Any new subject seems complicated and hard-to-learn for a newbie. Subjects that we know seem very simple and clear to us. But we simply do not remember, that everyone has to study something from scratch, and even our native language. The same is with the MQL5 programming language that offers wide possibilities of developing one's own trading strategies - you can start learning it from basic notions and simplest examples. Interaction of a technical indicator with the MetaTrader 5 client terminal is consider in this article on the example of the simple custom indicator SMA.
This class library can be added to an MT5 Expert Advisor to enable it to be written with an order-centric approach broadly similar to MT4, in comparison to the position-based approach of MT5. It does this by keeping track of virtual orders at the MT5 terminal, while maintaining a protective broker stop for each position for disaster protection.
