I always prefer the much maligned reverse cow-girl
"A double top occurs when prices form two distinct peaks on a chart. A double top is only complete, however, when prices decline below the lowest low - the "valley floor" - of the pattern. The double top is a reversal pattern of an upward trend in a stock's price. The double top marks an uptrend in the process of becoming a downtrend.
Sometimes called an "M" formation because of the pattern it creates on the chart, the double top is one of the most frequently seen and common of the patterns. Because they seem to be so easy to identify, the double top should be approached with caution by the investor.
According to Schabacker, the double top is a "much misunderstood formation." Many investors assume that, because the double top is such a common pattern, it is consistently reliable. This is not the case. Schabacker estimates that probably not more than a third of them signal reversal and that most patterns which an investor might call a double top are not in fact that formation.2 Bulkowski estimates the double top has a failure rate of 65%. If an investor waits for the breakout, however, the failure rate declines to 17%.
The double top is a pattern, therefore, that requires close study for correct identification."
