["Ermanno" <herman.web@xxxx>]

Hello,

I have to obtain the highest value of this data:

(abs(C-Ref(C,-1)));
(abs(Ref(C,-1)-Ref(C,-2)));
(abs(Ref(C,-2)-Ref(C,-3)));
(abs(Ref(C,-3)-Ref(C,-4)));
(abs(Ref(C,-4)-Ref(C,-5)));
(abs(Ref(C,-5)-Ref(C,-6)));
(abs(Ref(C,-6)-Ref(C,-7)));
(abs(Ref(C,-7)-Ref(C,-8)));
(abs(Ref(C,-8)-Ref(C,-9)));
(abs(Ref(C,-9)-Ref(C,-10)));

but I am not able to find the correct system?

Any suggest?

Thank you very much
Ermanno
