MQL5-Python Translation Workspace Skill

Seamless MQL5 indicator translation to Python with autonomous validation and self-correction.

When to Use This Skill

Use this skill when the user wants to:

• Export market data or indicator values from MetaTrader 5
• Translate MQL5 indicators to Python implementations
• Validate Python indicator accuracy against MQL5 reference
• Understand MQL5-Python workflow capabilities and limitations
• Troubleshoot common translation issues

Activation Phrases: "MQL5", "MetaTrader", "indicator translation", "Python validation", "export data", "mql5-crossover workspace"

Core Mission

Main Theme: Make MQL5-Python translation as seamless as possible through:

1. Autonomous workflows (headless export, CLI compilation, automated validation)
2. Validation-driven iteration (>=0.999 correlation gates all work)
3. Self-correction (documented failures prevent future mistakes)
4. Clear boundaries (what works vs what doesn't, with alternatives)

Workspace Capabilities Matrix

WHAT THIS WORKSPACE CAN DO

1. Automated Headless Market Data Export (v3.0.0)

Status: PRODUCTION (0.999920 correlation validated)

What It Does:

• Fetches OHLCV data + built-in indicators (RSI, SMA) from any symbol/timeframe
• True headless via Wine Python + MetaTrader5 API
• No GUI initialization required (cold start supported)
• Execution time: 6-8 seconds for 5000 bars

Command Example:

CX_BOTTLE="MetaTrader 5" \
WINEPREFIX="$HOME/Library/Application Support/CrossOver/Bottles/MetaTrader 5" \
wine "C:\\Program Files\\Python312\\python.exe" \
  "C:\\users\\crossover\\export_aligned.py" \
  --symbol EURUSD --period M1 --bars 5000

Use When: User needs automated market data exports without GUI interaction

Limitations: Cannot access custom indicator buffers (API restriction)
