SPY 02/05/2010 Bottom?


6.4.A SPY Bottom Shape,看一下最牛时期底部的形状,V shape bottom is rare because technically nobody can stand on just one leg.



6.4.1 Extreme NYADV Readings Watch,vertical dashed lines,NYADV下跌动能很大的时候,一般不会第一次反弹就成功的。



6.3.1 Major Accumulation Day Watch,注意下面的NYMONYMO的positive divergence是bottom的重要标志。




6.3.2c Major Distribution Day Watch,介个周四的报告里说了,NYDNV:NYUPV > 35,意味着very close to a bottom。顺便说,从图上看,根据一个hammer就喊底,似乎并不可靠。



应该以SPY为准,经back test验证,比较可靠的底部条件有三,周五符合了两个:

  1. Volume is at least 2 times larger than its 100 day moving averages. (Check)
  2. The day’s trading range > ATR(10) x 1.1. (Check)
  3. Open below BBbottom. (Sorry, no, actually, it’s a gap up open last Friday)

然条件3可能不是那么重要,尤其是周五的Hammer,有60%的机会leading to a bullish reversal, 因此俺不能据此否定周五是bottom的可能性.
