Price Patterns


Triangles


A triangle occurs as the range between peaks and troughs narrows.  Triangles typically occur as prices encounter a support or resistance level which constricts the prices.

A "symmetrical triangle" occurs when prices are making both lower-highs and higher-lows.

An "ascending triangle" occurs when there are higher-lows (as with a symmetrical triangle), but the highs are occurring at the same price level due to resistance.  The odds favor an upside breakout from an ascending triangle.

A "descending triangle" occurs when there are lower-highs (as with a symmetrical triangle), but the lows are occurring at the same price level due to support.  The odds favor a downside breakout from a descending triangle.
Just as pressure increases when water is forced through a narrow opening, the "pressure" of prices increases as the triangle pattern forms.  Prices will usually breakout rapidly from a triangle.  Breakouts are confirmed when they are accompanied by an increase in volume.

The most reliable breakouts occur somewhere between half and three-quarters of the distance between the beginning and end (apex) of the triangle.  There are seldom many clues as to the direction prices will break out of a symmetrical triangle.  If prices move all the way through the triangle to the apex, a breakout is unlikely.
