Using the Phase Change Index to Identify Market Regime Shifts

Summary

The document introduces the Phase Change Index (PCI) as a technical indicator intended to identify transitions among consolidation, rising-price, and falling-price phases. It first frames these states in terms of whether prices remain relatively stable, move higher, or move lower, then presents PCI as a tool for detecting changes between them.

The indicator is attributed to an article by M. H. Pee in TASC, but the document does not include the calculation formula, parameter choices, chart examples, or performance tests. It notes a deviation in the implementation: following the referenced formula literally appears to invert the displayed trend relative to actual market direction. An option is therefore offered to show inverted values, which the author considers more intuitive. Readers would need the referenced source or an implementation with fuller documentation to evaluate the signal and its behavior across markets.

Key ideas

• The Phase Change Index is intended to identify transitions in market phases.\nThe phases described are consolidation, uptrend, and downtrend.\nThe implementation reportedly reverses the trend direction when it follows the cited formula literally.\nAn option to invert displayed values is provided.\nThe document gives no formula details or evidence about trading performance.
