WebSocket API v1 - মার্কেট ডেটা ফিডের উদাহরণ

একবার WebSocket API v1-এর সাথে একটি সংযোগ স্থাপন করা হলে (সর্বজনীন URL wss://ws.kraken.com/ ব্যবহার করে), নিম্নলিখিত একটি সাবস্ক্রিপশন বার্তা পাঠিয়ে মার্কেট ডেটা ফিডগুলিতে সাবস্ক্রাইব করা যেতে পারে:

নিম্নলিখিতটি টিকর ফিডের একটি উদাহরণ, যা বিভিন্ন মার্কেট ডেটা পরিবর্তনের জন্য প্রাপ্ত বার্তাগুলির ধরন চিত্রিত করে (যেমন ট্রেড সংঘটিত হওয়ার কারণে সেরা বিড/আস্ক ভলিউম পরিবর্তন):

উল্লেখ্য যে, যখন কোনো টিকর (বা অন্যান্য মার্কেট ডেটা) উপলব্ধ থাকে না, তখন প্রতি সেকেন্ডে 1টি হার্টবিট বার্তা পাঠানো হয়।

টিকর ফিডের জন্য JSON বার্তাগুলির মধ্যে থাকা স্বতন্ত্র ক্ষেত্র/মানগুলির বিবরণ (এবং অন্যান্য সমস্ত মার্কেট ডেটা ফিড) আমাদের WebSocket API v1 ডকুমেন্টেশনে উপলব্ধ।
