指标使用的几点感悟：
1、股价下探支撑线（黄线）后反弹并站稳支撑线，可以在支撑线附近出现笑脸、B点或小红点提示时逢低买入，操盘线变红时加仓；
2、股价上碰压力线要注意风险，此时会两极分化，不上则下！请在操盘线变绿时考虑减仓或清仓！如果连续三天以上站在压力线之上，可以做下波段，高抛一下，在操盘线不变绿的情况下，在回踩操盘线附近时接回，一直持股到操盘线变绿；
3、生命线、二次生命线很重要，是股票运行的重要支撑价位，也可以看做是二次启动位和最低止损位，跌破这两根线的票，应该期待它跌得更彻底，一直跌到黄色支撑线才好；
4、牛熊线之下的股票受到的压力比较大，只有突破了牛熊线的票才有可能迎来美好的春天；
5、开盘竞价在“今日阻力”下方2%以内，或者高于“今日阻力”3%以内的票，当日涨的可能性大于跌的可能性；
6、人是活的，指标是死的，信心是自己给自己的，祝各位投资顺利！
