/* Introduction:
Calculation of pivot and similar levels based on time zones.
If you want to modify the colors, please scroll down to line
200 and below (where it says "Calculate Levels") and change
the colors. Valid color names can be obtained by placing
the cursor on a color name (e.g. somewhere in the word "Orange"
and pressing F1).
Time-Zone Inputs:
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.
DestTimeZone: TimeZone for the session from which to calculate
the levels (e.g. 1 or 2 for the European session
(without or with daylight savings time).
Use zero for GMT
Example: If your MT server is living in the EST (Eastern Standard Time,
GMT-5) zone and want to calculate the levels for the London trading
session (European time in summer GMT+1), then enter -5 for
LocalTimeZone, 1 for Dest TimeZone.
Please understand that the LocalTimeZone setting depends on the
time on your MetaTrader charts (for example the demo server
from MetaQuotes always lives in CDT (+2) or CET (+1), no matter
what the clock on your wall says.
If in doubt, leave everything to zero.
