Yedelkin:
I can't find my way around, where in the Reference does it say that in exchange execution a request should not contain TP/SL?

I don't remember that in the reference. But as far as I know it is true. It is more correct to say SL/TP as far as I understand on the exchange you have to put separate orders (having a certain type and specification).

In principle you can look at stock terminals like exactly, grey box or say in Quik

PS

This for example may be related to the law. As far as I know the US law requires stops to be marked in a certain way (and not otherwise).

For their wrong execution certain penalties are imposed. i can not say for sure, but those who traded on the NYSE (or similar exchanges) i think they should know exactly what and how.

Please tell me how to take the values of all iBands.

there is something useful here, but the editor didn't find it when compiling

"#include <GetIndicatorBuffers.mqh>"

Please advise where to place the file uploaded by the Expert Advisor. I tried it in MQL5/Files. The tester gives error 5004. The indicator finds the same file in MQL5/Files right away. What is error 5004?

Please read more:

A file with .txt extension. The request is like this

   int filehandle=FileOpen(fname,FILE_READ|FILE_ANSI,"\n");
   if(filehandle!=INVALID_HANDLE) Print("FileOpen: ",FileSize(filehandle)," bytes");
   else Print("Operation FileOpen failed, error ",GetLastError());

 

 

The error is

2012.05.09 21:14:14 Core 01 2011.01.01 00:00:00 Operation FileOpen failed, error 5004

The file is located in the MQL5/Files folder. Checked it 1000 times. And the tool loads it without any problems.

Build 642.

Each tester has its own file sandbox, the data file should be placed exactly in the sandbox of the tester, it is not very convenient, so it is better to place the data file in the common folder of all terminals, it is accessed through the FILE_COMMON flag.

The file located in the shared folder can be accessed both from the terminal and the tester.

The public folder can be opened from MetaEditor - File - Open public data folder.

Thank you, the download via FILE_COMMON was successful. The tester's sandbox did not work. But never mind. The developers should have simplified this process and let the Expert Advisors take the data files from the same folder where the indices are loaded from. And it would be nice if we could specify the path to the file in its name.

There's no way it worked through the tester sandbox.

It's been a long time since I've checked the file handling in the local tester sandbox. But before, to have access to the file from the tester, I had to put "read only" attribute on the file, because the tester cleared its sandbox before launching the Expert Advisor.
