This lesson explores how price is commonly discussed as behaving in relation to the upper and lower bands, directly setting up this unit's final lesson on limitations during strong trends.

This is general educational content, including a direct clarification from the indicator's original developer regarding a common misconception.

01SECTION 01

Price Touching or Approaching a Band

Price approaching or touching the upper band is sometimes discussed in relation to relatively elevated conditions (conceptually similar to the overbought discussions covered in the RSI and KDJ units), while price approaching or touching the lower band is sometimes discussed in relation to relatively depressed conditions (conceptually similar to oversold).

02SECTION 02

A Direct Clarification from Bollinger Himself

John Bollinger, the indicator's developer, has specifically clarified that a touch of either band is not, by itself, a signal to buy or sell — he has described such touches as "tags" rather than signals. This direct clarification from the indicator's own creator is an important, specific piece of context for interpreting price interaction with the bands appropriately.

03SECTION 03

Bouncing Within the Bands in Range-Bound Conditions

In range-bound markets (covered in the Market Guides module), price is sometimes discussed as tending to bounce between the upper and lower bands, reverting back toward the middle band after touching either extreme — a pattern sometimes referred to as mean reversion.

04SECTION 04

Why This Behaviour Differs in Trending Conditions

This bouncing behaviour is generally discussed as being more relevant to range-bound conditions specifically. In strongly trending conditions, price can behave quite differently in relation to the bands, a distinction explored in full detail in this unit's final lesson.

Summary

Price touching the upper or lower Bollinger Band is sometimes discussed in relation to relatively elevated or depressed conditions, though John Bollinger himself has specifically clarified that such touches are 'tags,' not standalone buy or sell signals. In range-bound markets, price is sometimes discussed as bouncing between the bands and reverting toward the middle band, though this behaviour is generally discussed as differing during strongly trending conditions, explored in the next lesson.

Frequently Asked Questions

Relatively elevated conditions, conceptually similar to the overbought discussions covered in the RSI and KDJ units.
