OBV指标公式：以KDJ的写法，看上去，直观，简洁，明了。
N:=9;
TYP := (HIGH + LOW + CLOSE)/3;
RS:=SUM(IF(TYP>REF(TYP,1),TYP*VOL,0),N)/SUM(IF(TYP<=REF(TYP,1),TYP*VOL,0),N);
MFI:=100-100/(1+RS);
资金流量:MFI,NODRAW;
A1:=SUM(IF(MFI>REF(MFI,1),VOL,IF(MFI
RSV:=(A1-LLV(A1,34))/(HHV(A1,34)-LLV(A1,34))*100;
K:SMA(RSV,5,1);
D:SMA(K,3,1);
J:3*K-2*D;
