KDJ超准买入公式

用它判断底部九生一死！

UPPERL:= MA(HIGH,30)*(1+15/100);
 UPPERS:= MA(HIGH,3)*(1+3/100);
 LOWERS:= MA(LOW,3)*(1-3/100);
 LOWERL:= MA(LOW,30)*(1-15/100);
买点:EMA(IF(L<= LLV(L,30),SMA(ABS(L-REF(L,1)),30,1)/SMA(MAX(L-REF(L,1),0),30,1),0),3)*10,STICK,COLORRED,LINETHICK2;
 AA:=IF(UPPERS>UPPERL,90,100);
卖点:IF(AA=90,100,0),STICK,LINETHICK3,COLORGREEN;{COLORFF7700}
