Summary

In this chapter, we learned that trading system communication is key to trading. The trading system is in charge of collecting the required prices to make an informed decision. If this component is slow, it will make the trading decision slower. Gateways are technically more challenging than any of the other components because they need to deal with the communication. The communication implies that layers are handled perfectly on the computer level; that is, the computer architecture (network layer), operating system (system calls, the driver that talks to the network card, and so on), and the software itself. All of these layers must be optimized so that they have a fast trading system. Because of their level of technical complexity, it is unlikely that you will implement this communication if you have strategies for high-frequency trading. Instead, you will use a system...
