สวัสดีครับนักพัฒนาและนักเทรดทุกคน วันนี้ผมจะมาแชร์ประสบการณ์การนำ Tardis.dev มาใช้ในโปรเจกต์ Quantitative Trading ด้วยภาษา Rust กันแบบละเอียดยิบเลยครับ
Tardis.dev คืออะไร และทำไมต้องเลือกใช้
Tardis.dev เป็นแพลตฟอร์มที่รวบรวม Historical Market Data สำหรับตลาดคริปโตเคอร์เรนซีโดยเฉพาะ ต่างจากทางเลือกอื่น เช่น CCXT หรือ exchanges' own APIs ที่มักจะมีข้อจำกัดเรื่อง rate limits และความครบถ้วนของข้อมูล
จุดเด่นของ Tardis.dev
- ความครบถ้วนของข้อมูล — รองรับกว่า 50 exchanges และ 100,000+ trading pairs
- WebSocket Streaming — รองรับ real-time data feed แบบ low-latency
- Historical Replay — สามารถ replay ข้อมูลย้อนหลังได้ตาม timestamp ที่ต้องการ
- รองรับหลาย Data Types — OHLCV, Trades, Orderbook, Ticker, Liquidation
- SDK หลายภาษา — มี SDK สำหรับ Python, Node.js, Go, Rust และอื่นๆ
การติดตั้งและ Setup Rust Project
เริ่มต้นด้วยการสร้าง Rust project และเพิ่ม dependencies ที่จำเป็นกันครับ
cargo new tardis-quantitative
cd tardis-quantitative
เพิ่ม dependencies ใน Cargo.toml
[dependencies]
tardis = "0.7"
tokio = { version = "1", features = ["full"] }
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
chrono = { version = "0.4", features = ["serde"] }
reqwest = { version = "0.12", features = ["json"] }
การดึงข้อมูล OHLCV Historical Data
มาเริ่มด้วยการเขียนโค้ดสำหรับดึงข้อมูล OHLCV (Open, High, Low, Close, Volume) จาก Tardis.dev กันครับ
