什么叫好用？适合自己的，在股市中能挣钱的指标，就是好用的指标。
均线好用吗？其实很好用。均线是分大小，分级别。许多人只是看多头排列，空头排列，金叉，死叉，支撑，压力等。说实在的，会这些只能是小学水评。
而真正理解均线，必须要知道均线的由来。许多人可能会认为：知道怎么来的。如30日均线就是由30个交易日的收盘价（或点）相加除以30而得来的平均值。没错。但明天呢？后天哪？再远一点哪？不还沒有收盘价（点），怎么能出来。有聪明人会用推演去画出来。这是可以的，但要是学会扣减。则对于任何均线后期如何走是有很方便的预判，这就是要理解均线的内在含义。
而均线又可以配合乖离率，压力区，能正确预判出来顶部区域而抛出获利股票。
我只是简单举例说说均线而已。电脑中这么多指标，有三～五指标用好，用精。挣钱只是挣多，挣少的事了。
技术不是万能的，没有技术是万万不能的。
本人通过多个指标的配合。比较准确的在顶部区域成功的抛出股票。若有幸观注本人的。在大盘顶部区域本人会有告知的。
操作成功案例：中国平安601318抛出区域。83元--91元。19年至2020年春节前（只留下100股底仓，47元成本）。华侨城在今年，10.2元抛出（顶部区域）。
注：我说的是顶部区域，而不是某个高点或是最高点。我还真不能准确判断最高点的位置，也沒有这个本事。但卖在顶部区域还是可以的。
1、股市中，指标到底有没有用？
编过300多个指标，告诉你，没用，都是事后诸葛亮！股市盈利靠的是策略和纪律！
指标到底有没有，仁者见仁智者见智，每个人接触指标的时间不同，使用的指标不一样，可能效果就 不一样，我给你分享一款自己使用的，挺好用的成功率90%以上的指标，希望对你炒股有所帮助

有用，关键看你是怎么用，用什么指标！不是所有指标都适合散户，就比如KDJ这个指标，太快了，不适合散户！还有什么布林线上轨，下轨太迟缓了，刚炒股的小散户更看不懂，所以这些指标更没用！我现在只用四个指标，一个就是DKX，二就是TRIX，三就是MACD，还有一个不能说，这个是跟踪大牛股的指标，不是我故弄玄虚，我也是受一高人指点后才醒悟的，所有大牛股的产生都必须出现这个指标！但初入股市的散户只需要把上面的三个指标看懂了，你也就不会亏！
