Alexander Kharlamov:

Hello!

MT4 has a command if (IsTesting()

Is there an analogue in MT5?

I would like to ask you a couple of questions, thank you.

P.S. And another thing - in normal mode my Expert Advisor writes a log file, but if I run it in tester in MT5, I don't see it in the usual Tester folder, as it was in M4.

About the files:FileOpen help

The file is opened in the client terminal folder in subfolder MQL5\Files (or in case of testing, in folder_agent_testing\MQL5\Files). If FILE_COMMON is specified among the flags, the file is opened in the common folder of all the client terminals \Terminal\Common\Files.

For example data directory

C:\Users\KVN\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\MQL5\Files,

then the directories of the test agents (using agent #1 as an example) will be here:

C:\Users\KVN\AppData\Roaming\MetaQuotes\Tester\D0E8209F77C8CF37AD8BF550E51FF075\Agent-127.0.0.1-3000\MQL5\Files

Thank you, with the replacement of IsTesting immediately understandable, and the log file to sort out, in trade mode, I write the file, but in the test is not. (
 
Alexander Kharlamov:
Thank you, I understand everything at once with replacement of IsTesting, and I'll deal with the log file, in trade mode my file is written, but in the test it is not. (
In the Strategy Tester, just click on the "Log" tab, then right-click and select the topmost item on the context menu: "Open". This will launch the Explorer, which will immediately open the folder with the logs of the Strategy Tester.
 
Can you please tell me if I put one EA on 10 different charts or on 10 identical charts, but with different TFs, do I have to go to the properties of the EA on each chart and change the Magic number?

Thank you

Thank you
If you put it on different charts, most likely it will be ok. If you put it on the same chart with different TF, most likely it will not work correctly, but to get an exact answer to your question, you have to look at the code.
 
BlackTomcat:
To avoid the hassle of finding the logs folder, simply switch to the "Log" tab in the Strategy Tester, click there and select "Open" from the context menu that opens. This will launch the Explorer, which will immediately open the folder with the logs of the Strategy Tester.
I wrote not about the standard log that you're talking about. I create my own log and write in it what I need. in trade works in the tester does not create the file.

However you try to create the file - the files will be created inside the sandbox. How to find files:

TERMINAL_DATA_PATH will also help.

TERMINAL_DATA_PATH would also help!

Here it is like in MT5!!! )) found it! )) THANK YOU!

Was looking in the terminal folder and it's in the Tester folder ... but not the one in the Terminal folder!

 

Tell me, did I write the closing price indicator correctly or are there pitfalls I haven't considered?

#property indicator_chart_window
#property indicator_buffers 1
#property indicator_plots   1
#property  indicator_color1  clrRed
#property  indicator_type1   DRAW_LINE 

double Buffer[];

void OnInit()
{
  SetIndexBuffer(0, Buffer, INDICATOR_DATA); 
}

int OnCalculate( const int rates_total,
                 const int prev_calculated,
                 const datetime &time[],
                 const double &open[],
                 const double &high[],
                 const double &low[],
                 const double &close[],
                 const long &tick_volume[],
                 const long &volume[],
                 const int &spread[] )
{
  return(rates_total - prev_calculated + ::ArrayCopy(Buffer, close, prev_calculated, prev_calculated));
}
 
Can you tell me why this might be the case? :
//--- По отдельности

Fun_1();     // Работает
//----------------------
Fun_2();     // Работает

//--- Совместно

Fun_1();     // Работает
Fun_2();     // не Работает
//----------------------
Fun_2();     // Работает
Fun_1();     // не Работает
Fun_1() and Fun_2() are similar.
