บทความนี้เป็นDeep Diveสำหรับวิศวกรที่ต้องการเก็บข้อมูล OrderBook ของ Deribit Options ผ่าน Tardis API โดยใช้ HolySheep AI สำหรับ Real-time Analysis ด้วย Latency ต่ำกว่า 50ms และประหยัดต้นทุน 85%+ เมื่อเทียบกับการใช้ OpenAI โดยตรง พร้อมโค้ด Production-Grade ที่รันได้จริง วัดผลได้ และ Scale ได้

Deribit Option OrderBook: ทำไมต้องเก็บข้อมูลผ่าน Tardis

Deribit เป็นSpot Exchange ที่ใหญ่ที่สุดสำหรับ Bitcoin Optionsด้วย Open Interest มากกว่า $10B ทุกวัน OrderBook ของ Deribit มีโครงสร้างที่ซับซ้อนกว่า Spot เนื่องจาก Options มี:

Tardis API เป็นAggregated Feedที่รวม Market Data จาก Exchange หลายตัว รวมถึง Deribit ทำให้ได้ข้อมูลที่:
