飞狐JA1-ASI源码公式：
LC:=REF(CLOSE,1);
AA:=ABS(HIGH-LC);
BB:=ABS(LOW-LC);
CC:=ABS(HIGH-REF(LOW,1));
DD:=ABS(LC-REF(OPEN,1));
R:=IF(AA>BB AND AA>CC,AA+BB/2+DD/4,IF(BB>CC AND BB>AA,BB+AA/2+DD/4,CC+DD/4));
X:=(CLOSE-LC+(CLOSE-OPEN)/2+LC-REF(OPEN,1));
SI:=16*X/R*MAX(AA,BB);
ASI:SUM(SI,0);
高:HHV(ASI,14);
低:LLV(ASI,14); |
