So, what exactly are High-Frequency Trading (HFT) firms, and why have they become critical to today’s financial ecosystem? More commonly referred to today as proprietary trading or quantitative trading firms, these entities specialise in executing algorithmic strategies powered by advanced mathematics and cutting-edge technology. They operate at ultra-high speeds, submitting thousands of orders per second, with the aim of exploiting price movements within extremely short timeframes, often ranging from microseconds to a few seconds. The goal is to capture “alpha” and close out most, if not all, positions before the end of the trading day. Typical strategies include statistical arbitrage, index arbitrage, dual-listed arbitrage, and market making (simultaneous bid and offer placements to profit from the spread). HFT firms are a significant revenue driver for exchanges, generating income through execution, clearing, settlement, collocation, and market data services. Sell-side firms also benefit, gaining a steady revenue stream and increasing market share. Infrastructure Evolution: JSE’s Leap Forward A significant turning point came in 2012 when the Johannesburg Stock Exchange (JSE) migrated to the Millennium IT platform (owned by the London Stock Exchange Group). The JSE introduced its colocation facility two years later, offering traders ultra-low-latency access. The Millennium platform supports both Native and FIX protocols for order entry, post-trade processing, and drop copies, along with market data feeds via the MITCH (Millennium ITCH) and FIX/FAST protocols. Many firms prefer native binary protocols for their speed and unthrottled MITCH feeds to capture every possible microsecond advantage in market data processing. For firms trading in South Africa, opting for the unthrottled feed over the throttled version is essential. The JSE has continuously enhanced their platform to meet the needs of both institutional investors and HFT players. A key upgrade came in 2024 with the implementation of self-match prevention, designed to prevent internal teams from inadvertently trading against themselves, a costly mistake both in fees and regulatory scrutiny. On the other side of the spectrum, tools like pegged hidden orders, central order book crossing for client/prop flows, and spread-sensitive execution features have been rolled out to support institutional and sell-side players in navigating fast-paced, HFT-dominated markets. Colocation 2.0: World-Class Access at Lower Costs Though compact, the JSE’s colocation facility is a Tier 3 data centre meeting global standards. It's equipped with a robust battery and generator backup, critical in a country where power outages remain challenging. The 2023 launch of Colocation 2.0, in partnership with Beeks and IPC, introduced cloud-based access options. This provides a lower-barrier entry point for firms exploring Africa’s most sophisticated exchange. Starting at under $200 per month (excluding data costs), firms can connect to the JSE’s test environment, market data, and reference data feeds within the collocated ecosystem. These infrastructure upgrades laid the groundwork for international quant and HFT firms to target South Africa, with a noticeable uptick in trading volume and order flow to show for it. Rise of Retail Retail equity trading in South Africa has seen a notable uptick in recent years, driven by greater accessibility to online trading platforms, the rise of fintech, and an increasingly financially literate population. Low-cost brokers and app-based trading platforms have significantly democratised access to the JSE, enabling everyday South Africans to invest in local stocks with minimal capital. This shift has been particularly pronounced among younger investors, who are more digitally savvy and inclined toward self-directed investment strategies. While retail volumes still lag institutional and high-frequency players, their growing participation reshapes market dynamics, prompting brokers to enhance user experience, lower fees, and offer more educational content and analytical tools tailored to this emerging investor class. Much more can be done in this space to provide retail with live pricing This has also been a contributing factor as HFT firms want to trade with retail participants who trade through the spread. RA2X and Market Competition: Fueling Sophistication The local trading landscape has also become more competitive, due to alternative venues like A2X. Offering advanced technology and competitive fees, A2X has carved out a decent market share by attracting both local and global trading firms. With no admission to a trade model, however, or a stance on an MTF framework, it has been a difficult journey for A2X to onboard new issuers, but it has done exceptionally well in terms of onboarding 180+ listings with a market capitalisation of R9 trillion. This is a boon for HFT firms, who benefit from increased liquidity and more arbitrage opportunities across exchanges. The emergence of multiple trading venues has pushed sell-side firms to enhance their technological capabilities—implementing smart order routers, upgrading sell-side algorithms, robust settlement solutions and offering low-latency access to enable both institutional clients and HFTS to execute efficiently. This growing sophistication reflects the broader maturation of South Africa’s capital markets. A Market of Strategic Importance South Africa’s highly liquid markets, unique blend of advanced market infrastructure, regulatory frameworks, competitive dynamics, and its role as a financial gateway to Africa make it a compelling destination for high-frequency and quantitative trading firms. As these firms deepen their presence, they’re contributing to the ongoing evolution of the market and the continent, driving innovation, improving efficiency, and expanding participation. Absa has positioned itself as a key enabler in this transformation. It offers HFT firms ultra-low-latency access, deep market infrastructure expertise, a robust stock loan pool, and a strong balance sheet to support advanced trading strategies. As the rest of Africa opens to these possibilities, Absa remains ready to unlock these opportunities for our clients by already having a presence in several African countries. https://cib.absa.africa/wp-content/uploads/2020/07/file_example_MP3_700KB.mp3 Related Articles FINTECH Africa’s Tech Sector is Powering Up in 2025 Even in the harshest environments, growth can flourish in unexpected ways.
