This is reflected in the trading volume with a decreasing trading volume followed by a sharp rise as the breakout occurs.
The
opposite is true for the bullish pennant. In this case, resistance is decreasing while support remains constant. Market
volume mirrors that of a bearish pennant with a sharp rise in traffic as the breakout occurs.
If you plan on trading in this
security, your trade indicator is when price breaks through the support or resistance lines. Buy or sell as appropriate.
