Why the Broker Queue Matters · 為什麼經紀掛單如此重要

Research Note · 研究筆記

In the Hong Kong stock market, the order book is uniquely transparent. Unlike many global markets where dark pools hide institutional flow, HKEX publishes the top 10 bid and ask queues by broker ID in real time. Our Broker Queue (經紀掛單) factor leverages this transparency to track "smart money" positioning.

在港股市場，訂單簿具有獨特的透明度。與許多隱藏機構流量的全球市場不同，港交所即時公佈前十大買賣經紀代號。我們的經紀掛單因子正是利用這種透明度來追蹤「聰明錢」的佈局。

Institutional vs. Retail Brokers · 機構與散戶經紀

Market participants generally categorize brokers into two groups:

• Institutional Brokers (e.g., 1274, 1275, 1220): These IDs typically represent large investment banks, sovereign wealth funds, and northbound/southbound capital flows. Their positioning reflects long-term conviction or macro hedging.
• Retail Brokers (e.g., 0001, 0002, 0003): These IDs represent local retail brokerages. When retail queues are heavily bid while institutional queues are offering, it often signals a local top or "dumb money" trap.

市場參與者通常將經紀分為兩類：機構經紀（代表大型投行、主權基金、南北水）反映長線信念或宏觀對沖；散戶經紀（代表本地證券商）。當散戶大舉掛單買入而機構出貨時，往往預示短線見頂。

How We Score It · 我們如何評分

Our algorithm scans the top 10 bid and ask queues for every HSI constituent. If institutional brokers dominate the bid side (net accumulation) while retail brokers dominate the ask side (distribution), the stock receives a high Broker Queue score (8-10). This often precedes price breakouts by 1 to 3 sessions.

我們的算法掃描每隻恒指成份股的前十大買賣掛單。若機構經紀主導買盤（淨吸納），而散戶經紀主導賣盤（出貨），該股將獲得高經紀掛單評分（8-10）。這往往領先價格突破 1 至 3 個交易日。
