This is episode two of the trading series. Here I write a logging library with an accompanying text logger implementation. Note, there are dozens of ways to incorporate logging. Some people use third party libraries, others build entire tools outside their main application to handle logging. can use a third party logger If you’d like, or build a conpletelt seperate tool outside the Trading Engine application for logging. I decided to write my own library for several reasons: a) we want it to be dependency injection friendly b) other text-based logger libraries are rigid and one cannot customize the format we'd like to emit the log in, and c) the whole point of this series is to learn how to write code in the context of building a trading application. Prop firms don't often rely on other people's code for something as critical as text logging. Some exceptions may be trace logging which are non-ascii based logs (binary logs). Some useful public libraries for tracing exist, for example in C++: https://github.com/morganstanley/binlog. Given that this is a series where we're meant to learn, instead of copying other people's code, we'll probably write our own tracing library as well when we need it.
