yosuf:
Can you please tell me if the indicators H-L, H-O, H-C, O-C, O-L are available, preferably with lines of their mean values? Google sent me a link which I don't quite understand: http://www.metatrader4.com/ru/forum/8261/. I think they would be useful for assigning optimum TA and SL.

So, what's the problem? Replace Close in any indicator with a difference (High-Low) or any other of these. However, in some cases, you may have to draw the indicator in a separate window.

In which indicator, exactly, is it better to change? Aren't they still available in a separate form?

In 2 words. The script is designed to delete graphical objects from the client terminal window. The script can be used in one of 2 ways: either all objects are deleted or the script goes through a series of objects and deletes only the ones selected by the user.

Question: why in the while loop after the next object is deleted the last Alert("Object ",obj_name," successfully deleted") function doesn't show the corresponding message on the screen and doesn't show up in any way (though the object is deleted in the while loop)

Note: the line with the include file #include < WinUser32.mqh> in the header of the script, which differs from the original include file #include <WinUser32.mqh>, supplied with the client terminal, so it is also given below

P.S. In order not to litter the forum, thank you in advance for your reply

yosuf:
Which indicator, exactly, is the best one to replace? Aren't they still available in a separate form?

The MA, for example, has it, but there are few options and the ones you mentioned are not there:

Therefore, you can take almost any indicator and make its versatility yourself.

      Alert("Объект ",obj_name," успешно удален");                //сообщение об успешном удалении

This is because if(error != 0) will only affect an Alert, after which it will always continue and the next Alert will never be invoked

Hello! Please tell me how to make a loop counter (e.g. FOR) to search for orders within the current day!

What can I say I do not understand anything yet, I understand only one thing that it is all about making money, why do advisors if they are losing, you can go to the platform once a week and earn 1000 in a deposit of 3000

kamolot: What are EAs for if they are losing money, you can log on to the platform once a week and earn 1000 on a 3000 deposit.

They just do not have the guts to stop by the platform even once a week and earn a grand. They are all too tired just to make money.

GaryKa:
It's just that these labyrinthine programmers don't have the heart to come in even once a week and earn their schtick. They're all too tired to make any money.
