The "Market Index at a Glance" app provides information so that you can view the stock index at a glance.
You can check the domestic stock market, the US stock market, the exchange rate, and international oil prices at once.
I hope this helps to make a quick judgment in the same stock market.

1. Domestic stock market: KOSPI, KOSDAQ, KOSPI 200
