如何判断一个指标是否是好指标？
指标的意义在于提示主力的异动。那么怎么才有利于我们更快更容易把握住主力脉搏呢？我们应该力求指标及时的、准确的、明确的、简洁的、直观的将主力的异动汇报给我们。
及时、准确是指标的生命线，不准确或不及时的信号都会贻误战机，这是指标的内在要求。
但是指标作为一种图形化的信息，达到人的大脑需要经过视觉系统的转化，为了更快捷的进行信息转化，势必要求指标所呈现的图形简明扼要，能让人直观的把握要领，否则，让人看得晕头转向，同样会降低决策效率和反应速度。因此，这是指标的外在要求。
综合上述，好的指标应该是及时、准确、简明、直观的。这是我们判断指标好坏的终极标准！
我见过很多指标，要么失之过简（简单的简），要么失之过繁 ，一个没有深度，一个眼花缭乱，都不能很好的为操盘服务。我个人觉得，公式的编写应尽量将繁杂的信息简化，这种简化主要体现在优化画面和整合买卖信号上，即使是复合式的指标公式，也尽量以简明的色带、图标呈现出来，尽量减少不必要的杂乱的线条，虽然信息量较大，但是依然清爽。
以上就是我作为一个基本面为前提下的技术分析派的一点心得，希望能引起同道的共鸣。
