"A library for easy and fast programme creation" ... . well... well...
 
Dmitrii Troshin:
"A library for easy and fast programme creation" ... . Well... well... well...

What's wrong with that? At the moment, the creation of the library is described, not a quick and easy way to create programmes with it. Everything will be.

Before one person can get quick and convenient access to any data, someone else must first work hard and organise the availability and accessibility of all the required data. Or do you disagree with this statement?

 

I may be wrong, of course, because I'm not the first instance.

but in my opinion because of the fact that the cycle of articles by its volume is already catching up with the famous work of L.Tolstoy it is absolutely impossible to find in the articles ready implementation by search.

As an example, I decided to check my order volume normalisation function with those described in the article = search by author's message does not process the text of the article, I opened 3 articles selectively through browser search (Ctrl + F) and could not find them.



ZY: how to use this? - does anyone have any suggestions? - selectively to me a part of the ready material would be useful, to read all articles completely, imho, only in printed version is possible, so that there was a place to put pencil markings

It reminds me of a cartoon why the lion has a big mane. It turns out that on the fifteenth article the haircut has just begun :)

Well, you didn't read it. Then you just don't understand the whole idea of this series. This is a large training material, touching on many aspects of information required in different situations.
And in the end it will be a very simple access to ready-made data in the style of "ask - get".
Yes, it's a lot of material, and a lot of hard work. Is that a reason for irony and sarcasm?

I find by Ctrl+F, but I run through all articles.
And in the code it doesn't search that way.
But it's in DELib.mqh.
True, the function is not without flaws.

Upon completion there will be full reference information with examples. On the principle of SB help
 
Artyom Trishkin:
Upon completion, there will definitely be a complete reference with examples. On the principle of the SB reference

without such a reference your series of articles is of no practical use, imho

 
Igor Makanu:

Those who are interested and who need it are already asking questions. Unfortunately, most of them ask questions in private and Skype. No matter how much you ask them to ask questions in the discussion, they still knock on my contacts.
And the help and examples were planned right away - without them work is not work. I don't like to abandon what I've started, and I don't like hackwork either.
 

Artyom Trishkin:
Кто заинтересован, и кому нужно, те уже задают вопросы. Правда по большей части в личке и скайпе к сожалению. Сколь ни проси задавать вопросы в обсуждении - всё равно в контакты стучатся.

...

You - moderators, should seriously think about this interesting phenomenon - why do people avoid the forum?
