Example use cases

Historical dual-price research for a specific date
“What were SK Hynix's stock prices on both the Korean and US markets on January 15, 2025? I need the KRX close in KRW, the SKHY ADR close in USD, and the USD/KRW rate for that day.”
Portfolio valuation in USD for KRX holding
“I hold SK Hynix shares on KRX and need to value them in dollars — can you get me yesterday's 000660 close price in KRW and the USD/KRW exchange rate so I can calculate the USD equivalent?”
