A steep flagpole, then a small, orderly channel sloping gently against the pole — one of the most recognized continuation shapes, and one of the most casually assumed to always work.
Chartists named this one for exactly what it resembled on the page — a tall flagpole with a small rectangular flag fluttering near its top.
The landmark text describes flags as typically forming roughly halfway through a move, and rates them among the more reliable continuation shapes when the flagpole is genuinely steep.
Because "flag" sounds so simple, traders now label nearly any brief pause after a move a "flag", regardless of whether the flagpole or the channel actually qualify.
Careful traders today check for a genuinely sharp, high-volume flagpole first — without one, the "flag" that follows means nothing.
Before anything else, there must be a genuinely steep, nearly vertical move on real volume — the flagpole. Without a real pole, there is no flag, no matter how tidy the channel after it looks.
After the pole, price consolidates in a tight, roughly parallel channel that gently slopes against the pole's direction — a bull flag drifts slightly down; a bear flag drifts slightly up. Volume should shrink through this part.
A confirmed flag break usually resumes the flagpole's original direction, not the flag's own slight counter-slope. Measure the pole's full height and project it again from the breakout point for a rough target.
A near-vertical run into the low $20,000s was followed by a brief, shallow, gently down-sloping channel, before the climb resumed toward $40k.
A steep sell-off in early 2022 was followed by a brief, shallow relief bounce that quietly drifted upward before the broader decline resumed — a textbook bear flag many mistook for a genuine recovery.
A sharp, high-volume rally is followed by a small, shallow channel that gently drifts down for a few sessions. Price then closes above the channel, resuming the climb. What is this?
A small, shallow, down-sloping channel forms — but it follows an ordinary, gradual grind higher, not a sharp move. A trader calls it a bull flag. Should they?
A genuine flagpole forms, but the following channel drags on for six weeks and retraces most of the pole's gain. Is this still a tradeable flag?
A pole and its brief pause, watched tick by tick on the left — and the mark it leaves in the ledger on the right. A confirmed bull flag, a confirmed bear flag — and a consolidation that never had a real pole to begin with.
A move, and a small channel after it. Judge whether a genuine flagpole actually preceded the pause — then call it: trade the resume direction, or pass (no real pole).
The classic error is calling any small, tidy consolidation a "flag" purely by its shape. The discipline is mechanical: confirm a genuinely sharp, high-volume flagpole first, and reject the pattern if the pause runs too long or retraces too deep.
A flag's fame made it the most casually invoked pattern in this course — and the shape alone was never the point. Confirm the pole, keep the pause brief and shallow, and let the resume prove itself.
A brief pause before the storm.
