linie_wsparcia_oporu_v2

This script is designed for the MetaTrader platform to automatically identify and visualize key price levels on a trading chart—specifically "Support" (the floor) and "Resistance" (the ceiling). Instead of simply drawing static horizontal lines, the logic focuses on finding significant price extremes over a user-defined period of historical data.

Core Functionality

The script analyzes a specific range of previous candles (determined by the user) to find the absolute lowest and highest points reached during that timeframe. It then uses these points to construct visual trend markers on the chart.

1. Support Identification (The Floor)

  • Scanning: The script looks through the historical "low" prices of the candles within your chosen range.
  • Finding the Bottom: It identifies the single lowest price point reached during that period.
  • Trend Drawing: It then draws a trend line connecting these low points. The logic includes a "validation" step: as it draws the line backward, if any historical price falls below the current line, the script adjusts the line to ensure it accurately reflects the boundary of the price action.

2. Resistance Identification (The Ceiling)

  • Scanning: Similarly, the script examines the "high" prices of the candles in your chosen range.
  • Finding the Top: It locates the highest peak reached during that period.
  • Trend Drawing: It creates a trend line based on these peaks. Like the support logic, it continuously checks the data to ensure the line stays above all relevant price action, providing a clear visual of the "ceiling" where prices have struggled to break through.

Visual and Operational Features

  • Customizable Range: You can define exactly how many candles back the script should look (the start and end points of the analysis).
  • Visual Distinction: The script automatically applies different colors to differentiate between the two types of levels—typically Green for Support and Red for Resistance.
  • Real-Time Updates: The script includes a logic gate that ensures calculations are refreshed every time a new candle begins, keeping the lines current with the latest market movements.
  • Automatic Cleanup: When you remove the script from your chart, it is programmed to clean up and delete the visual objects it created, leaving your chart tidy.

Summary for the User

Essentially, this tool automates the tedious process of manually identifying where the price "bottomed out" or "peaked" over a specific period. By highlighting these levels with trend lines, it provides a clear visual map of the current market boundaries, helping traders see where price might face significant hurdles or find solid footing.
