Try to dance from here: "Can you tell me how to find the price of the last fractal?
example:"sergeev: The iFractals indicator can be used for that. It returns 0 if there is no fractal on the bar and the value of the fractal price if there is one. Fractals are divided into upper and lower fractals. If you need to get the higher ones, MODE_UPPER is passed into the iFractals function, and MODE_LOWER for the lower ones. Therefore, to find a fractal, you should loop through the bars and the first non-zero value will be the fractal you are looking for.
The documentation says that the iCustom function should be used to call third-party indicators.
The second parameter in this function is timeframe. If I have this parameter in an indicator, and it will be specified in theiCustom function parameters, there is a place after the name parameter to enter the list of parameters passed by the indicator.
So. I will pass the timeframe parameter from the indicator in any case. If we specify the same parameter in 2 places, it is not logical. Then what is the right way to proceed?

Everything is in order. Everything must be specified. The second parameter is the TF where the indicator is physically attached, the custom TF is where the indicator takes data for the calculation. Of course, you can remove the second parameter from the indicator code, if there is logic in this.
I see now. Thank you.
But the same parameters that should be set in the indicator should be declared in the EA. It turns out that all the parameter values for the correct joint operation of the indicator and the Expert Advisor should be defined equally in both cases?
If I have entered the variables in iCustom and have not declared them in the EA, then on compilation the journal will state that those variables that I have entered are not declared.
Who knows in which Code Base EA can I see how the OrderCloseBy() function is coded with all the pies. Watched the closeby script in the tutorial, but can't figure out how to make it a function to call from EA, etc. Maybe you can teach me what to do! Thank you!
Have you seen it here? https://docs.mql4.com/ru/trading/OrderCloseBy

Of course I did! I understand the principle, but it doesn't work, and I need to use the opportunity to save on the spread. That's why I wanted to see examples that work. I am looking through Code Base, but so far with no success. No one uses this mutual closing in these EAs. I hope to meet them assembled and not by the screws. Good night! Might be wiser in the morning!
Can you tell me how to delete trend lines, indicators, etc., on a normal computer on the Windows I did it with the right mouse button after selecting them, but on the imac I don't know how. And i also can't find how to add gold to the common list ?
Good afternoon. PEOPLE, ANSWER THE QUESTION PLEASE (3rd time posting). Question about a file index... In my MQL4 book, found at MQL4.community, in the "Standard Functions" section, there is an example of the script "File Operations", which is intended for reading data from a file and displaying graphical objects in a symbol window:
Below, when analyzing this script in the Book on MQL4, the following phrase is given: "if the specified check (the last 2 lines in block 5-6) is removed, an extra object will be created at runtime. And only after that, the while loop's termination condition will trigger and control will be passed to block 8-9".
Do I understand it correctly? A file pointer is NOT INFLOWED BY TEXT SIGNS (for example: text| where | is a file pointer), but is a pointer WITH EXPRESSION, for example: text where k is the "to" character, k-th is highlighted by a file pointer. This explains the need for strings (see p.164):
Indeed. On penultimate iteration, after creating LAST object
2007.05.11 18:30;JPY
the file pointer is at the position of the last object, i.e:
2007.05.11 18:30;JPY IndustrialManufacture
(where o is the "o" character, k is the file index). Then when passing control to while statement header, FileIsEnding(handle) function will obviously return true, because file pointer is NOT at end of file, but at LAST character of that file. Then when the first two lines are executed, the file pointer will move to empty space and if there are no lines
the script will create a graphic (i.e. a line) with an empty description and a time coordinate that corresponds to 0. This is what is meant in the phrase: "if the specified check (the last 2 lines in block 5-6) is removed, then an extra object will be created at runtime. "
Question: do I understand correctly:
a) the definition of a file pointer;
b) the meaning of the phrase "If the specified check (the last 2 lines in block 5-6) is deleted, then an extra object will be created at program execution.And only after that the while loop's end condition will be triggered and control will be passed to block 8-9".
P.S. In order not to litter the forum, thank you in advance for your answer
