//★买入必看：若MA20为下降趋势：随时准备撤退。顶背离：慎重抄底。震荡市看MA20，牛市抄底看MA20、30和60。 //★有明显向上趋势时，若macd降至3或-3以下，但无背离产生或者已经接近20日线，可暂不执行卖出操作。
//★周线：短期内macd二次金叉买进；在50上方运行较长时间后，向下调整至50附近，参与抄底抢反弹，尤其是第一次。
//MACD：MACD<3，macd线或面积背离则清仓；未发生顶背离，在趋势线上方且距离趋势线较近，可观望，若最低点距离趋势线较远，待调整到趋势线附近进入。
//M顶：MACD柱M头,距离趋势线太远，有回调需求。
//短3：短线抄底，持有不超过3天，除非与趋势衔接上。
//二次金叉：macd二次金叉，买入信号，成功率较高，尤其是在0轴附近，但必须注意止损,当在趋势线受阻或macd柱缩短时，清仓。
