-------------------------------------------- MAIN MODIFICATIONS --------------------------------------------
------------------------------------------------------------------------------------------------------------

These modifications were applied to 03-17-2014 release founded here: 

    Added: #property strict for compatibility with MT4 Build 600+ and better code quality.
    Added: Show event Previous/Forecast. (colored impact)
    Added: Option to show events related to active chart only (override other parameters)
    Added: Keyword filter. Find or Ignore a specific one word, i.e. "NFP", will filter out all events with/without only that word. (case-sensitive)
    Added: Option to show currency strength / bar time left / spread value.
    Added: Option to control the time for display of past events  (in minutes).
    Added: Option to set panel location in 4 chart corners.
    Added: Tool-tip on mouse hover that shows event title, impact and event time left.
    Added: Panel title. You can use it as a reminder note :)
    Modified: Show event in "Date/Time format" instead of minutes left (you can show minutes left through Tool-tip)
    Modified: Vertical lines for the upcoming events. (You may need to modify the "time offset" input depending on your broker time).
    Modified: Buffers that holds the upcoming event minute and impact (see examples below)
    Modified: Revised order of external inputs.
    Improved: Replaced DownLoadWebPageToFile() function with native Windows URLDownloadToFileW() function.
    Improved: Placed (download/read XML file) and related codes into a functions so we can call them when needed.
    Improved: Replaced "GlobalVariables" that used to update XML file with FILE_MODIFY_DATE - OnTimer() set by "AllowUpdates", "UpdateHour" inputs.
    Improved: Time GMT offset, now the events will show in your local time automatically.
    Improved: Justify the panel/text when set to right/left.
    Improved: Alert function, Now it will send beside the Popup Alert: sound alert, Push notification and Emails. (two separate alerts)
    Improved: Code quality, now the indicator is lighter and faster than ever.
    Fixed: Various bug fixes, some unnecessary/unused codes or variables removed, placed some variables inside their related functions.

-------------------------------------------- HOW TO USE BUFFERS --------------------------------------------
------------------------------------------------------------------------------------------------------------

For use in an EA, the indicator holds 2 buffers: 
- Buffer (0) Contains minutes until the most recent event 
- Buffer (1) Contains impact value for the most recent event (Low = 1, Medium = 2, High = 3)

*Please note that the indicator will not work on strategy tester

------------------------------------------------- EXAMPLES -------------------------------------------------
------------------------------------------------------------------------------------------------------------
Simple call: 
-------------
NOTE: if you use the simple call method, default values will be applied 

int EventMinute = (int)iCustom(NULL,0,"FFC",0,0);
if(EventMinute == 30) { .. YOUR CODE .. } 30 minutes before the event

int EventImpact = (int)iCustom(NULL,0,"FFC",1,0);
if(EventImpact == 3)  { .. YOUR CODE .. } High impact event

Advanced call:
-------------
iCustom(
        string       NULL,            // symbol 
        int          0,               // timeframe 
        string       "FFC",           // path/name of the custom indicator compiled program 
        bool         true,            // true/false: Active chart only 
        bool         true,            // true/false: Include High impact
        bool         true,            // true/false: Include Medium impact
        bool         true,            // true/false: Include Low impact
        bool         true,            // true/false: Include Speaks
        bool         false,           // true/false: Include Holidays
        string       "",              // Find keyword
        string       "",              // Ignore keyword
        bool         true,            // true/false: Allow Updates
        int          4,               // Update every (in hours)
        int          0,               // Buffers: (0) Minutes, (1) Impact
        int          0                // shift 
        );

                                                                                  - Awran5, 08-14-2016
