write to file

New comment
 

I am trying to get a simple script to write the values of the technical indicators to a text file but I do not get the right values.  The output file dates are integers


void OnStart()
{
   int file_handle=FileOpen("h1.csv",FILE_READ|FILE_WRITE|FILE_CSV);
   
   double   macd_buff[]; // array of indicator values
   datetime date_buff[]; // array of indicator dates

   ArraySetAsSeries(macd_buff,true);
   int copied=CopyTime(NULL,0,0,1000,date_buff);
   ArrayResize(macd_buff,copied);   
   for(int i=0;i<copied;i++)
   {
      macd_buff[i]=iMACD("GBPUSD",PERIOD_D1,12,26,9,PRICE_CLOSE,MODE_MAIN,i);
      FileWrite(file_handle,date_buff[i]);
      FileWrite(file_handle,macd_buff[i]);
   }
   FileClose(file_handle);
}
 
jshumaker:

Dates will show up as integers unless you convert them to strings.

As per the documentation:

The datetime type is intended for storing the date and time as the number of seconds elapsed since January 01, 1970. This type occupies 8 bytes of memory.
Look at TimeToString() for MQL5 or TimeToStr() for MQL4.

  1. macd_buff[i]=iMACD("GBPUSD",PERIOD_D1,12,26,9,PRICE_CLOSE,MODE_MAIN,i);
    Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section, (bottom of the Root page?)

    Next time post in the correct place. The moderators will likely move this thread there soon.

  2. TimeToString

  3.       FileWrite(file_handle,date_buff[i]);
      FileWrite(file_handle,macd_buff[i]);
    You want to create a CSV file, rows of data with two columns. You are currently creating a one column file. Use one FileWrite.
