第一个公式：先建立一个引用公式：
{引用WMA}
input:N(30,2,999);
WMA_H:WMA(HIGH,N);
WMA_L:WMA(LOW,N);
WMA_C:WMA(CLOSE,N);

第二个公式：{猎豹·火车轨（期货大赢家三轨）}
上轨:WMA(HIGH,30);
下轨:WMA(LOW,30);
日上轨:"引用WMA.WMA_H#day"(30);
日下轨:"引用WMA.WMA_L#day"(30);
S:=CROSS(CLOSE,日上轨);
X:=CROSS(日下轨,CLOSE);
WS:=BARSLAST(S)+1;
WX:=BARSLAST(X)+1;
SS:=CROSS(SUM(S,WX),0.5);
XX:=CROSS(SUM(X,WS),0.5);
DRAWICON(SS,LOW*0.995,4);
DRAWTEXT(SS,LOW,' \n \n买入'),ALIGN1,colorFFFFFF;
DRAWICON(XX,HIGH*1.01,5);
DRAWTEXT(XX,HIGH*1.02,'卖出'),ALIGN1,colorFFFFFF;
周上轨:"引用WMA.WMA_H#week"(30);
周下轨:"引用WMA.WMA_L#week"(30);
