LS Securities said on the 9th it will hold a transaction fee discount event for customers who use its open API.
The event was prepared to match the expansion of calls per second on the open API. Generally, when retrieving information such as orders, quotes, and bid-ask data through an open API, the number of possible calls per second is limited to prevent server overload from excessive requests. LS Securities recently expanded the number of calls per second on the open API to about three times the previous level, building an environment where investors can receive more information and process orders quickly.
LS Securities will cut transaction fees for exchange-traded funds (ETF) and exchange-traded notes (ETN) via the open API from 0.015% to 0.005%, and domestic stock futures transaction fees from 0.004% to 0.002%, respectively. The event fees apply only to transactions through the open API, and transactions via MTS, HTS, and xing API are excluded from the discount.
The event runs through Feb. 27, 2026. The discounted fees apply from the date of application through the end of the event period.
During the event period, LS Securities will also offer an additional benefit of one year of OPEN API negotiated fees to customers whose ETF or ETN transaction amount reaches 10 billion won or more, or whose stock futures transaction amount reaches 40 billion won or more.
An LS Securities official said, "Given the nature of products that require frequent trading, the expense savings for investors are expected to be significant," adding, "We will continue to strengthen our API competitiveness and work to build a platform that anyone can use easily."
