative
- Market conditions not met

**Solutions**:

```mql5
// Check automated trading
if(!IsTradeAllowed())
{
    Print("Automated trading is disabled");
    // Enable in MT5: Tools -> Options -> Expert Advisors -> Allow automated trading
}

// Check account balance
if(AccountInfoDouble(ACCOUNT_BALANCE) < 1000)
{
    Print("Insufficient account balance for trading");
}

// Check session filters
if(!session_manager.CanOpenPosition())
{
    Print("Trading not allowed in current session");
    // Review session configuration
}

// Check risk parameters
if(RiskPercent < 0.1)
{
    Print("Risk percentage too low for meaningful trading");
}
```

#### High Memory Usage

**Symptoms**: MT5 consuming excessive memory
**Possible Causes**:

- Memory leaks in EA code
- Too many chart objects
- Large log files
- Inefficient data structures

**Solutions**:

```mql5
// Regular cleanup
void CleanupMemory()
{
    // Remove old chart objects
    ObjectsDeleteAll(0, "SniperEA_");

    // Clear old arrays
    ArrayFree(price_data);
    ArrayFree(indicator_buffer);

    // Force garbage collection
    Sleep(100);
}

// Monitor memory usage
void MonitorMemory()
{
    long memory_used = TerminalInfoInteger(TERMINAL_MEMORY_USED);
    if(memory_used > 500 * 1024 * 1024) // 500MB
    {
        Print("High memory usage detected: ", memory_used / 1024 / 1024, " MB");
        CleanupMemory();
    }
}
```

#### Poor Performance

**Symptoms**: EA running slowly or causing MT5 to freeze
**Possible Causes**:

- Inefficient algorithms
- Too frequent calculations
- Large datasets
- Network delays

**Solutions**:

```mql5
// Optimize calculations
void OptimizePerformance()
{
    // Cache expensive calculations
    static double cached_atr = 0;
    static datetime last_atr_calc = 0;

    if(TimeCurrent() - last_atr_calc > 3600) // Update hourly
    {
        cached_atr = iATR(Symbol(), Period(), 14);
        last_atr_calc = TimeCurrent();
    }

    // Use cached value
    double current_atr = cached_atr;
}

// Reduce calculation frequency
void ReduceCalculationFrequency()
{
    // Only calculate on new bar
    static datetime last_bar_time = 0;
    datetime current_bar_time = iTime(Symbol(), Period(), 0);

    if(current_bar_time != last_bar_time)
    {
        // Perform calculations
        PerformAnalysis();
        last_bar_time = current_bar_time;
    }
}
```

### 2. Error Codes and Messages

#### Common Error Codes

```mql5
// Trade execution errors
#define ERR_INVALID_TRADE_PARAMETERS    4051
#define ERR_TRADE_DISABLED              4109
#define ERR_NOT_ENOUGH_MONEY           4134

// Error handling function
void HandleError(int error_code)
{
    switch(error_code)
    {
        case ERR_NOT_ENOUGH_MONEY:
            Print("Insufficient funds for trade");
            // Reduce position size or stop trading
            break;

        case ERR_INVALID_STOPS:
            Print("Invalid stop loss or take profit levels");
            // Recalculate stop levels
            break;

        case ERR_MARKET_CLOSED:
            Print("Market is closed");
            // Wait for market to open
            break;

        default:
            Print("Unknown error: ", error_code);
            break;
    }
}
```

### 3. Diagnostic Tools

#### System Health Check

```mql5
bool SystemHealthCheck()
{
    bool health_ok = true;

    // Check MT5 connection
    if(!TerminalInfoInteger(TERMINAL_CONNECTED))
    {
        Print("ERROR: Terminal not connected to server");
        health_ok = false;
    }

    // Check account status
    if(AccountInfoInteger(ACCOUNT_TRADE_ALLOWED) == false)
    {
        Print("ERROR: Trading not allowed on account");
        health_ok = false;
    }

    // Check symbol availability
    if(!SymbolSelect(Symbol(), true))
    {
        Print("ERROR: Symbol not available: ", Symbol());
        health_ok = false;
    }

    // Check historical data
    int bars = Bars(Symbol(), Period());
    if(bars < 1000)
    {
        Print("WARNING: Insufficient historical data: ", bars, " bars");
    }

    return health_ok;
}
```

