**如何分辨是bullish 还是bearish Butterfly pattern 的呢? **
Gartley跟蝴蝶很相似，都是W型或者 M型的趋势线
看x点的开始，是在高点还是低点。高点就是熊市，低点就是牛市
Bearish Butterfly ====> 趋势 X点到另低A点会回调， 要在0.618-0.786之间，回调不能超过0.786，为B点
A点到B点，C点不可以低过A点，要在fibo 0.383
D点是由X点到A点衍生，1.27点位(Fibo extension)将是其位置，但是不可以和x点同位，或超过其价格
或者，D点是由A点到B点衍生，1.68- 2.168点位(Fibo extension)将是其位置
x点在高位的话将会是个熊市
SL是X点位的20pips之后，TP1:在0.382， TP2:在0.618

closing a portion of your position prior to this level as price approaches key swing points within the structure.
These important levels include the price swings at points B, C, and A.
If a breakout through the A level occurs, then you can be fairly confident that the projected target at the 161.8% extension of the CD leg should be achieved.
BC: The BC move should take either the 38.2% or 88.6% retracement of the AB move.
BC的点位 either是 0.382 或者是0。886 回调 of AB
**CD: If BC is 38.2% of AB, then CD is likely to reach the 161.8% extension of BC. On the other hand, if BC is 88.6% of AB, then CD is likely to reach the 261.8% extension of BC.
如果bc是0.382，那么cd 很可能去到1.618 of bc.
如果bc是0.886，那么cd 很有可能去到2.618 of bc**
