New article Extending MQL5 Standard Library and reusing code has been published at mql5.com:
MQL5 Standard Library makes your life as a developer easier. Nevertheless, it does not implement all the needs of all developers in the world, so if you feel that you need some more custom stuff you can take a step further and extend. This article walks you through integrating MetaQuotes' Zig-Zag technical indicator into the Standard Library. We get inspired by MetaQuotes' design philosophy to achieve our goal.
In a nutshell, MQL5 API is intended for you to benefit from code reuse, reliability, flexibility and easy maintenance. This is what the theory says, but beyond all this, if you plan to continue to advance in MQL5 to develop more sophisticated things, such as multi-currency Experts Advisors, you should first be able to code in the Standard Library way so that your apps are guaranteed a successful life. As your EAs and indicators become more and more complex, it is more necessary to master the concepts involved in a framework development. As a real life example, it is my personal need to develop a complex multi-currency EA which dictates the need of strengthening the base of my project from scratch.
