Calculating ATR with Wilder Smoothing in MQL5

Summary

The document introduces an MQL5 implementation of Average True Range that calculates the indicator without calling the platform’s built-in ATR function. It explains ATR as a volatility measure derived from true range values and describes Wilder smoothing as a way to smooth changes in the resulting series.

The post presents the code as a practical implementation, but the supplied text does not include the code body, calculation steps, comparison against the built-in indicator, or test results. It also makes a historical distinction between the original ATR and later use of Wilder smoothing, without detailing that distinction. The implementation’s accuracy and behavior therefore cannot be assessed from the document alone; it is most useful as an introduction to the indicator’s purpose and smoothing concept.

Key ideas

• ATR uses true range to describe price volatility.
• Wilder smoothing reduces fluctuations in the ATR series.
• The post presents an implementation that avoids the built-in MQL5 ATR function.
• No implementation details, validation results, or trading rules are provided in the text.
