Renat Akhtyamov:
Check out the codebase, there are a lot of experts out there. Examine one of them thoroughly and you'll understand. That your task can be programmed in no more than 30 minutes

depending on the task... there are templates, but they are so primitive :(

And I don't digest the porta-potties 😂

One thing I do know is that the more primitive a programme is, the less risk of failure is there. As in mechanics, the fewer parts, the more reliable the mechanism. So, the main thing is the balance between functionality and reliability.

I agree, I've already said it somewhere here, an Expert Advisor should contain the most important things needed to solve the problem, and everything else is just a pile of junk that takes up the computer's resources.

SanAlex:

Here's a quick one I made to open with buttons.

Thanks, I think I'll look into it, for starters.

[VVT]

Роман Жилин:

Thanks, I think I will study it first.

I do not recommend to fit the strategy to the EA, better the other way round. Alternatively, you could put together the necessary parts of other EAs to implement your strategy.

[MrBrooklin]

Роман Жилин:

Need the right direction for a newbie, I feel like I'm going around in circles

Guide-Forum-Stories-Compiler-Errors (and so on in a circle each time).

I think I learn something new, but I get the feeling I'm severely depressed, I cannot open even basic order when starting an EA. I need someone to shine a torch in the deepest part of the night with no paths. I'm still wandering as I've lost my way.

Completely program, on opening a trade when it starts and please clarify what's what. Help me out a lot.

Hello Roman!

There are two great articles for beginners that have helped me a lot:

Vladimir, thank you. I came across the first article but the second one is exactly what I need now.

Роман Жилин:

Vladimir, thank you. I stumbled upon the first article, but the second one is just what I need now.

Sincerely yours, Roman.

I am also actively using the MQL5 Reference (MQL5 Documentation tab on the MQL5 website). It contains almost all information. The only big disadvantage of this book - it is written for people who have basic knowledge of other programming languages, but not for beginners. For example, I still don't understand the sense of the constantly occurring phrase beginning with"Returns":

AccountInfoDouble

Returns value of double type of corresponding account property

Who returns, who does it return, where does it return to, why does it return? I still don't understand it.

Regards, Vladimir.
