What Does a Cup and Handle Pattern Tell You?
American technician William J. O'Neil defined the cup and handle (C&H) pattern in his 1988 classic, How to Make Money in Stocks, adding technical requirements through a series of articles published in Investor’s Business Daily, which he founded in 1984.

O'Neil included time frame measurements for each component, as well as a detailed description of the rounded lows that give the pattern its unique teacup appearance.

As a stock forming this pattern tests old highs, it is likely to incur selling pressure from investors who previously bought at those levels; selling pressure is likely to make price consolidate with a tendency toward a downtrend trend for a period of four days to four weeks, before advancing higher. A cup and handle is considered a bullish continuation pattern and is used to identify buying opportunities.
It is worth considering the following when detecting cup and handle patterns:

Length: Generally, cups with longer and more "U" shaped bottoms provide a stronger signal. Avoid cups with sharp "V" bottoms.
Depth: Ideally, the cup should not be overly deep. Avoid handles that are overly deep also, as handles should form in the top half of the cup pattern.
Volume: Volume should decrease as prices decline and remain lower than average in the base of the bowl; it should then increase when the stock begins to make its move higher, back up to test the previous high.
