Smoothing Standard Deviation with a Three-Period Moving Average

Article MQL5 code base
Read the original

Summary

The document introduces a smoothed version of the standard deviation indicator and states that its smoothing period is three, using a moving-average routine. It distinguishes this measure from conventional standard deviation and refers to an image comparing the two, but the image and any numerical observations are not included in the text provided.

The note offers a basic indicator concept rather than a trading strategy: smoothing can make a variability measure appear less jagged, while potentially reducing its responsiveness to abrupt changes. It does not specify the standard-deviation lookback, the exact smoothing calculation, the price series used, or how a trader might interpret the indicator in entries, exits, or risk controls. No backtest, performance evidence, or market-specific guidance is supplied, so the document supports only a limited understanding of the indicator setup.

Key ideas

  • The indicator applies smoothing to conventional standard deviation.
  • The stated smoothing period is three.
  • The calculation uses a moving-average routine.
  • The document mentions a visual comparison but supplies no observations from it.
  • It does not define a trading rule or report performance evidence.
