Compare precentage difference in two items - trigger

[Golompg]

Hey,

I got two items that are showing me certain value from last day and from week ago. Is it possible to create a trigger that sends message when last day value is 15% less or 10% higher than value from week ago?

yes.. use time_shift parameter to move calculation point back in time and then compare results... I specifically do not give any example, as I do not know how you want to calculate things... maybe average over some period or sum or.. just last value...
