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
