 Introduction:
   Draw ranges for "Simple Combined Breakout System for EUR/USD and GBP/USD" thread
   (see http://www.strategybuilderfx.com/forums/showthread.php?t=15439)
   TimeZoneOfData: TimeZone for which MT4 shows your local time, 
                  e.g. 1 or 2 for Europe (GMT+1 or GMT+2 (daylight 
                  savings time).  Use zero for no adjustment.
                  
                  The MetaQuotes demo server uses GMT +2.   
   Enjoy  :-)
