当股价到达中轨时预警
源码如下：
AA:=MA((2*CLOSE+HIGH+LOW)/4,5);
通1:=AA*102/100;
通2:=AA*(200-102)/100;
CC:=ABS((2*CLOSE+HIGH+LOW)/4-MA(CLOSE,20))/MA(CLOSE,20);
DD:=DMA(CLOSE,CC);
上:(1+7/100)*DD,CIRCLEDOT,COLOR0099FF;
下:(1-7/100)*DD,CIRCLEDOT,COLOR0099FF;
中:(上+下)/2,CIRCLEDOT,COLOR0099FF;
中下:(中+下)/2,colorf0f000;
解答如下：
CC:=ABS((2*CLOSE+HIGH+LOW)/4-MA(CLOSE,20))/MA(CLOSE,20);
DD:=DMA(CLOSE,CC);
上:=(1+7/100)*DD;
下:=(1-7/100)*DD;
中:=(上+下)/2;
XG:BETWEEN(C,中*0.98,中*1.01);
DD:=DMA(CLOSE,CC);
上:=(1+7/100)*DD;
下:=(1-7/100)*DD;
中:=(上+下)/2;
XG:BETWEEN(C,中*0.98,中*1.01);
