A quick refresher for the previous article in the News Trading Made Easy series. In part 1, we went through the concept of DST(Daylight Savings Time) and the various versions for different countries that essentially change their time zones by an hour ahead and behind during a financial year. This will change trading schedules for the related brokers using DST. The reasons for creating a database and the benefits were addressed. A database was created to store the news events from the MQL5 Economic Calendar with subsequent changes to the event time data to reflect the broker's DST schedule for accurate back-testing in the future. In the project files, an SQL script results in an Excel format was provided for all the unique events accessible through the MQL5 Calendar for all the different countries.

However, in this article, we will make a few changes to our previous code in part 1. Firstly by implementing inheritance to the existing code and upcoming new code, the previous news/calendar database will get a revamp into something more useable and practical. Additionally, we will tackle risk management and create different risk profiles to choose from for users with different risk appetites or preferences.
