In this lesson, we’ll focus on two key technical‐analysis patterns that signal potential trend reversals in the market: the double top and the double bottom. These formations give traders the opportunity to recognize trend changes early, which is extremely valuable when making investment decisions.
Double Bottom (“W”)
The double‐bottom formation resembles the letter “W.” It represents two unsuccessful attempts by the market to continue falling, which often leads to a strong trend reversal and rising prices.
Identification Criteria:
-
The time between the two troughs should be at least 10 days, and often spans several months.
-
The difference between the low prices of the two troughs should not exceed 3%.
-
The upward move after the first trough should exceed 10% of the lower of the two lows.
-
The confirmation price—and the confirmation line—is defined by the peak between the two troughs. A breakout above that level confirms the pattern and serves as a buy signal.
Trading Tactic:
It’s recommended to enter a long position once the confirmation line is broken to the upside, targeting further price increases. A pullback (retest) after breaking the confirmation line occurs in about 68% of cases, which can provide an additional buying opportunity.
Double Top (“M”)
The double‐top formation looks like the letter “M” and signals a potential end to an uptrend, which may be followed by a downward reversal.
Identification Criteria:
-
Price peaks at a high, then retracts, and finally retests that same high level—but fails to break through.
-
Declining volume on the second peak can further confirm the weakening of the uptrend.
-
The key element is a break below the confirmation line (the low between the two peaks), which confirms the pattern and serves as a sell signal.
Trading Tactic:
The ideal moment to sell is when price breaks below the confirmation line. A subsequent pullback (retest) after this breakdown can be used to close long positions or to open short positions.
Summary
Understanding and identifying the double‐top and double‐bottom formations can significantly enhance your trading skills by giving you an edge in anticipating market trend changes. Always remember to use additional technical‐analysis tools to confirm the signals generated by these patterns.
