基于Java语言开发的个性化股票分析技术能量潮指标OBV

基于Java语言开发旳个性化股票分析技术：能量潮指标（OBV）能量潮指标(OBV)根据股市成交量来推测股价趋势。由美国旳投资分析家JoeGranville所创。使用措施:使用方法：1.股价上升OBV线下降，买盘无力2.股价下跌OBV线上升,买盘旺盛,反弹有望3.OBV缓慢上升,买盘渐强，买进信号4.OBV急速上升,买盘力量将尽,卖出信号5.OBV线由正转负,下跌趋势，卖出信号；反之,买进信号。迅动股票分析平台在此基础上运用Java语言开发了能量潮指标(OBV)，源代码如下：XML描述：<?xmlversion="1.0"encoding="UTF-8"?><indicatorshortName="OBV"
