Chart Patterns : Triple Tops And Bottoms


Triple tops and triple bottoms are another type of reversal chart pattern in chart analysis. These are not as prevalent in charts as head and shoulders and double tops and bottoms, but they act in a similar fashion. These two chart patterns are formed when the price movement tests a level of support or resistance three times and is unable to break through; this signals a reversal of the prior trend.
Triple Top
The triple top pattern is comprised of three sharp peaks, all at the same level. A triple top occurs when prices are in an uptrend. Prices rise to a resistance level, retreat, return to the resistance level again, retreat, and finally, return to that resistance level for a third time before declining. In a classic triple top, the decline following the third peak marks the beginning of a downtrend. While the three peaks should be sharp and distinct, the lows of the pattern can appear as rounded valleys. The pattern is complete when prices decline below the lowest low in the formation. The lowest low is also called the "confirmation point."
A triple top is considered to be a variation of the head and shoulders top. Often the only thing that differentiates a triple top from a head and shoulders top is the fact that the three peaks that make up the triple top are more or less at the same level. The head and shoulders top displays a higher peak - the "head" - between the two shoulders. According to experts including Murphy, making a distinction between these two patterns is largely academic because they both imply the same thing.They are both "reversal" patterns of an upward trend in a stock. The triple top marks an uptrend in the process of becoming a downtrend.
Triple Bottom
The triple bottom pattern is composed of three sharp lows, all at about the same price level. Prices fall to a support level, rise, fall to that support level again, rise, and finally fall, returning to the support level for a third time before beginning an upward climb. In the classic triple bottom, the upward movement in the price marks the beginning of an uptrend. While the three lows should be sharp and distinct, the highs of the pattern can appear to be rounded. The pattern is complete when prices rise about the highest high in the formation. The highest high is called the "confirmation point."
A triple bottom pattern displays three distinct minor lows at approximately the same price level. The triple bottom is considered to be a variation of the head and shoulders bottom. Like that pattern, the triple bottom is a reversal pattern.The only thing which differentiates a triple bottom from a head and shoulders bottom is the lack of a "head" between the two shoulders. The triple bottom illustrates a downtrend in the process of becoming an uptrend. It is, therefore, vital to the validity of the pattern that it commence with prices moving in a downtrend.
