🎯 Purpose

Retrieve live market pricing for a specific symbol. Useful for:

• Displaying real-time bid/ask prices
• Building dashboards or widgets
• Monitoring spreads and triggering alerts

🧩 Notes & Tips

• Precision: Print with instrument-specific decimals (e.g., 5 for EURUSD). Keep raw values for calculations.
• Timestamp: DateTime is UTC — format for display, log in UTC.

---

⚠️ Pitfalls

• Zero/invalid values: Check Bid > 0 && Ask >= Bid. Otherwise treat as stale.
• Wrong symbol string: Use the exact broker symbol (including suffixes).

---

🧪 Testing Suggestions

• Happy path: EURUSD → Ask > Bid, timestamp recent.
• Error path: Unknown/disabled symbol → return error or empty data handled gracefully.
