TRADERS WORKSHOP Achieving and maintaining an ultra-low latency FX trading infrastructure “Achieving ultra-low latency requires a holistic approach that meticulously optimises each step from data transmission to execution” Alexander Culiniac Ultra-low latency trading can be defined as a system capable of processing data in nanoseconds, compared to standard low latency which is measured in milliseconds or microseconds. Bridging this gap is expensive, though, and requires specialised hardware and software. “It is not just about going faster; it’s about designing a sleek, custom built engine capable of conquering those tiny fractions of time that make all the difference in high stakes trading,” explains Ariel Silahian, Director of Electronic Trading at SiS Software Factory. You can pay to be as close to the exchange as possible, but with equitable access you can only get as close as other participants states Gordon McArthur, CEO of Beeks Group. “If you have fixed latency budgets then your competitors generally do as well, so ultra-low latency is about ensuring all other elements of your trading system are as fast as possible,” he says. The number of participants in the market at different stages of implementing ultra-low latency limits the benefits since interactions between two parties will only be as fast as the slowest participant observes Alexander Culiniac, CTO/ Managing Director of the commercial banking & payment product business group at SmartTrade Technologies. ATTENTION TO DETAIL IS VITAL “An FX trading platform must contend with various latency types, such as network, propagation, processing, and software-related delays,” says Culiniac. “Achieving ultra-low latency requires a holistic approach that meticulously optimises each step from data transmission to execution.” The primary users of these systems include high-frequency trading firms, hedge funds, and market makers, although as the value of improved performance rises relative to infrastructure costs, firms across the sell-side and buy-side are looking to achieve ultra-low latency. Silahian notes that the decentralised, fragmented nature of the FX market presents some specific challenges. “Unlike equities, FX is more about exploiting delayed prices across different platforms,” he says. “Execution speed is generally a little slower - even the fastest margin FX broker isn't as quick on the draw as Nasdaq. In addition, looser regulation in FX leads to protective measures by market players against high speed trading strategies, such as speed bumps or last look.” “The primary protocol for FX market data and trading is slow, lacks traceable timing, and is peer-to-peer rather than multicast observes McArthur. “Some FX markets have started to offer lower latency multicast market and binary trading protocols, but these are still in the minority,” he says. “With no single source, it takes a lot more time and effort to apply the methodical approach to ensuring latency-tuned access between participants.” Specific factors that impact latency include: • Slow infrastructure (servers/network cards/switches) • Additional infrastructure adding hops (firewalls, layers of switches) The decentralised, fragmented nature of the FX market presents some specific challenges • Physical distance from trading counterparties 70 NOVEMBER 20<strong>23</strong> e-FOREX
