Building flags, pennants, and triangles as continuation pauses

Continuation pauses, not certainties

Chart patterns are treated as recurring high-low-open-close relationships that carry a probability, not a certainty, of a similar later price movement.

Continuation or consolidation patterns are constructed as pauses inside a dominant trend after which price is expected to resume that trend. A continuation pattern is that drawn pause: it is hypothesized to resolve in the prior direction rather than reverse it. A reversal pattern instead warns that the prevailing trend may be changing direction.

Lock the parent trendline

An uptrend is constructed as sequential higher highs and higher lows with a trendline along at least two higher lows. A downtrend is sequential lower highs and lower lows with a trendline along the lower highs in at least two and preferably three places. A confirmed break of that line ends the construction.

Trend construction has no fixed clock. The same higher-high or lower-high geometry can be drawn on intraday or multi-month data, and longer constructions are treated as more reliable.

Editorial reading: lock that parent trendline before you box the pause. If the line has already taken a confirmed break, the form is no longer a pause inside a living trend construction.

Box the pause as a flag, pennant, or triangle

Flags and pennants are constructed as compact continuation pauses, grouped with wedges, that appear after a directional run. They are read as rest intervals rather than completed reversals. A flag is a compact, typically sloped rectangular pause after a directional run. A pennant is a small contracting pause after a directional run.

Descending, ascending, and symmetrical triangles are constructed as members of the continuation family. They are drawn as contracting ranges that pause, rather than reverse, the prior trend. An ascending triangle is a contracting range with a flat upper boundary and a rising lower boundary. A descending triangle is a contracting range with a flat lower boundary and a falling upper boundary. A symmetrical triangle is a contracting range of lower highs and higher lows.

Let volume accept or reject the reading

Declining volume across the life of the pause is used as construction evidence that the form is a continuation pattern rather than a finished trend change. That fade in activity is volume confirmation for the continuation reading.

If volume expands instead of contracts through a downward flag or pennant while price is falling, the construction is treated as bearish and the expected bounce at the end of the pattern may fail or last only briefly.

Volume that fails to support the drawn flag, pennant, or triangle is used as an early warning that sentiment is shifting and that the expected continuation outcome may break down. Rising activity against the expected resolution is the other side of volume confirmation: it rejects the continuation reading.

Editorial reading: contracting volume keeps the assembly standing. Expanding or unsupportive volume is how the resume-the-trend hypothesis is thrown out.
