Calculating ADX and Directional Indicators with a Ring Buffer

Summary

This document describes an MQL5 class for calculating the Average Directional Movement Index (ADX) with a ring buffer. The class accepts high, low, and close price data and supports calculation across full arrays or one value at a time. Its initialization options include a smoothing period and method, buffer capacity, and an indexing mode. Accessors expose the ADX and its positive and negative directional indicator lines, along with configuration details and the number of bars required.

The examples show how to calculate the indicator from a price series and copy ADX, positive directional, and negative directional values into indicator buffers. A second example demonstrates calculations based on individual values and existing ring-buffer data. This is implementation guidance for indicator calculation and integration, not a trading strategy. It does not compare the ring-buffer output with another implementation, report speed or accuracy benchmarks, or explain how to use ADX signals to make trading decisions.

Key ideas

• The class calculates ADX and its positive and negative directional indicator lines from high, low, and close prices.
• It supports both array-based and single-value calculation methods.
• Users can configure smoothing, buffer size, and input indexing behavior.
• The examples demonstrate copying calculated ring-buffer values into indicator buffers.
• The document provides implementation instructions but no strategy rules or performance evidence.