#### Performance Profiler

```mql5
class CPerformanceProfiler
{
private:
    ulong start_time;
    string function_name;

public:
    void StartProfiling(string func_name)
    {
        function_name = func_name;
        start_time = GetMicrosecondCount();
    }

    void EndProfiling()
    {
        ulong end_time = GetMicrosecondCount();
        ulong duration = end_time - start_time;

        if(duration > 10000) // 10ms threshold
        {
            Print("PERFORMANCE: ", function_name, " took ", duration, " microseconds");
        }
    }
};

// Usage example
CPerformanceProfiler profiler;
profiler.StartProfiling("AnalyzeEntry");
SEntrySignal signal = entry_strategy.AnalyzeEntry();
profiler.EndProfiling();
```

## Security Considerations

### 1. API Key Management

#### Secure API Key Storage

```mql5
// Never hardcode API keys in source code
// Use external configuration files or environment variables

class CSecureConfig
{
private:
    string encrypted_api_key;

public:
    bool LoadAPIKey(string config_file)
    {
        int file_handle = FileOpen(config_file, FILE_READ | FILE_TXT);
        if(file_handle == INVALID_HANDLE)
        {
            Print("Failed to open config file: ", config_file);
            return false;
        }

        // Read encrypted key
        encrypted_api_key = FileReadString(file_handle);
        FileClose(file_handle);

        return true;
    }

    string GetAPIKey()
    {
        // Decrypt and return API key
        return DecryptString(encrypted_api_key);
    }
};
```

#### API Key Rotation

```mql5
// Implement regular API key rotation
void RotateAPIKey()
{
    // Generate new API key
    string new_key = GenerateNewAPIKey();

    // Update configuration
    UpdateAPIKeyConfig(new_key);

    // Test new key
    if(TestAPIConnection(new_key))
    {
        // Activate new key
        SetActiveAPIKey(new_key);
        Print("API key rotated successfully");
    }
    else
    {
        Print("API key rotation failed");
    }
}
```

### 2. Data Protection

#### Sensitive Data Handling

```mql5
// Encrypt sensitive data before storage
class CDataProtection
{
public:
    static string EncryptData(string data, string key)
    {
        // Implement encryption algorithm
        // Use AES or similar strong encryption
        return encrypted_data;
    }

    static string DecryptData(string encrypted_data, string key)
    {
        // Implement decryption algorithm
        return decrypted_data;
    }

    static void SecureDelete(string filename)
    {
        // Overwrite file before deletion
        OverwriteFile(filename);
        FileDelete(filename);
    }
};
```

### 3. Access Control

#### User Authentication

```mql5
// Implement user authentication for EA access
class CAccessControl
{
private:
    string authorized_accounts[];
    datetime license_expiry;

public:
    bool IsAuthorized()
    {
        // Check account authorization
        long account_number = AccountInfoInteger(ACCOUNT_LOGIN);
        string account_str = IntegerToString(account_number);

        // Check if account is in authorized list
        for(int i = 0; i < ArraySize(authorized_accounts); i++)
        {
            if(authorized_accounts[i] == account_str)
            {
                return CheckLicenseValidity();
            }
        }

        return false;
    }

    bool CheckLicenseValidity()
    {
        return TimeCurrent() < license_expiry;
    }
};

## Performance Optimization

### 1. Code Optimization

#### Efficient Data Structures

```mql5
// Use appropriate data structures for performance
class COptimizedDataStructure
{
private:
    // Use dynamic arrays for variable-size data
    double price_buffer[];

    // Use fixed arrays for known-size data
    double indicator_values[100];

