Band-Pass Filters for Isolating Market Cycles

Summary

A band-pass filter is described as a way to retain price movements within a chosen frequency range while removing slower trends and faster noise. The range it allows through is its bandwidth, which can be selected to correspond to a desired swing period.

The note suggests using changes in the filter’s color as trading signals. It gives no parameter settings, signal rules beyond color changes, chart examples, or performance evidence. The filter’s output therefore serves only as a general cycle-analysis concept here; the document does not establish that its signals are profitable or explain how to manage risk around them.

Key ideas

• A band-pass filter passes frequencies within a selected range.
• It aims to remove low-frequency trends and high-frequency noise.
• The chosen frequency range relates to the swing period being analyzed.
• The document proposes color changes as signals but gives no validation or implementation details.
