Summary
In this chapter, we illustrated how to use Python in HFT. Python is not a language for performance and low latency, and we highlighted how to use other languages such as C++ to get to the same performance level. You are now capable of using any HFT-specific C/C++ code in your Python code.
We will now finish this book by opening up to some new topics in the next chapter, such as achieving less than 500 nanoseconds for tick-to-trade latency with Field Programmable Gate Array (FPGA), and opening HFT systems to cryptocurrencies.
