reversal day-几个中期底部的对比

前 面跌跌不休，then big gap down at open next day, retest the open low or make new low between 12-3 pm, then rally with huge volume -------》 reversal day. 10/10/08, 1/23/08, 3/17/08, 8/16/07 all look like that. 9/18/08 alos looked like a reversal day but 9/19 quickly filled the up gap which was not a good sign. Because after a reversal day, the next day should hold up very nicely. See the hourly charts.

其他的图，只看出如果均线flat, 就no trend,带量突破consolidation, 就可吃点鱼中段， 鱼尾。下降均线，双头。上升均线，双底。加一些breakdown / breakup confirm, 似乎可以 short/long。
