Step on New Rails: Custom Indicators in MQL5

www.mql5.com

I will not list all of the new possibilities and features of the new terminal and language. They are numerous, and some novelties are worth the discussion in a separate article. Also there is no code here, written with object-oriented programming, it is a too serous topic to be simply mentioned in a context as additional advantages for developers. In this article we will consider the indicators, their structure, drawing, types and their programming details, as compared to MQL4. I hope that this article will be useful both for beginners and experienced developers, maybe some of them will find something new.

Please edit your post (don't create a new post) and replace your code properly (with "</>" or Alt-S), or attach the original file directly with the "+ Attach file" button below the text box.

NB! Very important! DO NOT create a new post. EDIT your original post. An also remove all unnecessary white-space from your code.

Please change your topic subject to something meaningful.

I will not even read a topic just asking for "Help", and I am certainly not the only one.
