EJ_Pivot_DWM_v1

This script is designed to automatically calculate and display various technical analysis levels on a trading chart. It specifically focuses on identifying "Pivot Points," which are used by traders to predict potential support (price floors) and resistance (price ceilings) based on historical price action.

Here is a breakdown of the logic used by the script:

Core Functionality

The tool works by looking at historical price data—specifically the high, low, and closing prices from previous periods. Depending on your settings, it identifies these levels to help you visualize where the market might struggle to move upward or downward.

Key Features and Calculations

1. Standard Pivot Points The script calculates several classic pivot levels:

  • Main Pivot (P): The central balance point calculated from the previous period's high, low, and close.
  • Resistance Levels (R1, R2, R3): These represent potential areas where price may face selling pressure.
  • Support Levels (S1, S2, S3): These represent potential areas where price may find buying interest.

2. Camarilla Levels When enabled, the script calculates "Camarilla" levels. These are a specific type of pivot calculation often used by day traders to identify breakout points and reversal zones within a single trading session. It includes specific high (H3, H4) and low (L3, L4) markers.

3. Midpoint Pivots The script can also calculate intermediate "Midpoints" (M0 through M5). These act as smaller sub-levels between the main resistance and support lines, allowing for more granular analysis of price movement within a specific range.

Visual Elements and User Experience

  • Automatic Drawing: The script automatically draws horizontal lines across your chart at these calculated prices. It also places text labels (like "R1", "S1", "P") so you can easily identify what each line represents.
  • Dynamic Updating: As new price data arrives, the script updates these levels to reflect the most recent information.
  • Information Overlay: The script provides a small text summary on the chart showing the current high, low, and range of the previous day, giving you a quick reference for the market's volatility.
  • Timeframe Control: You can specify which timeframe the script should pull data from (e.g., Daily, Hourly, etc.), allowing you to see different types of structural levels on the same chart.

Operational Constraints

To ensure accuracy, the script includes a check to make sure it is not used on timeframes larger than a week. If the timeframe is too broad, the script will provide an error message to prevent misleading calculations.
