Giới Thiệu Tổng Quan
Trong thị trường crypto derivatives, dữ liệu Open Interest (OI) và Long/Short Position Ratio là hai chỉ số then chốt giúp trader đánh giá cục diện thị trường. Bài viết này sẽ hướng dẫn bạn xây dựng hệ thống thu thập và phân tích dữ liệu từ Gate.io và KuCoin perpetual contracts thông qua HolySheep AI API — giải pháp tiết kiệm 85%+ chi phí so với các provider truyền thống.Từ kinh nghiệm thực chiến của tác giả khi xây dựng hệ thống position gaming factor cho quỹ hedge fund, việc sở hữu dữ liệu OI lịch sử chính xác và có độ trễ thấp là yếu tố quyết định thành bại của chiến lược.
