Developing a trading Expert Advisor from scratch (Part 21): New order system (IV)
In the previous article, Developing a trading Expert Advisor from scratch (Part 20), we considered the main changes that need to be made to get the visual system of orders. However, further steps required more explanation, so I decided to split the article into several parts. Here we will finish making the main changes. There will be quite a few of them, but they are all necessary. Well, the whole work will be quite interesting. However, I will not complete the work here, because there is still something left to do to really finish the system. Anyway, by the end of this article, the system will have almost all the necessary functionality.
