一次失败的OE操作

9000 坐PUT车下来, January 13, 2009 Tue 在 8400 支撑位买入1200 DIA/SPY Jan CALL, expecting up to 8700-8800----8400 is a 12 weeks support line

Wed Jan 14 GAP DOWN, 8400 broken, 应该清仓持B观望 (didn't)
Thursday continue down to 8000 then up to 8200
Friday GAP UP then down

 
教训深刻, 准备不够充分. 即使错了, 依然有机会. 8000 is 黄金分割位. 此处大举买入, 应该保证整体上不赔

实际上后来有好多次机会

For example
Jan 82 CALL
once $0.22 (Thursday) to $1.6 Friday at Open 700%
once $0.22 to $1.1 Friday during the day 500%

观察:

1) if OE Friday 探底尾盘翻盘可能比较大, eg. 7500 那次
2) if one day before OE Thursday 探底, FRIDAY flat or high open go lower 可能比较大
