Overview of TZ-Pivot Logic

The TZ-Pivot script is a specialized technical analysis tool designed to automatically project significant price levels—such as Pivot Points, Fibonacci retracements, and Camarilla levels—onto your trading chart. Its unique selling point is its ability to handle complex time zone differences, allowing it to calculate these levels based on specific global trading sessions (like the London or New York sessions) regardless of your personal local time or the broker's server time.

Core Functionality

1. Intelligent Time Zone Synchronization

The primary logic of this script revolves around "Time Zone Mapping." Unlike standard indicators that simply look at the current day, this tool allows you to input:

Local Time Zone: The time zone your trading platform is currently displaying.
Destination Time Zone: The time zone of the market session you want to analyze.

The script performs the math necessary to "travel" between these two zones. It identifies exactly when a trading day started and ended in your target location, ensuring that the high, low, and closing prices used for calculations are accurate to that specific global market.

2. Data Collection and Analysis

Once the correct time window is identified, the script scans the historical data to extract three key metrics from the previous day:

Yesterday’s High & Low: The extreme price points reached.
Yesterday’s Close: The final price at the end of the session.
Today’s Open: The starting price of the current session.

3. Automated Level Calculations

Using the data collected above, the script dynamically draws several types of professional trading levels:

Standard Pivot Points: It calculates a central "Pivot" line and identifies Support (S1, S2, S3) and Resistance (R1, R2, R3) levels based on the previous day's range.
Fibonacci Levels: It projects specific percentages (38.2%, 50%, and 61.8%) of the previous day's price range to highlight potential areas of support or reversal.
Camarilla Breakout Levels: It calculates H3, H4, L3, and L4 levels, which are frequently used by scalpers to identify breakout points in volatile markets.
Mid-Point Pivots: For more granular analysis, it can draw the exact halfway points between major resistance and support levels.

4. Visual Presentation & User Experience

The script is designed for clarity on the chart:

Dynamic Labeling: It places text labels directly on the lines (e.g., "R1", "S2") so you can identify them instantly.
Information Dashboard: A real-time comment box in the corner of your screen provides a snapshot of the current session's range, highs, lows, and closes in pips.
Customizable Visibility: You can toggle specific features on or off (like showing only Fibonacci levels or hiding certain labels) to keep your chart clean and focused on your specific trading style.

Summary for the Trader

In essence, this script removes the manual math of "converting time zones" and "calculating pivot formulas." You simply tell it which market you want to follow, and it automatically paints the roadmap of key price boundaries for that session, helping you identify where the market might find support or face resistance.

/* 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 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.
