Introduction

C is a foundational programming language recognized for its efficiency, hardware control, and portability.
It is widely used in system-level programming, embedded systems, and high-performance applications.

Readability

C features a minimalistic and concise syntax, which can be advantageous and challenging.
Beginners may struggle with C's readability due to complex concepts like pointer arithmetic and manual memory management.
The use of macros and preprocessor directives can obscure code logic, complicating understanding for developers.

Writability

C is highly writable where low-level operations and direct memory access are needed.
It offers a limited set of keywords and constructs, enabling compact and efficient code.
The absence of higher-level abstractions results in more lines of code required to achieve the same functionality as higher-level languages.
Manual memory management raises the risk of errors, making development potentially less productive.

Reliability

Reliability hinges on the programmer's skill, given C's minimal runtime error checking and lack of automatic memory management.
Developers face risks of memory leaks, buffer overflows, and undefined behavior without careful management.
Experienced developers can leverage C's simplicity and predictability to write reliable code, especially in embedded systems.
The lack of built-in exception handling and dynamic type checking necessitates thorough testing and disciplined coding practices to ensure reliability.

Cost

C is open-source and widely supported, maintaining low direct costs for developers.
The language has an extensive history, enabling the availability of numerous resources, libraries, and tools to reduce development costs.
A steep learning curve and potential for difficult bugs can increase long-term development and maintenance costs.
C's efficiency makes it a cost-effective option for performance-critical applications, despite higher debugging and testing costs.

Conclusion

C is a powerful language for systems programming and scenarios requiring low-level hardware access.
Its simplicity, portability, and efficiency make it favorable but require careful consideration due to trade-offs in readability, writability, and reliability.
The costs associated with C development are mitigated by its control over system resources and its prevalence in performance-critical applications.

High-Frequency Trading Systems

High-frequency trading (HFT) involves executing numerous trades at very high speeds, often within microseconds.
System requirements include low latency, high throughput, precise timing, memory efficiency, and robust error handling.

Python for HFT

Python is recognized for simplicity, readability, and a rich ecosystem of libraries for financial tasks.
Performance limitations include:
- Python is an interpreted language, slower than compiled alternatives like C++.
- The Global Interpreter Lock (GIL) restricts multi-threading, hindering low-latency execution.
Memory management issues arise from dynamic typing and garbage collection, potentially introducing delays.
Lack of control over system resources due to abstraction limits optimization for performance.
Python may serve auxiliary roles, such as strategy development, but is impractical for real-time execution in HFT.

C++ for HFT

C++ is a high-performance compiled language, favored for HFT systems.
Key advantages include:
- Ultra-low latency due to machine-level optimization of code.
- Precise memory management facilitating manual allocation/deallocation, thus minimizing latency.
- Strong support for multi-threading and parallelism, absent Python's GIL, enabling simultaneous operations without overhead.
- Optimized resource control allowing targeted management of CPU usage, memory, and system efficiency.
C++ meets the critical performance and precision needs of HFT systems, making it suitable for core components.

Conclusion

Python, while excellent for ease of use and rapid development, lacks the performance needed for HFT core functions.
C++ is essential for creating low-latency, high-performance trading systems, capable of meeting stringent HFT demands.
Building a real-time, resource-controlled HFT system solely in Python is impractical, whereas C++ makes it feasible.
