 | |  | | 与下降楔型不同,下降楔形翻转形态增加了一个先期下跌阶段的要求。
这样,下降楔形翻转形态,常常概括了整个修正阶段。
而下降楔形仅仅作为修正阶段的一部分成立,通常为浪 A 阶段。
由此,随着下降楔形的成立,后市通常引导一波反弹走势;
然而,随着下降楔形翻转形态的成立,后市常常引导一波新的涨势。
这里提供一个实战范例 —— 美元/日元。
在前期自108。90附近启动的下跌修正过程中,产生了一个几乎完美的下降楔型翻转形态。

下降楔形,经常在各个时间框架内出现,频率非常高。然而,经典的,规范的下降楔形翻转形态的例子不是很多,常常与类似的三角形形态混淆。
注意几个要点:
早期的上行趋势,是必需条件,
先期的下降运行阶段,(和后期形态发展,理想的运行时间比例,1:1-2)
由价格反应形成的低点和高点,组成的支撑线和压制线,收拢。
英文原文:
Prior Trend: To qualify as a reversal pattern, there must be a prior trend to reverse. Ideally, the falling wedge will form after an extended downtrend and mark the final low.
Upper Resistance Line: It takes at least two reaction highs to form the upper resistance line, ideally three. Each reaction high should be lower than the previous highs.
Lower Support Line: At least two reaction lows are required to form the lower support line. Each reaction low should be lower than the previous lows.
Resistance Break: Bullish confirmation of the pattern does not come until the resistance line is broken in convincing fashion. It is sometimes prudent to wait for a break above the previous reaction high for further confirmation. Once resistance is broken, there can sometimes be a correction to test the newfound support level.
Volume: While volume is not particularly important on rising wedges, it is an essential ingredient to confirm a falling wedge breakout. Without an expansion of volume, the breakout will lack conviction and be vulnerable to failure.