    // Use hash maps for fast lookups
    CHashMap<string, double> symbol_data;

public:
    void OptimizeArrayAccess()
    {
        // Reserve array size to avoid frequent reallocations
        ArrayResize(price_buffer, 1000);
        ArraySetAsSeries(price_buffer, true);

        // Use ArrayCopy for bulk operations
        ArrayCopy(price_buffer, source_array, 0, 0, WHOLE_ARRAY);
    }
};
```

#### Algorithm Optimization

```mql5
// Optimize calculation algorithms
class CAlgorithmOptimization
{
public:
    // Use incremental calculations instead of full recalculation
    double CalculateIncrementalMA(double new_price, double old_ma, int period)
    {
        return old_ma + (new_price - old_ma) / period;
    }

    // Cache expensive calculations
    double GetCachedATR(string symbol, ENUM_TIMEFRAMES timeframe, int period)
    {
        static double cached_atr = 0;
        static datetime last_update = 0;

        if(TimeCurrent() - last_update > PeriodSeconds(timeframe))
        {
            cached_atr = iATR(symbol, timeframe, period);
            last_update = TimeCurrent();
        }

        return cached_atr;
    }
};
```

### 2. Resource Management

#### Memory Optimization

```mql5
// Implement efficient memory management
class CMemoryManager
{
public:
    void OptimizeMemoryUsage()
    {
        // Release unused arrays
        ArrayFree(unused_array);

        // Use object pooling for frequently created objects
        CObjectPool<COrderBlock> order_block_pool;

        // Implement lazy loading for large datasets
        LoadDataOnDemand();

        // Use weak references to avoid circular dependencies
        CWeakReference<CRiskManager> risk_manager_ref;
    }

    void MonitorMemoryUsage()
    {
        long memory_used = TerminalInfoInteger(TERMINAL_MEMORY_USED);
        long memory_free = TerminalInfoInteger(TERMINAL_MEMORY_AVAILABLE);

        double memory_usage_percent = (double)memory_used / (memory_used + memory_free) * 100;

        if(memory_usage_percent > 80)
        {
            TriggerMemoryCleanup();
        }
    }
};
```

### 3. Network Optimization

#### API Call Optimization

```mql5
// Optimize external API calls
class CNetworkOptimization
{
private:
    datetime last_api_call;
    int api_call_count;

public:
    bool CanMakeAPICall()
    {
        // Implement rate limiting
        datetime current_time = TimeCurrent();

        if(current_time - last_api_call < 60) // 1 minute
        {
            if(api_call_count >= 10) // Max 10 calls per minute
            {
                return false;
            }
        }
        else
        {
            api_call_count = 0;
        }

        return true;
    }

    void OptimizeAPIUsage()
    {
        // Batch API requests
        BatchAPIRequests();

        // Use caching to reduce API calls
        UseCachedData();

        // Implement retry logic with exponential backoff
        RetryWithBackoff();
    }
};
```

## Backup and Recovery

### 1. Backup Strategy

#### Automated Backup System

```mql5
class CBackupManager
{
private:
    string backup_directory;
    int max_backups;

public:
    bool Initialize(string backup_dir, int max_backup_count = 30)
    {
        backup_directory = backup_dir;
        max_backups = max_backup_count;

        // Create backup directory if it doesn't exist
        if(!FolderCreate(backup_directory))
        {
            Print("Failed to create backup directory: ", backup_directory);
            return false;
        }

        return true;
    }

    void CreateDailyBackup()
    {
        string timestamp = TimeToString(TimeCurrent(), TIME_DATE);
        string backup_folder = backup_directory + "/" + timestamp;

        // Create daily backup folder
        FolderCreate(backup_folder);

        // Backup configuration files
        BackupConfigFiles(backup_folder);

        // Backup log files
        BackupLogFiles(backup_folder);

        // Backup performance data
        BackupPerformanceData(backup_folder);

