Reverse Symmetrical Triangle (Megaphone Chart Pattern)
A Megaphone Top also known as a Broadening Top is considered a bearish signal, indicating that the current uptrend may reverse to form a new downtrend.
A Megaphone Top is a relatively rare formation. Its shape is opposite to that of a Symmetrical Triangle. The pattern develops after a strong advance in a stock price and can last several weeks or even a few months.
A Megaphone Top is formed because the stock makes a series of higher highs and lower lows. The Megaphone Top usually consists of three ascending peaks and two descending troughs. The signal that the pattern is complete occurs when prices fall below the lower low.
