Inverted Descending Triangle Inside a Widening Wedge.
A descending triangle is an inverted version of the ascending triangle and is considered a breakdown pattern. The lower trendline should be horizontal, connecting near identical lows.
Symmetrical triangles occur when a security's price consolidates, generating two converging trend lines with opposite slopes. A symmetrical triangle's breakout or breakdown targets are equal to the distance between the initial high and low applied to the breakout or breakdown point.
