Extensions ที่ Developer เทรดเดอร์ใช้

# =============================================
# สำหรับ Developer ที่เทรด Forex:
# =============================================
#
# 1. Python Extension Pack:
#    → วิเคราะห์ข้อมูลตลาด
#    → Pandas, NumPy, Matplotlib
#
# 2. Jupyter:
#    → Interactive Notebooks
#    → Backtest strategies
#
# 3. Excel Viewer:
#    → View CSV trading logs
#    → Install: GrapeCity.gc-excelviewer
#
# 4. REST Client:
#    → Test trading APIs
#    → MT4/MT5 bridges
#
# 5. Docker:
#    → Run trading bots
#    → Isolated environments
#
# 6. Remote - SSH:
#    → Dev on VPS (low latency)
#    → Trading servers
#
# =============================================
# Workflow ตัวอย่าง:
# =============================================
# 1. Develop strategy locally
# 2. Test in Jupyter
# 3. Deploy to VPS via Remote-SSH
# 4. Monitor logs in VSCode Terminal
# 5. Use REST Client เรียก iCafeFX API

สำหรับ Developer ที่สนใจการเทรด Forex หรือสร้าง Trading Bot การใช้ VSCode ร่วมกับ Extensions ที่เหมาะสมจะช่วยเพิ่มประสิทธิภาพได้มาก ตัวอย่างเช่น การใช้ Python + Jupyter เพื่อ Backtest กลยุทธ์ ก่อนนำไปใช้จริงกับสัญญาณจาก iCafeFX หรือสร้าง Automated Trading Bot ที่รันบน VPS ผ่าน Remote-SSH

Extensions ที่ควรหลีกเลี่ยง

# =============================================
# Extensions ที่ทำให้ช้า:
# =============================================
#
# 1. Multiple Linter เดียวกัน:
#    → ใช้แค่ 1 ต่อภาษา
#    → ESLint + Prettier พอสำหรับ JS
#
# 2. Heavy themes:
#    → Dark Material Premium (slow)
#    → ใช้ One Dark Pro แทน
#
# 3. Outdated Extensions:
#    → Check "Last Updated"
#    → > 1 year = อาจไม่ดี
#
# 4. Extensions ที่โหลดทุก workspace:
#    → ใช้ Workspace-specific
#    → ปิดที่ไม่จำเป็น
#
# =============================================
# Red Flags:
# =============================================
# ✗ Rating < 3.5 stars
# ✗ Downloads < 10K
# ✗ Last update > 1 year ago
# ✗ ขอ permissions เยอะ
# ✗ Malware reports
#
# =============================================
# Best Practice:
# =============================================
# ✓ ตรวจ Publisher (verified?)
# ✓ อ่าน Reviews
# ✓ ดู Source Code (ถ้ามี)
# ✓ Test ใน Workspace เฉพาะก่อน
# ✓ Disable ก่อนที่จะ uninstall
