Flags that lean the wrong way

Flags are brief pauses after a sharp move. In classical chart pattern recognition, the flag cloth usually slopes gently against the preceding impulse: a bull flag drifts down or sideways after a rise; a bear flag drifts up or sideways after a fall.

The common classroom error

Students see a tidy channel and reach for the flag label even when the channel continues in the same direction as the impulse. That shape may still be tradeable under some methods, but it is not the classical flag we teach. Names matter because they carry expectations about break direction and measured moves.

Duration and proportion

A flag that lasts longer than the prior impulse begins to look like a new trend segment rather than a rest. We compare bar counts and vertical distance before committing to the label. Pennants receive the same scepticism: tight coils are fine; sprawling triangles wearing a pennant costume are not.

Practice without pressure

In the Evening Pattern Circle we pass charts that include deliberate near-misses — almost-flags that fail the slope test. Naming the failure out loud is part of the craft.
