MACD指标的构造起点是股价的平滑移动平均线EMA，所以，决定了它的强势性与稳定性的特点，同时它克服了均线频繁发出假性信号的缺陷，使得它对中长期趋势的把握准确率较大，深受趋势买家的喜爱。既然它有无可挑剔的稳定性，那么，它的滞后性也随之而来。因此，对这个问题的解决方法只有仰仗指标参数的优化来搞定了。
MACD指标一般不适合短线和超短线的股友使用，也不适合在盘整行情下使用。通常来说，在短线和超短线交易中需要你对股价的短期波动灰常敏感。而MACD指标的滞后性对股价短期波动太难及时地给予反映，因此，MACD指标就十分不适合短线客操作了。此外，在盘整行情中，它一般会围绕0轴上下运动，频繁发出金死叉等交易信号，而，这些信号往往大多数均属无效信号。
