Calendar :

Author: fxsaber

Thanks fxsaber,
This library is so great.
May I ask would the.bin file be readable by notepad++? The file created by my EA is not readable by notepad++, and during BT, the calendar.Load returns nothing. Do you have any hint on this?

Thanks

It is better to immediately formulate what the task is.

Sorry fxsaber, let me clarify.

Basically, I start with the example code you shared, I am able to download and create a .bin file.

I am trying to code the below for Backtest, objective is to load the .bin in every iteration, so as to check for news/events of each currency listed in the class.

However, when I am doing backtesting, The Calendar.ToString returned blank.(the "Print" are for debugging)


thanks, 

 if ( MQLInfoInteger ( MQL_TESTER )) 
 {
    NF_Stopped_CCY="";  
      for(int i=0;i<8;i++)        
        {
                Calendar.Load(CALENDAR_FILENAME);
                Print("Raw",Calendar.ToString(0,10,false));  

                Calendar.FilterByTime(TimeCurrent()-NF_Stop_in_Days*24*60*60,TimeCurrent()+NF_Stop_in_Days*24*60*60);
                Print("FilterByTime",Calendar.ToString(0,10,false));  

                Calendar.FilterByCurrency(CCYP[i].Cname);
                Print("FilterByCCY",Calendar.ToString(0,10,false));  

                Calendar.FilterByImportance(NF_Stop_Importance);  
                Print("FilterByImp",Calendar.ToString(0,10,false));  
 
                          
                CCYP[i].Stop_By_News=Calendar.GetAmount();
                if (CCYP[i].Stop_By_News) 
                {
                  int temp=StringConcatenate(NF_Stopped_CCY,NF_Stopped_CCY," ", CCYP[i].Cname);
                  Print(Calendar.ToString(0,-1,false));  
                }
        } 
   Print("NF list(BackTest)   :",NF_Stopped_CCY);
   NEWS_RefreshTime.day =CurrentDay.day;
  }

You only need to load the data from the file into a static variable once.

#define  CALENDAR_FILENAME "Calendar.bin" // File name for reading/writing the Calendar.
#property tester_file CALENDAR_FILENAME  // Specifies that MT5-Tester picks up this file.

#include <fxsaber\Calendar\Calendar.mqh> // https://www.mql5.com/ru/code/32430

CALENDAR CalendarFull; // Object with calendar data.

int OnInit()
{      
  return(CalendarFull.Load(CALENDAR_FILENAME) == -1); // Load events from the file
}

void OnTick()
{
  CALENDAR Calendar = CalendarFull;
  
  //....
}

Thanks a lot, it is nice and precise.

Thanks fxaber,

I was able to tidy up the code with your suggestion, but still, the CalendarFULL is also empty after loading the .bin.

the CalendarFULL.Load does return a "1", but there seems nothing inside CalendarFULL.

Would it be some sort of encoding issue of the .bin?

THanks

Run this script once in the MT5-terminal to generate the bin-file.

#define  CALENDAR_FILENAME "Calendar.bin" // File name for reading/writing the Calendar.

#include <fxsaber\Calendar\Calendar.mqh> // https://www.mql5.com/ru/code/32430

void OnStart()
{
  CALENDAR Calendar;

  if (Calendar.Set(NULL, CALENDAR_IMPORTANCE_NONE, 0, 0)) // Loaded absolutely all events (history + future) from MT5-Terminal.
    Calendar.Save(CALENDAR_FILENAME);                     // Save them to a file.
}

Thanks fxsaber, I did that and it did generate a 7xmb .bin file. However, still once I attempt to load and print out, it returned blank.

Thanks fxsaber,

Eventually, I found out the problem with my code, my .mq5 was saved as Unicode somehow, that made the fileread didnt work, once I change it to ANSI, it works.


Thanks,
