/* 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)
LocalTimeZone: 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 :-)
