User is facing multiple issues with trading code and platform errors

Ihor Herasko:

The values of the shift and iy variables in the above code are not checked for array outliers. Therefore, everything is logical. Check their values before using them, the error will disappear.

And to be more specific, you should know how CountBars and TimeFrame variables are generated.

CountBars =400 and TimeFrame =30, are set statically, in external.

On M30 everything is fine, on M15 it flies out.

How do I check shift and iy for outliers?

   if(TimeFrame>Period()) 
     {
      ArrayCopySeries(santa1,5,Symbol(),TimeFrame);
      summ=CountBars+TimeFrame/Period();
      shift=0;
      for(int iy=0; shift<summ; shift++) 
        {
        if(iy>ArraySize(santa1))continue;
        if(shift>ArraySize(santa1))continue;
         if(Time[shift]<santa1[iy]) iy++;//вот эта santa1[iy] "array out of range"

         list[shift]=bufbuy[iy];
        }
     }

Maybe someone will take the time to look up where the error is.

Guys, tell me how to add data to a file on a new line

my write function:

void Write(string file,string text,bool print)
  {
   filehandle=FileOpen(file,FILE_WRITE|FILE_CSV,'|');
   FileWriteString(filehandle,text);
   FileClose(filehandle);
  }

this is what I send to it:

Write(subfolder+"\\"+string(TF)+"\\TS"+string(ts)+"\\"+string(st)+"_"+string(st2)+".txt",
                                 string(mv)+"|"+

                                 string(m1)+"|"+

                                 ,NoPrint);

I need to add more lines below it:

Guys, can you tell me why the advisor on Alpari often fails [Invalid volume], although the lot size does not exceed the maximum, trading from 23-45 to 1-00.

I attached the log, there is no such error on other brokers

I have taken the code from the example here and am dealing with it

I defined a method

bool CControlsDialog::OnEvent(const int id,const long &lparam,const double &dparam,const string &sparam){

        //....

}

It complains that it's already defined and has a body.

Question: where is it defined?

Try searching the terminal folder. I found the file ControlsDialog.mqh and in it OnEvent()

Good evening!

I am puzzling over how to add a universal (for different instruments) code to calculate the lot for a deal based on % of deposit.

I made it like this:

input double MaximumRisk=0.02;                  //Риск в сделке от депозита

{Lots = NormalizeDouble(((AccountBalance()*MaximumRisk)/((MathAbs(Price-SL))/Point)/((MarketInfo(Symbol(),MODE_LOTSIZE)*(MarketInfo(Symbol(),MODE_ASK)+Point))
-(MarketInfo(Symbol(),MODE_LOTSIZE)*MarketInfo(Symbol(),MODE_ASK)))),Digits);}

Price ( opening price) and SL (Stop Loss) are calculated separately.

For pairs where quote currency is in dollars (eg EURUSD), for index SPX500 and for gold - all correctly calculated, but for pairs where the dollar is the first in a quote (eg USDJPY) does not work.

Please, what am I missing?
