// This "indicator" calls DLLs to fetch a special XML file from the 
// ForexFactory web site.  It then parses it and writes it out as a .CSV 
// file, which it places in the folder: experts/files so that IsNewsTime() 
// can use that file to tell if it is near announcement time.
//
// It does this once when it starts up and once per 6 hours in case there  
// have been any updates to the annoucement calendar.  In order to lessen 
// sudden traffic on the FF site, it refreshes every 6 hours on a random 
// minute.
//
// SAMPLE CALLS TO THE INDICATOR:
//
//     int minutesSincePrevEvent = 
//            iCustom(NULL, 0, "FFCal", true, true, false, true, true, 1, 0);
//
//     int minutesUntilNextEvent = 
//            iCustom(NULL, 0, "FFCal", true, true, false, true, true, 1, 1);
//
//     // Use this call to get ONLY impact of previous event
//     int impactOfPrevEvent = 
//            iCustom(NULL, 0, "FFCal", true, true, false, true, true, 2, 0);
//
//     // Use this call to get ONLY impact of nexy event
//     int impactOfNextEvent = 
//            iCustom(NULL, 0, "FFCal", true, true, false, true, true, 2, 1);
//
//
// EXAMPLE CODE FOR USE IN AN EA:
// (NOTE I HAVE PUT IN CODE TO CALL THE INDICATOR ONLY ONCE PER MINUTE)
//
// // EA Setting variables
// extern int MinsBeforeNews = 60; // mins before an event to stay out of trading
// extern int MinsafterNews  = 60; // mins after  an event to stay out of trading
//
// // Global variable at top of file
// bool NewsTime;
//
// // Function to check if it is news time
// void NewsHandling()
// {
//     static int PrevMinute = -1;
//
//     if (Minute() != PrevMinute)
//     {
//         PrevMinute = Minute();
//    
//         int minutesSincePrevEvent =
//             iCustom(NULL, 0, "FFCal", true, true, false, true, true, 1, 0);
// 
//         int minutesUntilNextEve nt =
//             iCustom(NULL, 0, "FFCal", true, true, false, true, true, 1, 1);
// 
//         NewsTime = false;

//                             OTHER CREDIT DUE
//      (For GrebWeb and LogUtils functionality (see end of this flie)
//
//  2/14/2007:  Robert Hill added code for using text objects instead
//              of Comment() for easier reading
//
//  2/25/2007:  Paul Hampton-Smith for his TimeZone DLL code
//  3/31/2007:  Code replaces by simpler method from BurgerKing
//
//  2/26/2007:  Mike Nguyen added the following things: 
//              (search text for "Added by MN")
//
//            - Connection test so that MT4 doesnt hang when 
//              there is no server connection                 
//            - Fixed some minor syntax because was getting 
//              "too many files open error..."
//            - Added vertical lines and vertical news text so that 
//              we have a visual reference of when the news happened.
//            - Now supports and correctly draws two simultaneous news 
//              announcements
//            - Added text to say "xx min SINCE event..." after the 
//              event as past
//            - Clean up old Objects left behind on old news annoumcents
//            - Now "Back Draws" Old news headlines onto the chart
//            - Now can choose which corner of the chart to place the 
//              headlines
//
//  4/2/2007:  Mike Nguyen added the following things: 
//             (search text for "Added by MN")
//           - Added ability to disable Web/URL updates. This is so that the 
//             multiple instances of the indicator used by other charts or EAs
//             dont fight with each other (Error code 4103)
//           - Fixed deleting OBJ_TREND, only deletes its own Trend Lines 
//             objects instead of all OBJ_TREND objects
//           - Fixed deleting OBJ_TEXT, only deletes its own Headlines 
//             instead of all text
//           - Made file name global and indicator now deletes the xml file  
//             each time the indicator is put on or removed from chart. Fixed 
//             one case of divide by zero where multiple charts indicator is 
//             on was trying to overwrite the same file (forces a new 
//             download of the xml)
//
// 4/29/2007:  Derk Wehler
//           - Fixed problem where indicator returns zero for "Minutes Until 
//             Next Event" when there are no more events for the week for 
//             that currency pair.  That caused EAs calling it to think that
//             it was always new time.  Instead, we now set it to a flag
//             value, which EAs can test for.
//
// 5/16/2007:  Derk Wehler
//           - Added sample code to header
//           - Changed variable name from DispOldNews to DispVertNews
//
// 6/02/2007:  Derk Wehler (thanks to "Flourishing")
//           - Changed how often it updates the file from the FF site web 
//             page.  Now it uses a global variable, so that when you have 
//             it running on multiple charts, it should only update once 
//             every 4 hours for all of them.
//
// 6/05/2007:  Derk Wehler
//           - Fixed logHandle error by resetting to -1 when closed
//           - Added "NeedToGetFile" variable for getting the XML if it 
//             does not already exist
//           - Added extern "SaveXmlFiles", so that when FFCal de-inits, 
//             the user can choose whether or not to delete old XML files

/*
		IDEAS FOR ADDITIONS:
		
*   A text lable of what the news was and when it was, e.g
    "USD CPI m/m @ [broker time here]" at the top or bottom within the shaded area.
    
*   Label the number of pips it went in its initial direction and how much it 
	retraced...of course you'd have to come up with a convention for measuring 
	movement.  Or you could label what price was just prior to news then labels 
	the next two price exteremes.  I think it would be nice to have the numbers 
	right under/over the candle that produced the extremes for whatever timeframe 
	you are in.

*   Label the volume count for the candle that included the news in it...whatever 
	timeframe your in.  So I could switch from 1 min. to 5 min. to 15 min. 
	timeframes and get different vol. counts for the bar that included the news.
