Bollinger Band Stops Using EMA Deviation

Article MQL5 code base
Read the original

Summary

This indicator modifies a Bollinger Band Stops calculation by using deviation from an exponential moving average in place of the standard deviation used in typical versions. The document presents the change as a variation on the established stop indicator, without detailing the precise formula, parameter settings, or how the resulting levels should be used in a trading system.

The note recommends experimenting with the parameters before applying the indicator to live trading. It provides no comparisons against standard-deviation-based stops, chart examples, backtests, or evidence of improved performance. As a result, the method is best understood as an indicator variation whose behavior and usefulness depend on implementation choices and validation across relevant markets and conditions.

Key ideas

  • The indicator adapts Bollinger Band Stops by using EMA deviation instead of standard deviation.
  • The document does not specify the full calculation or recommended parameter values.
  • Parameter experimentation is advised before live use.
  • No comparative results or backtest evidence are given.
