12月22日，大盘延续第三次冲顶节奏：指数在均线密集区与趋势线密集区内"边走边换手"，以相对克制 的方式向上推进。日线连续四根小阳线说明修复在延续。 一、月线：4018目标位之后，用时间消化过热 10月30日与11月14日两次触及月线目标位4018附近后，我们反复强调：牛市里到达目标位之后，常见的 不是立刻加速，而是进入日线级别的消化周期——正常55天、至少34天，用换手与震荡把过热降下来， 让趋势重新变得有序。趋势行情里最怕"情绪抢跑"，最稳的做法是等待确认点出现后再跟随。目前月线 依旧是"慢牛框架内的区间震荡"，核心任务仍是消化与换手，而不是追求直线拉升。 二、周线：洗盘周期延续，支撑有效不等于立刻反转 大盘连续三个小时在233小时均线3915与144小时均线3920之间徘徊。因为横盘之前是上涨，遇阻之后没 有撤退，而且小时级别macd和kdj保持双金叉状态，所以12月23日有望向上突破。只不过，小时级别kdj 处于高位区，意味着短线更可能用横盘或小幅回踩来消化指标，而不是持续硬拉。 这正符合《tyj均线的使用》的要点：压力位前的强势横盘，本质是"攻而未破、以换手吸收抛压"。 周线涨满89周之后的洗盘，虽 ...
