High Tight Flag
Also called: HTF
A rare, powerful continuation pattern: a near-vertical 100%+ advance, then a shallow, tight flag that often launches another sharp leg up.
Popularized by William O'Neil, the high tight flag forms when a stock roughly doubles in four to eight weeks (the flagpole), then drifts sideways-to-down no more than about 10–25% over a few weeks (the flag). A shallow pullback after an explosive move signals holders refuse to sell — extreme demand.
The buy point is a breakout above the flag on strong volume. It's one of the most bullish, and rarest, patterns; the same violent prior move that makes it powerful also makes it volatile and prone to failure, so risk control matters.
On StockSetups
StockSetups does not flag high tight flags: they had the weakest forward record of any pattern we tracked. The board's bull flags and pennants cover the same continuation idea, and the relative-strength rating and tight-range flags (NR7, tight closes) help judge a strong prior move.
