What does descending triangle mean?
A descending triangle is a bearish technical chart pattern that is formed by drawing a horizontal support line along a series of equal or nearly equal lows, and a descending line that connects a series of lower highs.
The theory is that as the lines converge the range of prices contracts, building pressure in the market.
A break below the horizontal support line is considered a sell signal and traders will often aggressively short sell and asset when that line is broken, sending prices sharply lower.
