Now that we have the list of stock symbols that we’ll work on, let’s use this information to load the data from file and store it in our newly declared dynamic arrays. The prototype of our main loop should look like the following listing. Listing 5.6 Reading stock data from a file using a read_stock subroutine ❶ For […]

Array constructors will come in handy to initialize the stock symbols. If we do it correctly, looping over them and printing each one to the screen, the output will look like this: As you can imagine, specific symbols depend on what data we have. Since in this exercise we’ll work with only 10 stocks, we […]

In chapter 2, we covered the basic declaration of arrays when implementing the minimal working version of our tsunami simulator: ❶ grid_size is the integer size of array h. When you specify the size of the array in the declaration line, you tell the compiler to declare a static array. The array size is known at […]

Before we do any data analysis, we need to take care of the logistics. These steps will generally apply to each of the three challenges in this exercise: To start, we can estimate the performance of different stocks by calculating their gain over the whole period of the time series data–from January 2000 to May […]

The full code for the stock analysis exercise is available as a GitHub repo at https:// github.com/modern-fortran/stock-prices. If you use git, you can clone it directly from the command line: Otherwise, you can download it as a zip file from http://mng.bz/OMZo. The repository already includes the stock price data needed for this exercise in the data directory. However, if […]

In this chapter, we’ll work on daily stock price time series from 10 technology companies, including Apple, Amazon, and Intel. The data is stored in the comma-separated value (CSV) format. Here’s a sample of the Apple stock daily data: The columns in each CSV file are For a birds-eye view of how these stocks performed […]

In this section, we’ll set tangible goals for this exercise: Before we dive into implementing the solutions to these challenges, let’s get familiar with the data that we’ll work with.

We’ll learn how Fortran arrays work in a real-world application–analyzing stock price time series. This has been an increasingly popular topic since the early days of computer programming, and Fortran has been used in the bowels of many trading and banking systems, mainly thanks to its robustness, reliability, and efficiency. In this chapter, we’ll work […]
