主動式 ETF 雷達

【Active ETF Radar】is an active ETF trading analysis tool designed specifically for Taiwanese retail investors. It lets you see stocks from an institutional investor's perspective—real-time tracking of active ETF buying and selling activity, identifying synchronized buy/sell signals, new additions and removals, and consensus rankings.

━━━ Core Functions ━━━
Daily Signal Summary
Automatically pushes the top active ETF synchronized buying/selling signals at 19:30 daily, ensuring you don't miss any institutional investor movements.

Cross-ETF Consensus Ranking
Clearly see how many active ETFs are simultaneously buying or selling the same stock; higher consensus indicates a more consistent institutional investor perspective.

Foreign Investor Synchronized Signals (Double Consensus)
In addition to ETF buying, it also overlays foreign net buying and daily institutional investor trading volume, filtering out noise such as "cumulative slight positive but recent net selling."

📈 Top N Holdings Ranking: Ranking across all actively managed ETFs, sorted by both number of shares and trading value, providing a differentiated interpretation of market trends.
