当然，整点时刻，又有一些拉升护盘的迹象。所以汪汪队控制慢牛节奏，可能也意味着慢熊，跌起来可能也会持续阴跌为主，偶尔来一根大中阴线。值得 一提的是午后2点多跌停数量有点明显，已经有19家了，而涨停数量只有45个。说明高位股的回落还是比较明显的。跌幅超过3%的票也已经有500个了。 实际上今天我们看到微盘股跌1.1%，它是持续跌破了4条均线，30天线都破掉了，有头尖顶的结构了。 上午是上海市场是横盘震荡为主，深圳市场出现了几次跳水、几次拉升，波动幅度比较大，明天中午的时候也有一次强势拉升，结果午后开盘10分钟左右 又开启了一波跳水。现在不清楚能不能守住，因为已经在创盘中的新低了。昨天我分析市场下跌有五大理由，其中有一个要重申一下，就是国庆长假要到 了，节前通常是有缩量的，而且主力资金不愿意拉高，然后承受一周的外盘波动风险。 今天结束之后就还有7个交易日，所以未来几天基本上可以确认市场量能会逐渐的萎缩，昨天是3.14万亿，今天就只有2.4万亿了。 两点缩量已经达到6,000 亿了，在这种情况下你不要想强势拉起来很难，这种反差还是过于明显的带量下跌、缩量反抽，还不如缩量下跌呢。今晚我们看到主力资金2点出逃了600 多 ...
