FI Investments' High-Speed Trading Software: A Modern Approach
FI Investments, a leading company in the financial industry, has built a cloud-native, modular trading software that leverages modern cloud computing technologies for scalable, flexible, and efficient processing. This modern approach contrasts with traditional banking systems that often rely on legacy infrastructure.
The trading system at FI Investments consists of multiple layers, each with specific technologies and unique features. It is designed to handle real-time data processing, decentralized architectures, and enhanced automation via APIs and AI-driven components. This enables rapid order execution, better risk management, and seamless integration across platforms.
The software combines classical time series statistics, fuzzy regulators, and a proprietary neural network. It does not use popular machine learning frameworks or external math libraries, demonstrating a focus on custom solutions tailored to the demands of fast-paced trading environments.
Containers are used in the system, not just for their inherent statelessness, but also for stateful sets with persistent volume claims in many productive scenarios, especially in regulated proprietary trading. This ensures traceability and revocability, meeting regulatory requirements from BaFin's perspective for a persistent container architecture.
Immutable container images are deployed following a continuous CI/CD pipeline, ensuring the system's reliability and security. The control handover must be decided in the code for microsecond advantages, demonstrating the system's ability to make quick decisions.
Manual overrides in real-time can sacrifice performance and open attack and error potential. To address this, the parameters are not guessed via genetic algorithms but recalibrated weekly in an offline grid of 40 GPU nodes. Micro-batches are pushed directly into shared memory to achieve response times in the microsecond range.
For full traceability of all trading decisions, a "Flying Recorder" is used to store every incoming price tick, model response, and executed order with nanosecond precision. This allows regulatory relevant trades to be reconstructed and allocated ex-post. The system's proprietary protocol with challenge handshake provides network-side protection, with anomalous packet sequences triggering an immediate quarantine swing to the reserve node.
FI Investments' approach prioritizes in-memory architectures over committee workflows, emphasizing the importance of speed and automation in high-speed trading. The company follows DevSecOps and Governance within BaFin limits, ensuring compliance while maintaining the system's high-speed capabilities.
In practical implementation, standard protocols alone are not sufficient for latency-sensitive scenarios. The platform demonstrates that a regulatory-compliant setup can coexist with microsecond decisions and seamless audits, setting a new standard in the fintech industry.
The newsletter could highlight that FI Investments' high-speed trading software, with its data-and-cloud-computing technology, is tailored to the demands of fast-paced trading environments, incorporating proprietary solutions such as fuzzy regulators and AI-driven components.
The system's unique features include the use of containers for both stateless and stateful sets, ensuring traceability and revocability, and adhering to regulatory requirements. The software, which follows DevSecOps and Governance, also showcases the coexistence of a regulatory-compliant setup with microsecond decisions and seamless audits, elevating fintech industry standards.
