81.问:
编写个OBV与股价在N个交易周期后行成背离走势的选股公式吗?最好是能排序指标. 分析家软件 答(馨芸): 仔细观察许多股票,发现OBV与股价背离后的走势关系不明显,这样的选股效果不佳, 且我不熟分析家,建议你试试参考常用的macd,rsi,及kdj背离A1:=BARSLAST(ref(cross(“macd.diff”,“macd.dea”),1));B1:=ref(c,A1+1)>c and ref(“macd.diff”,A1+1)<“macd.diff” and cross (“macd.diff”,“macd.dea”);DRAWTEXT(FILTER(B1>0,5),0,‘MACD’),COLORGREEN,ALIGN0;;Stickline(FILTER(B1>0,5),-1,0,1,0),COLORGREEN;A2:=BARSLAST(ref(cross(“kdj.k”,“kdj.d”),1));B2:=ref(c,A2+1)>c and ref(“kdj.k”,A2+1)<“kdj.k” and cross(“kdj.k”,“kdj.d”);DRAWTEXT(FILTER(B2>0,5),0.5,‘KDJ’),COLORYELLOW,ALIGN0;;Stickline(FILTER(B2>0,5),0.5,-1,1,0),COLORYELLOW;A3:=BARSLAST(ref(cross(“RSI.RSI1”,“RSI.RSI2”),1));B3:=ref(c,A3+1)>c and ref(“RSI.RSI1”,A3+1)<“RSI.RSI1” and cross (“RSI.RSI1”,“RSI.RSI2”);DRAWTEXT(FILTER(B3>0,5),-0.25,‘RSI’),COLORCYAN,ALIGN0;;Stickline(FILTER(B3>0,5),-1,-0.25,1,0),COLORCYAN;(FILTER(B1>0,5) or FILTER(B2>0,5) or FILTER(B3>0,5) )*3; QUOTE:82.问: 5日均线死叉10 日均线后在13天内金叉10日均线，5、10两均线在30日均线之上，且30日均线上行 答(骑兵):sumbars(cross(ma(c,10),ma(c,5)),1)<13 and ma(c,10)>ma(c,30) and ma(c,5)>ma(c,30) and cross(ma(c,5),ma(c,10)) and ma(c,30)>ref(ma(c,30),1);
