macd是所有附图指标研判趋势的基本的也是主要的指标，免费的。
最基本的操作是金叉买入，死叉卖出。
1，当diff，和macd数值金叉进入0值以上为强势区，
没有金叉但macd绿柱变为紫色时也代表股价由弱转强，
采取买入的策略。
2，当diff，macd数值进入0值下方为弱势区，
采取观望和卖出的策略。
选股最好选择月线周线和日线为macd数值都在0值以上的股票操作。
本指标有明确的顶背离和底背离提示，当然底背离就是逢低买，顶背离就是逢高卖出。

macd在0轴上金叉状态下，任何拉回都买入的机会。建议配合kdj进行互动操作。

均线参考股价在20日均线向上的票操作，配合我上传的ENE主图指标进行低买高卖操作。让你体会在股市赚钱成功的快乐！
