A Lightweight Three-Pole Butterworth Moving Average Filter

Article MQL5 code base

Summary

This short description introduces a three-pole Butterworth filter used to smooth price or another selected input series. It characterizes the indicator as providing smoothing while using modest processing resources, making it a potential alternative for charts or trading applications where computation matters.

The indicator supports selecting the price type and placing it over earlier indicators. Its smoothing ratios come from another version of the original filter. The text names the underlying author and points to related implementations, but does not explain the filter equations, parameter choices, frequency response, lag, or behavior in different market conditions. It also offers no charts, benchmark, or backtest results. Readers therefore get a basic description of the tool’s purpose and options, but not enough information to judge its smoothing trade-offs or whether it improves a trading method.

Key ideas

  • The indicator applies a three-pole Butterworth filter to smooth a selected input series.
  • It is described as providing smoothing with modest CPU use.
  • Users can choose a price type and overlay the filter on earlier indicators.
  • The description gives no quantitative evidence about lag, filtering quality, or trading performance.
