Pivot Point是日内交易方法，非常简单实用，是一套非常“单纯”的阻力支持体系，
大概是10年前一个做期货的高手发明的方法，至今已经广泛的用在股票、期货、国债、
指数等高成交量的商品上。经典的Pivot Point是7点系统，就是7个价格组成的，目前
广泛使用的13点系统，其实都是一样的，不过是多加了6个价格罢了，用于大成交量的
商品。下面的就是公式：
pivot:= (high + low + close) / 3;（前一天的最高、最低和收盘）
r1:= 2*pivot - low;s1:= 2*pivot - high;r2:= pivot + (r1-s1);
s2:= pivot - (r1-s1);
r3:= high - (2 * (low - pivot));
s3:= low - (2 * (high - piv |

latiner (槟榔) 于 (Tue Aug 23 01:02:58 2005) 提到:
跳了这么久的舞，从来都没这么郁闷过。
套路是这样的： Natural spin turn (overturned) -> double pivots -> backlock t
o the right -> chassee
我主要的问题有两个，其实都是和pivots有关的。
1。 natural spin turn 在3&的时候男士落在女士外侧（女士右侧），然后pivot， 完
成旋转。 我总是转不到位，也就是总是3落在女士前方，不是侧面，没法完成pivot。
2。 double pivots也是差不多的问题。 就是1& 的时候总是左脚落不到女士右侧，没法
继续。
也不是知道稀里糊涂的说明白了没有。谁给指点指点。
现在每次一到Natural Spin我就搞得耗紧张，郁闷。。。

A Pivot Point is a price level of significance in technical analysis of a
