FAQ
What is the typical volume profile for a Broadening Bottom?
Volume generally expands as the pattern develops, reflecting the increasing volatility and emotional intensity of the market participants.
How reliable is the Broadening Bottom according to Bulkowski?
It is quite reliable with a low break-even failure rate of 10% and an average rise of 27% in bull markets.
What is a 'partial decline' in this pattern?
A partial decline occurs when the price heads toward the lower trendline but turns up before reaching it; this is often a precursor to an upward breakout.
Why is this pattern considered difficult to trade?
The widening price swings can easily trigger stop-loss orders, making entry timing and risk management more challenging than with narrowing patterns.
