This script is designed to automate the calculation and visualization of several important technical analysis levels—specifically Pivot Points, Fibonacci retracements, and Camarilla levels—based on specific time zones. Instead of using a fixed set of dates, it dynamically identifies "yesterday" and "today" based on the geographical time zone you provide, making it highly adaptable for global traders.

Core Logic and Functionality

1. Time Zone Intelligence The script distinguishes between your computer's local time (or the broker's server time) and a specific destination time zone. This allows you to calculate trading levels for a different market (e.g., viewing London session levels while based in New York). It handles the complexities of searching for the correct "trading days," even accounting for weekends and gaps in data.

2. Automatic Data Collection Once the correct time zones are identified, the script scans the price history to automatically extract four key pieces of information from "yesterday":

  • The highest price reached (High)
  • The lowest price reached (Low)
  • The closing price (Close)
  • The opening price (Open)

It also tracks the high and low of the current day in real-time.

3. Technical Level Calculations Using the data gathered from the previous day, the script calculates a variety of support and resistance markers:

  • Standard Pivot Points: Calculates the central Pivot and three levels of Resistance (R1, R2, R3) and Support (S1, S2, S3).
  • Midpoint Pivots: Provides additional "halfway" points between the main pivot and its support/resistance lines for more granular analysis.
  • Fibonacci Retracements: Automatically projects key Fibonacci percentages (38.2%, 50%, and 61.8%) based on the range of yesterday's price action.
  • Camarilla Levels: Calculates specific technical levels (H3, H4, L3, L4) often used by day traders to identify potential breakout points.

4. Visual Interface & Customization The script translates these complex mathematical calculations into clear visual elements on your trading chart:

  • Dynamic Lines: It draws horizontal lines for all calculated levels and vertical markers to show exactly where "yesterday" started and ended.
  • Labels: It places text labels (e.g., "R1", "Pivot") on the lines so you can identify them at a glance, including the specific price value if enabled.
  • Live Dashboard: It generates an on-screen comment in the corner of the chart that summarizes the current range (in pips), today's highs/lows, and yesterday's closing data.

5. User Control The logic includes several "toggle" switches that allow you to customize your view:

  • Choose which specific levels to display (Pivots, Fibos, Camarilla, or Midpoints).
  • Adjust visual styles like line thickness and color.
  • Toggle the visibility of price labels or the summary dashboard.

/* 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.
