What is Three Institutional Investors (三大法人) Net Buy/Sell?
The three major institutional investors in Taiwan's stock market — foreign investors (外資), investment trusts (投信), and dealers (自營商) — move large amounts of capital daily. Tracking their net buy/sell (purchases minus sales) reveals where institutional money is flowing into or out of a stock. Sustained net buying by foreign investors often signals bullish conviction; persistent selling may indicate exits or position reduction. Blave provides daily and historical 三大法人 data with cumulative trend charts.
How much time do you spend wiring APIs, pulling data, and debugging — instead of thinking about strategy? Describe the signal, and BlaveClaw researches and backtests it.
