**信号逻辑：**
1、中枢笔数必须大于等于3笔。（排除掉盘背构成的中枢）
2、中枢上沿做空，中枢下沿做多（不区分中枢方向）
以开空仓为例（中枢上沿），当向上一笔出现次级别分型停顿后，定义次级别收盘价为 P，次级别顶分型高点为 H ，则需满足：
1. H>=本级别中枢上沿价格
2.（H-本级别中枢上沿价格）< 本级别中枢高度
3.（H-P）*3 < 中枢高度
4. 本级别MACD黄白线死叉确立（已经走出并列向下走势）
稍微解释一下几个条件的内在逻辑：
1. H>=本级别中枢上沿价格 ： 确保是在中枢的上沿
2.（H-本级别中枢上沿价格）< 本级别中枢高度 ： 确保中枢上沿不要太远的距离，太远了可能下跌就形成三买上去了。这种点不要。
3. （H-P）*3 < 中枢高度 ： H-P，其实就是一个次级别分型停顿的高度了，这里就是为了排除掉奔走型中枢，区间特别小的中枢，没必要做。
