在网上找了公式：
NC:=ABS(C-REF(C,10));
TC:=SUM(ABS(C-REF(C,1)),10);
ER:IFELSE(TC>0,NC/TC,0);
SDIFF:=2/3-2/31;// www.cxh99.com
SQR:=SQRT(2/31+ER*SDIFF);
M:FLOOR((2-SQR)/SQR);
AMA:EMA(C,M);// www.cxh99.com
D:=AMA-REF(AMA,1);
FIL:K/10*STD(D,20);
TMP1:AMA-LLV(AMA,3);
TMP2:HHV(AMA,3)-AMA;
AMA-LLV(AMA,3)>FIL,BPK;
HHV(AMA,3)-AMA>FIL,SPK;
REF(ER>=9/10,1)&&ER
求高人。
