一次失敗的OE操作

9000 坐PUT車下來, January 13, 2009 Tue 在 8400 支撐位買入1200 DIA/SPY Jan CALL, expecting up to 8700-8800----8400 is a 12 weeks support line

Wed Jan 14 GAP DOWN, 8400 broken, 應該清倉持B觀望 (didn't)
Thursday continue down to 8000 then up to 8200
Friday GAP UP then down

 
教訓深刻, 準備不夠充分. 即使錯了, 依然有機會. 8000 is 黃金分割位. 此處大舉買入, 應該保證整體上不賠

實際上後來有好多次機會

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%

觀察:

1) if OE Friday 探底尾盤翻盤可能比較大, eg. 7500 那次
2) if one day before OE Thursday 探底, FRIDAY flat or high open go lower 可能比較大
