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 curor 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. */ extern int LocalTimeZone= 0; extern int DestTimeZone= 0; extern int LineStyle= 2; extern int LineThickness= 1; extern bool ShowComment = false; extern bool ShowHighLowOpen = true; extern bool ShowSweetSpots = false; extern bool ShowPivots = true; extern bool ShowMidPitvot = true; extern bool ShowFibos= false; extern bool ShowCamarilla = false; extern bool ShowLevelPrices = true; extern int BarForLabels= 10; // number of bars from right, where lines labels will be shown extern bool DebugLogger = false; /* The following doesn't work yet, please leave it to 0/24: TradingHoursFrom: First hour of the trading session in the destination time zone.
