源码：
VAR1:=REF(CLOSE,2);
A2: SMA(MAX(CLOSE-VAR1,0),7,1)/SMA(ABS(CLOSE-VAR1),7,1)*100, COLORGREEN;
超卖1: IF(A2<12,30,0);
VAR2:=REF(CLOSE,1);
VAR3:=SMA(MAX(CLOSE-VAR2,0),7,1)/SMA(ABS(CLOSE-VAR2),7,1)*100;
超卖2: IF(VAR3<12,30,0);
逢高派发区: STICKLINE(A2>80,A2+1,A2-1,8,0), COLORRED;
我走了！: IF(A2< REF(A2,1) AND A2>79,A2,0);
买点很少，中长线持有应该不错收益。
