把“峰谷价势”修改成同花顺公式

看到“壹瓣”大师的“峰谷价势”很好，但其中有几个函数不能直接引用到同花顺中，比如PERIOD和DRAWBAND等，俺是菜鸟不知道在同花顺中用哪个函数替代，求老师帮改一下或告知对应的函数，谢谢！！！
源码：

{峰谷价势 - - 壹瓣杺埖 }
SS:=PERIOD;
自:=100*(HHV(H,6)-C)/(HHV(H,6)-LLV(L,6));
然:=100*(HHV(H,10)-C)/(HHV(H,10)-LLV(L,10));
峰1:=IF(自<50,自+70,120);
DRAWBAND(120,RGB(0,30,250),峰1,RGB(0,30,250));
谷1:=IF(自>50,自-50,0);
DRAWBAND(谷1,RGB(160,88,8),0,RGB(160,88,8));
R9:=IF(SS=2,80,9); RK3:=IF(SS=2,3,9); RD3:=IF(SS=2,10,9);
RSV:=(C-LLV(L,R9))/(HHV(H,R9)-LLV(L,R9))*100;
K:=SMA(RSV,RK3,1); D:=SMA(K,RD3,1); J:=3*K-2*D;

DRAWBAND(价,RGB(250,96,96),IF(价<谷2,谷2,价),RGB(250,96,96));

解答如下：

PERIOD:=COUNT(DATE<>REF(DATE,1),2)=2;
SS:=PERIOD;

然:=100*(HHV(H,10)-C)/(HHV(H,10)-LLV(L,10));
峰1:=IF(自<50,自+70,120);
FILLRGN(120,峰1,120<峰1,RGB(0,30,250),120>峰1,RGB(0,30,250));
谷1:=IF(自>50,自-50,0);
FILLRGN(谷1,0,0<谷1,RGB(160,88,8),0>谷1,RGB(160,88,8));
R9:=IF(SS=2,80,9); RK3:=IF(SS=2,3,9); RD3:=IF(SS=2,10,9);
RSV:=(C-LLV(L,R9))/(HHV(H,R9)-LLV(L,R9))*100;

价势:=J*1.1;
FILLRGN(价,峰2,价>峰2,RGB(0,180,220),价<峰2,RGB(0,180,220));