        // Cleanup old backups
        CleanupOldBackups();
    }

    void BackupConfigFiles(string backup_folder)
    {
        // Copy EA configuration files
        FileCopy("SniperEA_Config.ini", backup_folder + "/SniperEA_Config.ini");
        FileCopy("RiskProfile.set", backup_folder + "/RiskProfile.set");
        FileCopy("SessionConfig.ini", backup_folder + "/SessionConfig.ini");
    }

    void CleanupOldBackups()
    {
        // Keep only the last N backups
        // Implementation depends on file system operations
    }
};
```

#### Configuration Backup

```mql5
// Backup EA configuration
void BackupConfiguration()
{
    string config_backup = "SniperEA_Config_" + TimeToString(TimeCurrent(), TIME_DATE) + ".bak";

    int file_handle = FileOpen(config_backup, FILE_WRITE | FILE_TXT);
    if(file_handle != INVALID_HANDLE)
    {
        // Write current configuration
        FileWrite(file_handle, "RiskPercent=" + DoubleToString(RiskPercent));
        FileWrite(file_handle, "MaxRiskPercent=" + DoubleToString(MaxRiskPercent));
        FileWrite(file_handle, "OrderBlock_MinSize=" + IntegerToString(OrderBlock_MinSize));
        // ... write all parameters

        FileClose(file_handle);
        Print("Configuration backed up to: ", config_backup);
    }
}
```

### 2. Recovery Procedures

#### Disaster Recovery Plan

```mql5
class CDisasterRecovery
{
public:
    bool ExecuteRecoveryPlan()
    {
        Print("Executing disaster recovery plan...");

        // Step 1: Stop all trading activities
        StopAllTrading();

        // Step 2: Close all open positions (if required)
        if(ShouldCloseAllPositions())
        {
            CloseAllPositions();
        }

        // Step 3: Backup current state
        BackupCurrentState();

        // Step 4: Restore from last known good configuration
        RestoreConfiguration();

        // Step 5: Validate system integrity
        if(!ValidateSystemIntegrity())
        {
            Print("System integrity validation failed");
            return false;
        }

        // Step 6: Restart EA with safe parameters
        RestartWithSafeParameters();

        Print("Disaster recovery completed successfully");
        return true;
    }

    void RestoreConfiguration()
    {
        // Find latest backup
        string latest_backup = FindLatestBackup();

        if(latest_backup != "")
        {
            // Restore configuration from backup
            LoadConfigurationFromBackup(latest_backup);
            Print("Configuration restored from: ", latest_backup);
        }
        else
        {
            // Use default safe configuration
            LoadDefaultSafeConfiguration();
            Print("Using default safe configuration");
        }
    }

    void LoadDefaultSafeConfiguration()
    {
        // Set ultra-conservative parameters
        RiskPercent = 0.1;
        MaxRiskPercent = 1.0;
        DailyLossLimit = 0.5;
        OrderBlock_MinSize = 50;
        BOS_MinBreakSize = 30;
        TradeAsiaSession = false;
        AvoidNewsMinutes = 120;
    }
};
```

#### System Recovery Validation

```mql5
bool ValidateSystemRecovery()
{
    bool recovery_successful = true;

    // Check EA compilation
    if(!IsEACompiled())
    {
        Print("ERROR: EA not properly compiled");
        recovery_successful = false;
    }

    // Check configuration integrity
    if(!ValidateConfiguration())
    {
        Print("ERROR: Configuration validation failed");
        recovery_successful = false;
    }

    // Check account connectivity
    if(!TerminalInfoInteger(TERMINAL_CONNECTED))
    {
        Print("ERROR: Terminal not connected");
        recovery_successful = false;
    }

    // Check trading permissions
    if(!AccountInfoInteger(ACCOUNT_TRADE_ALLOWED))
    {
        Print("ERROR: Trading not allowed");
        recovery_successful = false;
    }

    // Test basic functionality
    if(!TestBasicFunctionality())
    {
        Print("ERROR: Basic functionality test failed");
        recovery_successful = false;
    }

    return recovery_successful;
}
```
