A Framework for Classifying Chart Pattern Breakouts
Extending Peter Brandt's Last Full Day Low Rule: A Framework for Classifying Chart Pattern Breakouts
Introduction
Peter Brandt is widely recognized for his disciplined approach to classical chart pattern trading. While much attention is given to identifying chart patterns and measuring price objectives, Brandt places equal importance on trade management and risk control. One of the cornerstones of his methodology is the Last Full Day (LFD) Low Rule, which provides an objective reference point for managing risk immediately after a breakout.
Beyond its application as a protective stop, the Last Full Day Low can also serve as an effective tool for evaluating the quality of a breakout. By observing how price behaves relative to this level after a breakout, chart patterns can be classified into four distinct categories ranging from high-momentum breakouts to complete failures.
This article combines Brandt's original concept with a systematic breakout classification framework.
