Pairs Trading Strategy Implementation in C++

Two CSV files (one per stock) with the following header:

Ticker,GE US Equity
DATE,PX_LAST

(replace "GE US Equity" with the desired ticker) followed by a list of rows containing a date and a closing price each.

Paths to the above files, along with trading band values, must be set in the main function body. The commented section in main may be used to find a set of band values using brute force (not really elegant). A cointegration test is recommended to find the ideal stock pair.

Pairs trading is a fairly simple (and wildly known) trading strategy, and that is nice to learn because of the concepts you need to know to understand it. My implementation does not take transaction costs into account, and that is one of the reasons you may get positive returns while playing around with it.

The code for this project is also way more complicated than it could potentially be. The idea was to force me to use some design patterns in C++, that I didn't necessarily need, but wanted to learn how to implement.
