การสร้างระบบ Quantitative Trading ที่แม่นยำเริ่มต้นจากข้อมูลที่ถูกต้อง บทความนี้จะพาคุณสร้าง Data Pipeline สำหรับ Backtesting โดยใช้ HolySheep AI ร่วมกับ Tardis (บริการ Streaming ข้อมูลตลาดการเงิน) เพื่อประมวลผลข้อมูล OHLCV และ Market Depth แบบ Real-time ได้ในค่าใช้จ่ายที่ประหยัดกว่า 85% เมื่อเทียบกับการใช้ OpenAI โดยตรง

ทำไมต้องใช้ Data Pipeline สำหรับ Backtesting

ในระบบ Quantitative Trading การทดสอบย้อนกลับ (Backtesting) ต้องอาศัยข้อมูลปริมาณมหาศาล ไม่ว่าจะเป็น OHLCV (Open, High, Low, Close, Volume), Order Book, Trade Ticks หรือ Funding Rate ข้อมูลเหล่านี้ต้องถูกจัดเก็บ ทำความสะอาด และประมวลผลก่อนนำไปวิเคราะห์

ปัญหาหลักที่ Quant Trader ทุกคนเจอ:

สถาปัตยกรรมระบบ HolySheep + Tardis Pipeline

ระบบประกอบด้วย 3 ส่วนหลัก:

  1. Tardis Streaming Layer — รับข้อมูล Real-time จาก Exchange
  2. Data Processing Layer — ใช้ HolySheep API สำหรับ Feature Engineering
  3. Storage Layer — จัดเก็บข้อมูลสำหรับ Backtest
