The “flagpole” is the larger preceding move. The “flag” is the subsequent consolidation. Because there is no exchange-standard definition, the minimum size, duration and slope vary across charting methods.
Measurements are method-dependent
People may measure the flagpole, consolidation width or distance to a boundary. Any projection based on those distances depends on how the pattern endpoints were selected.
Naming can bias interpretation
Directional names can encourage users to treat a pattern as a forecast. A more disciplined approach is to first describe the observable geometry and only then discuss what the chosen method claims—if anything—about outcomes.
Study the synthetic example
The Breakout Lab uses a fictional path and makes no attempt to score or validate the pattern. You can compare its geometry with triangle and rectangle examples without importing market data.
