Bollinger Band Breakouts as Trend or Reversal Signals

Summary

The document describes a basic signal based on a closing price moving beyond the upper or lower Bollinger Band. Such a breach can be interpreted in two different ways: as evidence of a reversal or as the start of a trend. The proposed use is to display arrows at signal points.

The suggested band deviation may differ by interpretation: use a somewhat larger deviation for reversal signals than for identifying a trend start. No precise deviation settings, entry or exit rules, risk controls, market context, or empirical results are provided. The description therefore presents a simple indicator concept rather than a tested strategy; a band breach alone does not establish which interpretation is appropriate.

Key ideas

• A close above the upper band or below the lower band is treated as a potential signal.
• Traders may interpret band breaches as either reversals or trend starts.
• The suggested deviation is slightly higher for reversal use than for trend-start use.
• Arrows can mark signals, but the document supplies no performance evidence or complete trading plan.
