data2가 전일대비 몇틱 움직였는지 알수있는 방법이 있을까요?

아래와같이 data2의 pricescale와 대비(전일대비 얼마 움직였는지)를 알려고하는데
오류가 자꾸나네요
Data2가 몇틱을 움직였는지 알수있는 수식 부탁드립니다

--------------------------------------------------------------------------------

Input : Period(100);
Var : Data1대비(0), Data2대비(0);

Data1대비 = (C-dayclose(1))/PriceScale;
Data2대비 = (Data2(C)-data2(CloseD(1)))Data2(PriceScale);

Plot1(Data1대비,"Data1대비");
Plot2(Data2대비,"Data2대비");
