老师，帮我修改一下 (文华财经WH8赢智V8.2)

AMAV在小于参数ER的周期内没有被赋值，修改参考：

 ERL:=10;

FASTAVGLENGTH :=2;

SLOWAVGLENGTH :=30;

CONFIRMPERIOD :=3;

STDRATIO :=1;

STDMULTIPLIER :=1;

NETCHG := ABS( C - REF(C,ERL) );

TC:=SUM(ABS(C-REF(C,1)),ERL);

ER:=IFELSE(TC>0,NETCHG/TC,0);

SR:=POW( ( ER * ( 2 / ( FASTAVGLENGTH + 1 ) - 2 / ( SLOWAVGLENGTH + 1 ) ) + 2 / ( SLOWAVGLENGTH + 1 ) ), 2 );

AMAV:=IFELSE(BARPOS<=10,C,REF(AMAV,1)+SR*(C-REF(AMAV,1)));

STDL:=SLOWAVGLENGTH;

PSTD:=STD(REF(C,1),STDL);

REF(AMAV,1)-LLV(REF(AMAV,1),CONFIRMPERIOD)>PSTD*STDRATIO*STDMULTIPLIER/100,BPK;

HHV(REF(AMAV,1),CONFIRMPERIOD)-REF(AMAV,1)>PSTD*STDRATIO*STDMULTIPLIER/100,SPK;

AUTOFILTER;
