This code is part of Project Mencator. This particular module is responsible for gathering input data using the FMP and Polygon.io. Keep in mind that this project is intended for MacOS users. If you would like to implement this project to a different operating system, feel free to fork the repository and make the necessary changes.

The dependencies can be installed using dependencies.sh which is located in the root directory of the project. You can run the script by executing the following command:

./dependencies.sh

chmod +x dependencies.sh

First, clone the repository:

git clone https://github.com/Roiqk7/Data-Fetcher.git

Afterwards navigate to the project directory:

cd Data-Fetcher

Then install the dependencies by running the dependencies.sh file:

./dependencies.sh

chmod +x dependencies.sh

Now you can build the project by executing the build.sh file:

./build.sh

chmod +x build.sh

Note: You do not have to build the project if you only want to use it as a library. Building the project is only necessary if you want to run the tests or want to contribute. In order for the tests to run, you need to add your API keys into src/include/constants.h.

Include the library in your C++ project by including the header file:

#include <dataFetcher/dataFetcher.h>

Then, you can use the functions provided by the library:

Json::Value fetchHistoricalData(const std::string& tickerSymbol, const std::string& fromDate, const std::string& toDate,
                const std::string& timeFrame, const std::string& api, const std::string& apiKey);
Json::Value fetchHistoricalData(const std::string& urlString);
Json::Value fetchHistoricalData(const std::string& urlString, const std::string& apiKey);

These functions will allow you, the user, to fetch historical data of a given stock/etf in a given period of time with a desired time frame. The programme supports the FMP and Polygon.io APIs. The function will return a Json::Value object that contains the fetched data. Browse the documentation for more information.

If you need to run the tests, you can do so by running the following command:

./FetcherTests
