Once PyCharm is loaded, you will need to create a project and choose an interpreter. As we previously discussed, you will need to choose a version of Python 3. At the time of writing this book, the most up-to-date version is Python 3.7.0, but feel free to start with a more recent version than this one. Once the project is open, you need to create a Python file that you will call buylowsellhigh.py. This file will contain the code of your first Python implementation.
