原理解析：
P赋值:5
如果CAPITAL=0返回成交额/100000000否则返回成交量
VA赋值:IF(收盘价>1日前的收盘价,VP,-VP)
输出OBV:SUM(IF(收盘价=1日前的收盘价,0,VA),0), 线宽为2
输出M12:OBV的12日指数移动平均
输出M50:OBV的50日指数移动平均, 线宽为2,COLOR00FF00
A1赋值:P日前的OBV=2*P+1日内OBV最高值
B1赋值:A1的P过滤
C1赋值:BACKSET(B1,P+1)
D1赋值:C1的P过滤
A2赋值:P日前的OBV=2*P+1日内OBV最低值
B2赋值:A2的P过滤
C2赋值:BACKSET(B2,P+1)
D2赋值:C2的P过滤
输出上:REF(OBV,上次D1距今天数),COLORFF00FF,NODRAW
输出下:REF(OBV,上次D2距今天数),COLOR00FF00,NODRAW
向输出上:OBV上穿上*1.01,NODRAW
输出相对能量:(OBV-下)/(上-下)*100,画黄色,NODRAW
R11赋值:BACKSET(ISLASTBAR,上次D1距今天数+1)
S11赋值:R11>1日前的R11
DRAWLINE(D1,OBV,S11,OBV,1),画黄色
T11赋值:BACKSET(ISLASTBAR,上次D2距今天数+1)
U11赋值:T11>1日前的T11
DRAWLINE(D2,OBV,U11,OBV,1),COLOR00FF00
当满足条件C>0时,在下和下之间画柱状线
当满足条件C>0时,在上和上之间画柱状线
DRAWTEXT(OBV上穿上*1.01,上,'上'),画黄色
DRAWTEXT(下*0.99上穿OBV,下,'下'),画黄色
当满足条件D1时,在OBV和1之间画图标
当满足条件D2时,在OBV和2之间画图标
如果M12>M50返回M12否则返回DRAWNULL
IF(M50>1日前的M50,M50,DRAWNULL),画红色, 线宽为2
