Solving the problem of "order congestion" during the booming stock market

The sharp increase in trading volume places great demands on securities companies as they must both serve large trading volumes and satisfy investor experience.

From the period when liquidity of 40,000 billion was a record, the stock market is now continuously recording the most exciting trading sessions. Notably, on July 29, 2025 and August 5, 2025, the cash flow matched on the HoSE floor exceeded 70,000 billion VND, marking impressive growth.  

The sharp increase in trading volume has placed greater demands on technology infrastructure, as evident in the fact that some securities companies have “frozen” during record trading sessions. The positive point is that the HoSE trading system is still running smoothly and conveniently, without the “order congestion” that occurred in the 2020-2021 period. This is considered a remarkable achievement after the new KRX technology system was officially put into operation in early May 2025.

At the seminar "Ensuring technological infrastructure during the stock market boom", part of the program series "Innovation - Leverage for the new era" organized by the Finance - Investment Newspaper, Mr. Ngo Quang Huy, Deputy General Director of Financial Software Solutions Company (FSS) assessed that the recent record-breaking trading sessions can be considered a test of the "endurance" of the system.  

FSS is currently the core solution provider for more than 35 securities companies and 10 fund management companies. The recent explosive trading sessions are within the response capacity that FSS and the securities companies have researched and prepared.  

“FSS, together with securities companies, has made strategic investments over a long period of time to build a technology infrastructure, including software solutions and hardware infrastructure, which not only meets today's trading requirements but can also meet the current 3-5 times increase,” said Mr. Huy.  

Assessing the KRX project as a historical milestone of the Vietnamese stock market, Mr. Ngo Quang Huy said that the new system has strong processing capacity, like a larger and wider highway. But more than that, for securities companies and technology infrastructure solution providers such as FSS, the system not only increases processing capacity, completely solves the problem of order congestion, but also serves as a foundation for deploying many new products, such as intraday trading, options, short selling, etc.

In the context of more active investor participation and stronger capital flows into the market, especially when Vietnam's securities market is upgraded, the development of technology systems at this stage poses a challenge for securities companies and solution providers. That is the requirement to both serve the increasing trading volume and satisfy the user experience, from placing orders to monitoring risk management.  

The FSS Deputy General Director suggested that market members should prioritize system safety when investing in technology infrastructure, gradually switch to open architecture systems (such as API systems), increase external connections, develop new products, and invest in data to bring the best personalized experience to investors.  

“The stock market in the next 5-10 years will be a smart market, all investment decisions, risk management, and analysis will be based on artificial intelligence technology and Big Data, investors can trade seamlessly on the same multi-asset platform, including stocks, bonds, fund certificates, and later even cryptocurrencies,” Mr. Ngo Quang Huy predicted.  

From the perspective of a securities company, Ms. Vu Yen Dung, Director of Securities Operations Department, VPS Securities Company, said that VPS has also researched and applied a number of new technologies, both in the company's operations and in the customer experience.  

Ms. Dung said that at the time of the recent stock market “boom”, VPS’s system sometimes recorded 500,000-700,000 customers and the number of orders reached 700,000-800,000 orders/session, a record high in recent years. However, the VPS system still fully served the needs of customers smoothly.  

VPS representative said that in recent years, the company has regularly responded to the expansion of infrastructure technology and enhanced the experience of providing diverse investment services to investors in the market. From there, providing technological solutions to best support market fluctuations as well as the increase and expansion of scale in the past as well as in the future.  

“We apply AI to synthesize and analyze market information, improve the professional qualifications of the team, to provide information and help customers manage their investment portfolios effectively. We also apply Big Data to analyze customer experience and VPS's strategic operations,” Ms. Dung shared.

With a proactively developed platform system that can flexibly respond, VPS representatives are confident that in the coming time, especially with the prospect of market upgrades and explosive market growth, VPS will still be able to meet the needs.   The transaction volume can be increased many times in the future.
