Discussing the article: "DRAKON visual programming language — communication tool for MQL developers and customers"
It looks very interesting, thanks.
Chat style console is not so good for me, but it is many interesting things there.
I found Flowgorithm is more for educational purpose than real world programming. Drakon is closer to what I'm looking for : closer to Grafcet which is not well known outside of France and Automation field but it's a gem ;) https://www.researchgate.net/profile/Paul-Baracos-2/publication/243782363_Grafcet_step_by_step/links/588b7e3d45851567c93c9cdb/Grafcet-step-by-step.pdf
I had been taught a long time ago in french engineering school (not computer science but tradional engineering field) by a teacher who was part of the comitee. Before learning it I had no interesting in coding and was almost last, with it I became first :)
Then I forgot about it since I was in traditional software engineering. After decades I realised there's no real modeling in traditional software engineering as nobody actually uses UML apart from drafts and I realise Grafcet or equivalent + a bit of UML could be a real way to be on par with other engineering fields. Like Drakon it is first aimed at specification but due to its simplicity and fractality it can easily map with code so much people think that SFC is equivalent to Grafcet whereas SFC is indeed derived from Grafcet it is only a coding language for a specific industry (automation) not meant for specification.
As said here "one of the main advantages of GRAFCET is the specification of hierarchical structures" https://www.sciencedirect.com/science/article/pii/S2405896319314387 and it is exclusively event driven so very suitable for trading algorithms ;)

Check out the new article: DRAKON visual programming language — communication tool for MQL developers and customers.
DRAKON is a visual programming language designed to simplify interaction between specialists from different fields (biologists, physicists, engineers...) with programmers in Russian space projects (for example, in the Buran reusable spacecraft project). In this article, I will talk about how DRAKON makes the creation of algorithms accessible and intuitive, even if you have never encountered code, and also how it is easier for customers to explain their thoughts when ordering trading robots, and for programmers to make fewer mistakes in complex functions.
This will not decrease the load of the programmer’s technical work, but at least they will understand your thoughts much better, and there is less chance that they will make mistakes in the first versions. These errors will have eventually to be corrected, which may require additional time (and/or money).
In general, DRAKON diagrams are beneficial both for programmers and customers who are unfamiliar with programming but have a very good understanding of how exactly they want their EAs to work.
To put it simply:
For me, graphics in the algorithms is an indispensable communication tool. When two people are interested in the result and are engaged in a dialog, it is better for them to speak the same language. The language of DRAKON diagrams is universal for specialists in any branch of knowledge if you understand it once.
