主力扫描仪说明

指标采用颜色来区分，红、黄和、紫代表着强势，绿色和蓝色代表弱势，柱线长短代表强／弱的程度。
　　上边绿色与粉红色，是该股与大盘比较的结果。绿色渐短或粉色渐长表示与大盘比较在走强，反之则走弱。利用此参数，
可以找到市场热点。
　　红、兰色柱线，是价格趋势，兰色渐短或红色渐长表示其趋势向好，反之向坏。兰色触顶超卖，有反弹要求，只要不是未开跌停板或者连续无量跌停，就是抢反弹的好机会。红色触顶超买，有回调压力。黄、绿指标，描述的是主动买进还是主动卖出，黄色渐长或绿色渐短，主动买进者多，能量积累，绿色渐长或黄色渐短，主动卖出者多，能量释放。绿色触顶，不一定反弹，黄色触顶不一定回调。
以上指标整合了技术分析的价格、成交量和市场的热点等要素。相辅相成，一定要配合使用。

买点一：蓝色刻度线触顶，抢反弹。选股时，使用“兰柱线>145”来选。到顶是150。

买点二：红色柱线连续两天在强弱线以上时，短线赚钱的概率相当大，若能考虑大盘，则成功率更高。选股时，使用“红柱线>50”来选。

买点三：红黄柱渐长，粉色出现，上涨趋势成立，买进。

买点四：粉色、红黄柱长期向好，长期红色，可以抓到大牛股。

买点五：红柱在强弱线之上，股价收阴，红柱收长，背离。绝好的短线买点，杀进。使用买点二的办法选，人工判断。

在确定买入时，如果配合乖离线，效果更佳。
