Programming Languages — Basics and Choices
In the last three chapters, we went through the structure of financial institutions and the business units that handle the various aspects of the trading activity. The business processes and practices that we explored in these chapters will resurface during the design phase of a trading platform project or, somewhat more painfully, during its implementation phase. These processes and practices form the basis of the user requirements of the trading platform. In order to meet these requirements, we need a sound understanding of the business. Though necessary, business knowledge is by no means sufficient because a trading platform is, first and foremost, a software design challenge. We therefore need to have a firm footing on computer science, software engineering and programming as well if we are to succeed in rolling out a robust trading platform.
Those of us who come with a more quantitative and mathematical, rather than technical and engineering, background may lack the formal knowledge to be good quantitative developers. This chapter, which represents a transition from the business requirements to the technical aspects of platform design, recapitulates the basics of computing and programming, all with a view to bridging the gap in technical knowledge in some of us so that we can come up with a robust design and sound implementation strategies.
The first order of business in designing a trading platform is likely to be technical choices ...
