Korean Market Data
Daily Korean foreign-flow ranks and sector indices
What it is
A no-signup collection of Korean market files drawn from the Korea Exchange open API and related official sources. One download ranks foreign-investor net buying and selling for KOSPI and KOSDAQ names, with aggregates over one, five, and twenty sessions, in JSON and CSV. A second pair of files tracks exchange sector indices against the broad market and is refreshed each trading day under an attribution license. Analysts who want English tables of Korea-only flow and sector moves can cite them in research, but the collection is not a multi-market price API.
