Inverted and descending scallops are robust performers in bull markets. Once the downward trend ends - if you can tell when that occurs - then buy and ride the new uptrend. Discovered by Thomas Bulkowski in mid 2004, but others may have found them sooner.

Inverted and Descending Scallops: Identification Guidelines

Characteristic	Discussion
Price trend	Usually downward leading to the scallop or at bearish turning points.
Shape	Looks line an inverted J.
Smooth top	Look for a rounded top, not V-shaped, but be flexible.
Down move	From the start of the pattern (point A in the above chart) to its high (B) averages 56% of the following down move from highest peak (B) to scallop end (C, the lowest valley).
Ends	Both the scallop start and end should form at price turning points.
Proportion	The height and width of the scallop should look proportional.
Confirmation	The scallop confirms as valid when price closes below the lowest valley in the pattern without first closing above the scallop's peak.

Inverted and Descending Scallops: Trading Tips

Trading Tactic	Explanation
Measure rule	Compute the height from highest peak (point B in the Measure Rule chart to the right) to lowest valley (C) then multiply it by the above 'percentage meeting price target.' Subtract the result from the lowest valley in the pattern (C) to get a price target for a downward breakout. Add the height to the top of the pattern for an upward breakout.
Short	For downward breakouts, short the stock when price closes below the lowest valley in the pattern (C in the Measure Rule figure to the right).
Cover	If price retraces (rises) 67% of the decline from B to C in the Measure Rule figure to the right, then cover the short.
Volume trend	Scallops with upward breakouts and a rising volume trend perform best.
Confirmation	Wait for confirmation before placing a trade.
Height	Tall scallops perform better than short ones.
Trend	Scallops get narrower and shorter the lower they appear in a price trend.
Throwbacks	Throwbacks hurt performance.

The Measure Rule

Inverted and Descending Scallops: Example

The above figure shows an example of an inverted and descending scallop chart pattern. Point A begins the inverted scallop pattern and price peaks at B and then trends down to C, the end of the scallop. This one forms a handle, D, and that is quite common. Price resumes the downtrend after the handle completes.
