NIO. Expansionary wedges

An expansionary wedge, more commonly known as a broadening wedge, is a technical chart pattern that indicates increasing market volatility and uncertainty. Unlike traditional wedges where trendlines converge, a broadening wedge is formed by two diverging trendlines that spread outward, forming a megaphone shape.
Broadening wedges can signal potential trend reversals or continuations, depending on the pattern's direction and context. However, they are known to be tricky and prone to false breakouts, so traders must use a careful strategy with other confirmation indicators.
