编写条件：
BIAS(6,12,24）6日乖离率超过－6%，12日乖离率超过－10%，24日乖离率超过－16%。。画条直线编写方法：
bias1 :=(CLOSE-MA(CLOSE,6))/MA(CLOSE,6)*100;
BIAS2 :=(CLOSE-MA(CLOSE,12))/MA(CLOSE,12)*100;
BIAS3 :=(CLOSE-MA(CLOSE,24))/MA(CLOSE,24)*100;
TT:=BIAS1>-6 AND BIAS2>-10 AND BIAS3>-16;
DRAWLINE(TT,L,REF(TT,1),REF(L,1),1),LINETHICK2,COLORRED;
