分型顶底是缠论中的一个精华，说白了就是三根K线的组合形态，各种股票播放教室和直播间都有老师专题讲座。从缠论到分型，再从分型到顶底的确立和画出顶底连接的线段，是理论与实践相结合、宗教与股票相结合的经典范例。中国人的智慧，你不得不服！
【底分型】
 分型顶底分为底分型和顶分型。底分型是下跌过程中出现转折的信号，即三根K线，中间一根K线是最低的，分别包容两侧的两根K线。底分型被看为股票见底的信号，底分型出现后，相应股票则可能会打开上升通道。一只下跌中的股票，如果连底分型都没有出现，就不应当急于买入。
【顶分型】
 顶分型是上涨过程出现转折的信号，三根K线，中间一根K线是最高的，分别包容两侧的两根K线。顶分型被看为股票见顶的信号，顶分型出现后，相应股票则可能会进入下跌通道，可以考虑减仓或者清仓的卖出操作。
 分型顶底是根据分型理论编写的指标，包括分型顶底主图、分型顶底副图和分型顶底选股三个指标，非本人原创。
【使用方法】
 出现底分型信号买入，黄色线段区间持股；出现顶分型信号卖出，紫红色线段区间持币。也可以在紫红色线段转成黄色线段时买入，黄色线段转成紫红色线段时卖出。如果出现顶分型信号，但是仍然是黄色线段，没有转成紫红色线段时，可以继续持股。
【说明】
1.分型顶底指标兼顾大小波段，大波段中优势更明显，所以，更适合中长线操作。
2.公式中含有未来函数DRAWLINE，DRAWLINE是用于绘制直线段的，不会出现漂移现象，不会对底分型、顶分型信号和选股产生影响。如果你不喜欢，可以删除下面两句公式：DRAWLINE(LV1,LOW,HHV1,HIGH,0),COLORYELLOW,LINETHICK2;
 DRAWLINE(HHV1,HIGH,LV1,LOW,0),COLORMAGENTA,LINETHICK2;
