基于Java語言開發旳個性化股票分析技術：能量潮指標（OBV）能量潮指標(OBV)根據股市成交量來推測股價趨勢。由美國旳投資分析家JoeGranville所創。使用措施:使用方法：1.股價上升OBV線下降，買盤無力2.股價下跌OBV線上升,買盤旺盛,反彈有望3.OBV緩慢上升,買盤漸強，買進信號4.OBV急速上升,買盤力量將盡,賣出信號5.OBV線由正轉負,下跌趨勢，賣出信號；反之,買進信號。迅動股票分析平臺在此基礎上運用Java語言開發了能量潮指標(OBV)，源代碼如下：XML描述：<?xmlversion="1.0"encoding="UTF-8"?><indicatorshortName="OBV"
