EvgeTrofi:

If return has a lot of brackets - it starts getting confused!?

Here, for example, is a function that returns a number from a string like "klsfd Step 2:

How is it different from this one?

The second one will cause compile-time problems, while the first one won't.

Try this

int GetStep(string text){
   string Right;
   int U = StringFind(text, "Step ");
   int End;
   if(U>=0){
      U=U+5;
      Right = StringSubstr(text, U);
      End = StringFind(Right, ".");
      return((int)(MathRound(StringToDouble(StringSubstr(text, U, End-U)))));
   }
   return(0);
}

Interesting:

You need to explicitly convert the result to the int type.

PS

But as I understand this warning can be ignored in principle...

Well it is clear, but logically it is not correct! An expression to the right of the equality sign should return the int type!

It is int for SYMBOL_TRADE_STOPS_LEVEL but the function may return other types as well...

Identifier	Description	Property type
SYMBOL_SELECT	Indicates that the symbol is selected in the Market Watch	bool
SYMBOL_VOLUME	Volume - Volume of the last trade	long
SYMBOL_VOLUMEHIGH	Maximum Volume for the day	long
SYMBOL_VOLUMELOW	Lowest Volume for the day	long
SYMBOL_VOLUMEBID	Volume in current Bid	long
SYMBOL_VOLUMEASK	Volume in current Ask	long
SYMBOL_TIME	Last Quote Time	datetime
SYMBOL_DIGITS	Number of decimal places	int
SYMBOL_SPREAD	Spread size in pips	int
SYMBOL_SPREAD_FLOAT	Sign of a floating spread	bool

PS

Besides, as I've already written above, this warning can be "ignored" if you can be sure that the code is correct...

Can you please tell me how to turn off the automatic update? My workplace only gives me 200 MB for a month. One more update and the traffic goes down :(

Standard ways are not possible, at least not yet...

"updated" to the latest build - as a result, each time you connect to the Internet, the client at first consumes 60 mb, then does not respond, forced to close the

client through the task manager, opened the program "defragmentation disk This section of the drive (where the client is installed) is very fragmented, defragmentation

still does not help, files in the directory (where the terminal MQL-5 is installed) are still fragmented.

I rewrote my EA from MQL4 to MQL5. When compiling - does not make a single error or comment. During testing - not a single trade. Where can I find the reason for this result? What should I look for first?

Can I see the log of the Expert Advisor in the Strategy Tester (preferably as a file)?

[Evgeniy Trofimov]

The log is, you could say, blank. I'm used to MQL4 writing like wrong lot or wrong stops....

This is the tester's log, with an indication of where to look at the agent's log
