Korea's US Stock Daytime Trading

The daytime trading that Samsung Securities first introduced was made possible through a partnership with Blue Ocean Exchange, founded in 2019. In exchange for Samsung Securities being the first to introduce it, Korea was able to hold a one-year monopoly. At first, not many seemed particularly interested, but

As trading volume surged and commission income began to flow in, the monopoly ended and most securities firms started to participate.

Thanks to this, trading volume soared more than 30-fold, and the service also expanded into Japan's Tokyo Stock Exchange.

Also, from 2023, Robinhood has formed a partnership, allowing American and Korean retail investors to trade together.

ADP stocks can be seen to be highly correlated with European markets or the Hong Kong stock market. For about 1,000 stocks, Jane Street participates as LP to keep prices in line. One thing to note: an average of 3,500 stocks are traded per day, but since LPs only manage fewer than 1,000, 2,500 stocks are traded without an LP.

Korea is also working to create a similar exchange. An alternative exchange called Nextrade is set to launch in Korea soon, and the goal is to enable 24-hour Security Token trading using blockchain technology.
