Read MetaTrader 5 log files directly to access Print() output from indicators, scripts, and expert advisors without requiring manual Experts pane inspection.

Purpose

Implement "Option 3" dual logging pattern:

  • Print() - MT5 log files (human-readable via Experts pane)

  • CSV files - Structured data (programmatic analysis)

Claude Code CLI can autonomously read both outputs without user intervention.

When to Use

Use this skill when:

  • Validating MT5 indicator/script execution

  • Checking compilation or runtime errors

  • Analyzing Print() debug output

  • Verifying unit test results (Test_PatternDetector, Test_ArrowManager)

  • User mentions checking "Experts pane" manually

Log File Location

MT5 logs are stored at:

$MQL5_ROOT/Program Files/MetaTrader 5/MQL5/Logs/YYYYMMDD.log

File Format:

  • Encoding: UTF-16LE (Little Endian)

  • Structure: Tab-separated fields (timestamp, source, message)

  • Size: Grows throughout day (typically 10-100KB)

Instructions

1. Construct today's log path

/usr/bin/env bash << 'SKILL_SCRIPT_EOF'
# Determine current date
TODAY=$(date +"%Y%m%d")

# Build absolute path
LOG_FILE="$MQL5_ROOT/Program Files/MetaTrader 5/MQL5/Logs/${TODAY}.log"
SKILL_SCRIPT_EOF

2. Read the entire log file

Use Read tool:

  • File path: Absolute path from step 1

  • The file contains all Print() statements from MT5 indicators/scripts

  • UTF-16LE encoding is automatically handled by Read tool

3. Search for specific content (optional)

Use Grep to filter entries:

Pattern: indicator name, "error", "test.*passed", etc.
Path: Log file path from step 1
Output mode: "content" with -n (line numbers)
Context: -A 5 for 5 lines after matches

4. Analyze recent entries (optional)

Use Bash with tail for latest output:

tail -n 50 "$LOG_FILE"

Common Validation Patterns

Check unit test results

Search for test pass/fail indicators:

Pattern: test.*passed|test.*failed|Tests Passed|Tests Failed|ALL TESTS PASSED
Output mode: content
Context: -B 2 -A 2

Find compilation errors

Pattern: error|ERROR|warning|WARNING|failed to create
Output mode: content
Context: -A 3

Monitor specific indicator

Pattern: CCI Rising Test|PatternDetector|ArrowManager
Output mode: content
Context: -A 2

View initialization messages

Pattern: OnInit|initialization|Initialization complete|Phase \d+
Output mode: content

Examples

Example 1: Validate unit test completion

Input: User compiled Test_PatternDetector.mq5
Action:
  1. Read today's log file
  2. Grep for "Test.*PatternDetector|Tests Passed|Tests Failed"
  3. Report results (e.g., "17 tests passed, 0 failed")
Output: Test status without user checking Experts pane

Example 2: Check for runtime errors

Input: User reports indicator not working
Action:
  1. Read today's log file
  2. Grep for "ERROR|error|failed" with -A 3 context
  3. Analyze error messages
Output: Specific error details and line numbers

Example 3: Verify Phase 2 arrow creation

Input: User asks "did the test arrow get created?"
Action:
  1. Read today's log file
  2. Grep for "Phase 2|Test arrow created|Failed to create"
  3. Check for success/failure messages
Output: Arrow creation status with timestamp

Security Considerations

  • Log files may contain sensitive trading data (symbol names, account info)

  • Restricted to Read, Bash, Grep tools only (no network access via WebFetch)

  • Do not expose absolute paths unnecessarily in user-facing output

  • Filter sensitive information when reporting results

  • No file modification operations allowed

Integration with Dual Logging

This skill enables programmatic access to one half of the dual logging pattern:

  • MT5 Log Files (this skill) - Human-readable Print() output

  • CSV Files (CSVLogger.mqh) - Structured audit trails for validation

Both are accessible without user intervention:

  • MT5 logs: Read via this skill

  • CSV files: Read directly via Read tool or validate_export.py

Validation Checklist

When using this skill:

Log file exists for today's date File size > 0 (not empty) Contains expected indicator/script output Timestamps match execution time Error messages (if any) are actionable Test results (if applicable) show pass/fail counts
